Genetic polymorphism of ferula mushroom growing on Ferula sinkiangensis.

Mating tests, internal transcribed spacer (ITS) sequence analysis, intergenic spacer 1-restriction fragment length polymorphism (IGS1-RFLP), IGS1 sequence analysis, and IGS2-RFLP analysis were carried out on isolates of 17 morphologically different Pleurotus mushrooms collected on Ferula sinkiangensis. The isolates were divided, based on mating tests and ITS sequence analysis, into two groups identical to P. eryngii var. ferulae and P. nebrodensis, respectively. Single spores from these two groups were incompatible, but those from P. eryngii var. ferulae and P. eryngii were compatible and combined to produce 56.25% dikaryon mycelia with clamp connections. The ITS of P. eryngii var. ferulae and P. nebrodensis (GenBank accession no. AY311408) were both 638 bp in size but differed by 3% in sequence. P. eryngii var. ferulae and P. eryngii (GenBank accession no. AY368658) were identical in ITS size and sequence. P. nebrodensis was the dominant population of Pleurotus mushroom growing on F. sinkiangensis. It exhibited genetic diversity. The two species could also be distinguished by IGSI-RFLP, similar to identification by mating tests and ITS sequence analysis. Difference in IGS1-RFLP existed between P. eryngii var. ferulae and P. nebrodensis. The sequence difference reached 2.28%. Both IGS1 size and IGS1-RFLP were similar among the different samples of P. nebrodensis. The 17 isolates were separated into five types based on IGS2 size and IGS2-RFLP, with both interspecies and extraspecies differences. P. nebrodensis exhibited polymorphism and was divided into four types. These results agreed with macroscopic differences. IGS2 might be the effective domain of genetically polymorphic ribosomal DNA in P. nebrodensis mushrooms found in Xinjiang, China.

Spasmolytic activity of essential oil and various extracts of Ferula gummosa Boiss. on ileum contractions.

Traditional herbal medicines such as Ferula gummosa Boiss. have been used for treatment of intestinal disorders in Iran. To date no pharmacological evidence for their effectiveness has been reported. The aim of this study was to examine the relaxant effect of essential oil, hydro-alcoholic, etheric, petrolic and methanolic extracts of Ferula gummosa and two of its components, alpha-pinene and beta-pinene, on isolated rat ileum contractions induced by KCl and acetylcholine (ACh). Ferula gummosa essential oil (FGEO) and hydro-alcoholic, etheric, petrolic and methanolic extracts all inhibited the response to 80 mM KCl in a concentration-dependent manner and attenuated the maximum attainable response of the ACh concentration-response curve. Although the effect of etheric extract on ACh contractions was less than that of petrolic extract, the overall order of effectiveness on the weight basis was the etheric, petrolic, methanolic, and hydro-alcoholic extracts, and the essential oil, respectively. A mixture of etheric and petrolic extracts together had a similar effect on KCl response to etheric extract was used alone. Alpha-pinene and beta-pinene both exhibited inhibitory effect on the contraction of rat ileum, but the inhibitory effect of beta-pinene on KCl contraction was more pronounced. The inhibitory effect of a mixture of these two compounds was, however, less than the sum of their separate effects. When a mixture of alpha-pinene and beta-pinene together were examined on the ileum, without presence of the spasmogen, they initially caused contraction of the tissue, while neither of them used alone caused a noticeable contraction of the ileum. This study shows that Ferula gummosa essential oil and its various extracts are relaxant of rat isolated ileum and that at least part of their inhibitory effect is due to alpha-pinene and beta-pinene components. As the inhibition of contractile over-activity of the ileum is the basis of the treatment of some gastero-intestinal disorders such as diarrhea, Ferula gummosa may have clinical benefits for treatment of this condition.

Antispasmodic and hypotensive effects of Ferula asafoetida gum extract.

The effects of Ferula asafoetida gum extract on the contractile responses of the isolated guinea-pig ileum induced by acetylcholine, histamine and KCl, and on the mean arterial blood pressure of rat were investigated. In the presence of extract (3 mg/ml), the average amplitude of spontaneous contractions of the isolated guinea-pig ileum was decreased to 54 +/- 7% of control. Exposure of the precontracted ileum by acetylcholine (10 microM) to Ferula asafoetida gum extract caused relaxation in a concentration-dependent manner. Similar relaxatory effect of the extract was observed on the precontracted ileum by histamine (10 microM) and KCl (28 mM). However, when the preparations were preincubated with indomethacin (100 nM) and different antagonists, such as propranolol (1 microM), atropine (100 nM), chlorpheniramine (25 nM) then were contracted with KCl, exposure to the extract (3 mg/ml) did not cause any relaxation. Furthermore, Ferula asafoetida gum extract (0.3-2.2 mg/100g body weight) significantly reduced the mean arterial blood pressure in anaesthetised rats. It might be concluded that the relaxant compounds in Ferula asafoetida gum extract interfere with a variety of muscarinic, adrenergic and histaminic receptor activities or with the mobilisation of calcium ions required for smooth muscle contraction non-specificly.

Ferula harmonis 'zallouh' and enhancing erectile function in rats: efficacy and toxicity study.

Ferula harmonis, which is locally called 'zallouh' in the Middle East, is used as an aphrodisiac as it is reputed to enhance male sexual behavior, however, there is no scientific verification. In this study, the oil extracted from the seeds of Ferula harmonis was tested for its efficacy in enhancing erectile function and toxicity in male rats. The sexual activities assessed by penile erection index were dose dependent. The ED(50) (12.03 mg/kg) was 880 times less than the LD(50) (10.6 g/kg). However, when doses ranging from 0.05, 0.5 to 2 g/kg were given daily for 28 days, acute and subacute toxicity were observed. There was a decrease in total body weight, hepatomegaly, atrophic testis, significant decrease in hemoglobin and red blood cell count. In addition, there was a significant decrease in cholesterol level. All the above indicate that the crude oil from the plant Ferula harmonis can enhance erectile function, however, it becomes toxic if it is used for a long period of time. Further studies are underway to isolate and identify the active ingredients and their exact mechanisms of action.

Antiproliferative effects of daucane esters from Ferula communis and F. arrigonii on human colon cancer cell lines.

Certain jaesekanadiol p-hydroxy- and p-methoxybenzoates - typical of Ferula communis and Ferula arrigonii sardinian plants - show antiproliferative activity on human colon cancer less. The inhibitory doses 50%, calculated after 72 h of treatment, revealed that the antiproliferative capacity of the compounds was in the following descending order: ferutinin > 2alpha-OH-ferutidin > ferutidin > siol anisate > lapiferin > jaeskeanadiol. Evidence is presented that interaction with type II estrogen-binding sites (EBS) underlies this activity.

Novel antioxidants isolated from plants of the genera Ferula, Inula, Prangos and Rheum collected in Uzbekistan.

We examined the effects of 48 compounds isolated from Ferula pallida, F. penninervis, Inula macrophylla, Prangos pabularia, P. tschimganica and Rheum maximowiczii collected in Uzbekistan on ADP/Fe2+-induced lipid peroxidation of egg yolk phosphatidylcholine liposomes. Of those compounds, 23 inhibited ADP/Fe2+-induced lipid peroxidation and nine showed especially strong inhibition of lipid peroxidation. Most compounds that inhibited peroxidation scavenged the 1,1'-diphenyl-2-picrylhydrazyl (DPPH) radical, indicating that the inhibition was due to radical scavenging. However, some compounds did not scavenge DPPH but inhibited lipid peroxidation significantly, suggesting that their inhibitory effect was not due to radical scavenging but to some other mechanism, such as prevention of Fe2+ function. Thus, we found various new antioxidants, some of which had a unique mechanism of action, in Ferula, Inula, Prangos and Rheum plants collected in Uzbekistan as seeds used in medicine.

Sesquiterpene coumarins from Ferula szowitsiana and in vitro antileishmanial activity of 7-prenyloxycoumarins against promastigotes.

Two new sesquiterpene coumarins, named szowitsiacoumarin A (1) and szowitsiacoumarin B (2), and a phenylpropanoid derivative, 2-epihelmanticine (3), together with nine known compounds, auraptene (4), umbelliprenin (5), galbanic acid (6), methyl galbanate (7), farnesiferol B (8), farnesiferol C (9), persicasulfide A (10), beta-sitosterol and stigmasterol were isolated from the roots of Ferula szowitsiana. The structures of these compounds were elucidated by extensive spectroscopic methods including 1D-((1)H and (13)C) and 2D-NMR experiments (DQF-COSY, HSQC, HMBC, and ROESY) as well as HR-MALDI-MS analysis. Since the configuration of 2-epihelmanticine was previously only partly determined, a relative configurational analysis of its four stereocenters was carried out on the basis of the recently reported J-based method. The inhibiting activity of prenylated coumarins, auraptene (4) and umbelliprenin (5), in addition to galbanic acid (6), as major component, and of the Me(2)CO extract of Ferula szowitsiana (Apiaceae) roots has been evaluated against promastigotes of Leishmania major. Umbelliprenin and auraptene showed significant activity with IC(50) values of 4.9microg/ml (13.3microM) and 5.1microg/ml (17.1microM) after 48h incubation, respectively.

Conferone from Ferula schtschurowskiana enhances vinblastine cytotoxicity in MDCK-MDR1 cells by competitively inhibiting P-glycoprotein transport.

Overexpression of the protein transporter P-glycoprotein (Pgp, MDR1) at the cell surface is a major cause of multidrug resistance (MDR) and poor response to treatment in cancer chemotherapy and therapy for leishmaniasis. The present study shows that conferone, a sesquiterpene coumarin ether isolated for the first time from Ferula schtschurowskiana, endemic in Uzbekistan, enhances the cell toxicity of vinblastine (VBL) in MDR1-transfected Madin-Darby canine kidney (MDCK-MDR1) cells. Conferone presents the advantage to mediate this effect at safe concentrations. At 10 microM, it efficiently competes with the photoactivatable cyclosporin A analogue (SDZ 212 - 122) for the binding to Pgp and accumulates [3H]-VBL to a higher extent than cyclosporin A or cnidiadin. [3H]-VBL accumulation is dose-dependent and correlates with the inhibition of Pgp photolabeling affinity, supporting the hypothesis that conferone sensitizes MDCK-MDR1 cells to VBL by competitively inhibiting drug efflux. In MDCK-MDR1 cells, [3H]-VBL accumulation appears to be almost completely dependent on inhibition of Pgp transport. However, the strict specificity of conferone to this efflux pump has to be demonstrated in cell lines expressing other protein transporters. Collectively, our findings identify conferone as a powerful modulator of Pgp transport and a promising molecule for the treatment of MDR malignancies and leishmaniasis. Complementary in vitro and in vivo studies are, however, needed to assess the value of conferone as a reversal drug in human therapy. Considering its high affinity for Pgp, conferone may have an additional usefulness as a tool for the design or the (hemi)synthesis of agents probing Pgp. To our knowledge, this is the first report identifying sesquiterpene coumarins from Ferula as possible drug candidates for the reversion of MDR encoded by the MDR1 gene or the synthesis of agents probing Pgp.

Sesquiterpene coumarins from Ferula fukanensis and nitric oxide production inhibitory effects.

Four new sesquiterpene coumarin derivatives, fukanemarin B (1), fukanefuromarin E (2), fukanefuromarin F (3) and fukanefuromarin G (5) were isolated from a 80% aqueous methanol extract of the roots of Ferula fukanensis. The structures were elucidated based on spectral evidence, especially heteronuclear multiple-bond connectivity (HMBC) and high-resolution MS. The 80% aqueous methanol extract of the roots of Ferula fukanensis (FFE) and the sesquiterpene coumarin derivatives inhibited nitric oxide (NO) production and inducible NO synthase (iNOS) gene expression by a murine macrophage-like cell line (RAW 264.7), which was activated by lipopolysaccharide (LPS) and recombinant mouse interferon-gamma (IFN-gamma).

[Anticoagulant activity of coumarins from Ferula communis L].

Ferula communis is an ombelliferous plant of the Mediterranean regions. It is represented in Morocco by two varieties: brevifolia and genuina. The later is very rich in a soap or resinous gum. This product, collected from the roots, is largely used in traditional medicine. It is know as fessoukh in Morocco and other Arab countries. This plant is also well known for its toxicity and its anticoagulant activity. In the present review, are discussed: (1) the ethnobotany of the plant, especially medicinal uses of fessoukh in traditional medicine as well as alimentary use of young stems as legumes; (2) clinical and biochemical data of intoxication by this plant, which are dominated by haemorrhage as a consequence of blood coagulation disturbance; (3) 4-hydroxycoumarins isolated from Ferula communis L. and their anticoagulant activity; (4) the role of vitamin K1 in the treatment of poisoning by this plant.

Experimental studies on the toxicity of Ferula communis in the rat.

The study of two chemically characterized varieties of Ferula communis showed that only plants containing prenylated coumarins are toxic. The contrasting data on the toxicity of Ferula communis most probably raised from the use of chemically uncharacterized specimens. Among the constituents of the toxic variety, both ferulenol, a 4-hydroxycoumarin derivative, and ferprenin, a pyrane (3,2-c) coumarin derivative, affected blood clotting. No hepatotoxicity was elicited by these two compounds.

Genetic diversity and population structure of the Italian fungi belonging to the taxa Pleurotus eryngii (DC.:Fr.) Quèl and P. ferulae (DC.:Fr.) Quèl.

A study using allozymes and PCR fingerprinting was conducted to estimate the genetic diversity of Italian populations of two economically important cultivated fungal taxa, Pleurotus eryngii and P. ferulae. Very little is known about the genetic diversity distribution pattern of these taxa. Heterozygote deficiency was observed at few loci; in fact the inbreeding coefficients were not high, which demonstrates that mechanisms restrain the inbreeding act at the local level. Estimates of genetic differentiation indicated a pattern of greater variation within, rather than between, populations. These results were supported by AMOVA analysis, which attributed a low proportion of the total genetic variation to large geographical scale divergence, and indicated that most of the genetic diversity was because of differences within populations. This distribution pattern of genetic variation of P. eryngii and P. ferulae populations seems to be the result of high gene flow, by efficient basidiospore dispersal, and outcrossing mechanisms, which restrain inbreeding within populations.

Antimycobacterial constituents from Juniperus procera, Ferula communis and Plumbago zeylanica and their in vitro synergistic activity with isonicotinic acid hydrazide.

The synergistic activity of antimycobacterial constituents from Saudi plants was evaluated in combination with isonicotinic acid hydrazide (INH) against four atypical organisms, namely, Mycobacterium intracellulare, M. smegmatis, M. xenopei and M. chelonei. The potency of INH was increased four-fold, using an in vitro checkerboard method, against each mycobacteria when tested with a subtoxic concentration of the totarol, isolated from J. procera. The MIC values of totarol, ferulenol (from Ferula communis) and plumbagin (from Plumbago zeylanica) were thus lowered from 1.25-2.5 to 0.15-0.3 microg/mL due to synergism with INH. When tested against the resistant strain of M. tuberculosis H37Rv, plumbagin and 7beta-hydroxyabieta-8,13-dien-11,12-dione exhibited inhibitory activity at <12.5 microg/mL, while others were inactive at this concentration.

Postcoital contraceptive action in rats of a hexane extract of the aerial parts of Ferula jaeschkeana.

The hexane extract of Ferula jaeschkeana aerial parts was studied at an oral dose of 25 mg/kg per day for its postcoital effects in pregnant rats. Ovaries of treated rats remained in a cyclic state rather than undergoing pregnancy as demonstrated by constant ovulation accompanied by newly formed corpora lutea. Follicles were present in different stages of development. Uterine histoarchitecture of treated rats appeared non-receptive for implantation. No decidcoma were observed on day 5 of pregnancy and the luminal epithelium remained unresponsive. Uterus was non-oedematous and lumen was considerably wider. Administration of the extract caused increases in the protein and glycogen content of ovary and uterus, while the activity of acid phosphatase remained essentially unchanged and the activity of alkaline phosphatase was increased. The volume of uterine fluid in the treated rats was increased considerably on day 5 post coitum. It appears that the histological and biochemical modifications in the ovary and uterus of treated pregnant rats do not support the preparation of uterus for implantation.

Molluscicidal activity of Ferula asafoetida, Syzygium aromaticum and Carum carvi and their active components against the snail Lymnaea acuminata.

The molluscicidal activity of dried root latex powder of Ferula asafoetida, flower-bud powder of Syzygium aromaticum and seed powder of Carum carvi against the snail Lymnaea acuminata was studied. The molluscicidal activity of all the three plant products was found to be both time and concentration dependent. The toxicity of S. aromaticum flower-bud powder (96 h LC(50):51.98 mg/l) was more pronounced than that of root latex powder of F. asafoetida (96 h LC(50):82.71 mg/l) and seed powder of C. carvi (96 h LC(50):140.58 mg/l). Ethanol extract was more toxic than other organic extracts. The ethanol extract of S. aromaticum (24h LC(50):83.53 mg/l) was more effective than that of F. asafoetida (24h LC(50):132.31 mg/l) and C. carvi (24h LC(50):130.61 mg/l) in killing the test animals. The 96 h LC(50) of column purified fraction of seed powder of C. carvi was 5.40 mg/l whereas those of flower-bud powder of S. aromaticum and dried root latex powder of F. asafoetida were 7.87 and 9.67 mg/l, respectively. The product of F. asafoetida, S. aromaticum and C. carvi may be used as potent molluscicides.

Role of energy metabolism in the pregnancy interceptive action of Ferula assafoetida and Melia azedarach extracts in rat.

Ethanolic extract of Ferula assafoetida and chloroform fraction of Melia azedarach, both devoid of estrogenic activity, were examined for their pregnancy interceptive property. Treatment of rats from days 1 to 7 of pregnancy with either of the plant extracts resulted in pregnancy failure in about 65-85% of the animals. The possible role of energy metabolism in the antifertility action was investigated by measuring changes in activities of the key enzymes of carbohydrate metabolism in uterus on day 7 of pregnancy. It was observed that on the day 7 of pregnancy, one key enzyme of glycolytic pathway (phosphofructokinase) was significantly reduced in the uteri of treated rats as compared to controls. Hexosemonophosphate pathway also appeared to be sensitive to treatment with the plant extracts and showed an inhibitory effect on the enzyme activities of glucose-6-phosphate dehydrogenase and 6-phosphogluconate dehydrogenase. Oxidative energy metabolism through tricarboxylic acid cycle, which is considered to be the main source of energy to the uterus at this stage, was maximally affected by the treatment with several enzymes showing significant inhibition. The two plant materials appeared to interrupt the latter metabolic pathway more significantly. It is thus concluded that plants lacking phytoestrogens may intercept pregnancy by their ability to disrupt energy metabolism in rat uterus during implantation, especially the oxidative pathway.

HPLC-DAD-MS identification of bioactive secondary metabolites from Ferula communis roots.

A simple HPLC method was developed to distinguish between 'poisonous' and 'non-poisonous' chemotypes of Ferula communis. The method was performed on a C8 reverse phase analytical column using a binary eluent (aqueous TFA 0.01%-TFA 0.01% in acetonitrile) under gradient condition. The two chemotypes showed different fingerprints. The identification of five coumarins and eleven daucane derivatives by HPLC-diode array detection (HPLC-DAD) and HPLC-MS is described. A coumarin, not yet described, was detected.
