Triterpenoid saponins from Cephalaria transsylvanica.

Two new triterpenoid saponins, transsylvanosides G and H, were isolated from Cephalaria transsylvanica and their structures established as 3-O-[beta-D-glucopyranosyl(1-->4)-beta-D-glucopyranosyl(1-->3)-alpha-L- rhamnopyranosyl(1-->2)-beta-D-xylopyranosyl] hederagenin 28-O-[beta-D-glucopyranosyl(1-->4)-beta-D-xylopyranosyl] ester (1) and 3-O-[beta-D-xylopyranosyl(1-->3)-alpha-L-rhamnopyranosyl-(1-->2)-beta-D- xylopyranosyl] hederagenin (2), respectively. A novel prosapogenin (3) was obtained on the alkaline hydrolysis of 1 and its structure defined as 3-O-[beta-D-glucopyranosyl(1-->4)-beta-D-glucopyranosyl(1-->3)-alpha-L- rhamnopyranosyl(1-->2)-beta-D-xylopyranosyl] hederagenin. The structures of compounds 1-3 were established by spectral and chemical methods.

A bidesmosidic triterpene saponin from Cephalaria transsylvanica.

The structure of cephalaria saponin B, isolated from Cephalaria transsylvanica was elucidated as 3-O-([beta-D-xylopyranosyl(1-->4)-alpha-L-rhamnopyranosyl(1-->2)-beta-D- xylopyranosyl]-[28-O-beta-D-glucopyranosyl])-3beta,23-dihydroxy-12(13)-oleanene-28-oic acid.

Triterpenoid glycosides from Cephalaria transsylvanica.

On the basis of spectroscopic and chemical methods, the structures of two new triterpenoid glycosides, transsylvanoside E and F, isolated from Cephalaria transsylvanica have been established as 3-O-[beta-D-xylopyranosyl (1-->3)-alpha-L-rhamnopyranosyl (1-->4)-beta-D-glucopyranosyl (1-->4)-beta-D-glucopyranosyl (1-->2)-beta-D-xylopyranosyl]-3 beta,23- dihydroxy delta 12-oleanen-28-carboxylic acid and 3-O-[beta-D-glucopyranosyl (1-->3)-alpha-L-rhamnopyranosyl (1-->4)-beta-D-xylopyranosyl]-28-O-[beta- D-glucopyranosyl (1-->4)-beta-D-glucopyranosyl]-3 beta,23-dihydroxy delta 12-oleanen- 28-carboxylic acid, respectively. A new proglycoside was isolated from the cleavage of the ester-glycoside linkage and it's structure characterized as 3-O-[beta-D-glucopyranosyl (1-->3)-alpha-L- rhamnopyranosyl (1-->4)-beta-D-xylopyranosyl]-3 beta,23-dihydroxy delta 12-oleanen-28-carboxylic acid.

An acidic triterpene glycoside from Cephalaria transsylvanica.

Transsylvanoside B, which is a new acidic triterpene glycoside, was isolated from dried flowers of Cephalaria transsylvanica. The structure was determined as 3-O-[beta-D- glucopyranosyl(1-->2)-beta-D-xylopyranosyl(1-->4)-alpha-L-rhamnopyran osy l (1-->4)-beta-D-xylopyranosyl]-3 beta,23-dihydroxy delta 12-oleanen-28-carboxylic acid.

Transsylvanoside A, an acidic triterpene glycoside from Cephalaria transsylvanica.

A new acidic triterpene glycoside, transsylvanoside A, was isolated from dried flowers of Cephalaria transsylvanica. The structure was determined to be 3-O-[beta-D-glucopyranosyl(1-->6)-beta-D-glucopyranosyl(1-->4)-al pha-L-rhamnopyranosyl(1-->4)-beta-D-xylopyranosyl]-3beta,23-dihydroxy delta(12)-oleanen-28-carboxylic acid.

Glucose-6-phosphate dehydrogenase deficiency in Cukurova Province, Turkey.

The prevalence of red cell G6PD deficiency was studied by a fluorescence screening test in 5 different ethnic populations of Cukurova province. Analyses were performed on samples from the parents of each family unit. The frequency of occurrence in the population was calculated using family trees. 4 551 subjects representing 17 225 offspring from 18 villages were screened and a high incidence of G6PD deficiency was found in the Arabic speaking ethnic groups from Adana (10.4%) and Anthiochus regions (8.1%), whereas the deficiency was only 3.1% in Armenians, 0.8% in mixed villages and 0.5% in Turcomans. This study reveals that the high frequency of this deficiency found in some ethnic populations must be taken into account prior to the treatment of malaria with primaquine.
