E-senegasaponins A and B, Z-senegasaponins A and B, Z-senegins II and III, new type inhibitors of ethanol absorption in rats from senegae radix, the roots of Polygala senega L. var latifolia Torrey et Gray.

New inhibitors of ethanol absorption, E-senegasaponins a and b, Z-senegasaponins a and b, Z-senegins II and III, were isolated from Senegae Radix, the roots of Polygala senega L. var latifolia Torrey et Gray, together with senegins II and III. Their chemical structures have been elucidated on the basis of chemical and physicochemical evidence, and the geometrical isomeric structures of methoxycinnamoyl moiety in each saponin were found to show tautomer-like behavior. The inhibitory effects of senegasaponins, senegins, and their related compounds have been examined, and some structure-activity relationship have been found.

Inhibitory effect of interleukin-1alpha-induced apoptosis by Polygala tenuifolia in Hep G2 cells.

A human hepatoma cell line, Hep G2 cells are reliable for the study of alcohol-induced hepatotoxicity. In this study, we investigated the effect of an aqueous extract of Polygala tenuifolia WILLDENOW (Polygalaceae) roots (PTAE) on ethanol (EtOH)-induced cytotoxicity in Hep G2 cells. PTAE (0.01-1 microg/ml) dose-dependently inhibited the EtOH-induced interleukin-1alpha (IL-1alpha) secretion. PTAE (0.01-1 microg/ml) also inhibited the EtOH- and IL-1alpha-induced cytotoxicity. Furthermore, we found that PTAE inhibited the IL-1alpha-induced apoptosis of Hep G2 cells. These results suggest that PTAE may prevent the EtOH-induced cytotoxicity through inhibition of the apoptosis of Hep G2 cells.

Two new compounds were isolated from the roots of Polygala arillata Buch-Ham. On the basis of chemical reactions and spectral (UV, IR, MS, 1HNMR, DIFNOE, 13CNMR) analysis, they were identified as 1,3-dihydroxy-2-methoxyxanthone(I) and 7-hydroxy-1-methoxy-2,3-methylenedioxyxanthone(II). Pharmacological study indicated that I and II have inhibitory effect on aldose reductase activity.

Isolation and identification of tetrahydrocolumbamine as a dopamine receptor ligand from Polygala tenuifolia Willd.

The isolation and purification of a dopamine receptor ligand, tetrahydrocolumbamine from Polygala tenuifolia Willd is described. Tetrahydrocolumbamine was shown to inhibit the binding of [3H]-SCH23390 and [3H]-spiroperidol to rat striatum membranes in vitro with IC50 values of 0.75 +/- 0.08 mumol.L-1 and 0.92 +/- 0.10 mumol.L-1, respectively. The compound inhibited the binding of [3H]-prazosin (IC50 value of 46 mumol.L-1), while it did not change the binding of the ligands, [3H]-QNB and [3H]-muscimol to rat cortex in vitro. Scatchard plot analysis showed a mixture of competitive and non-competitive inhibition by the compound on both [3H]-SCH23390 and [3H]-spiroperidol binding to membranes from rat striatum.

OBJECTIVE: To study the chemical constituents in roots of P. fallax and their anti-oxidation activities in vitro. METHOD: Column chromatographic techniques were employed for isolation and purification of chemical constituents of the plant.

And compounds 1 - 7 showed different anti-oxidation activities in the different pharmacological models. CONCLUSION: Compounds 2, 3, 5 and 7 were isolated from this plant for the first time. Xanthones from this plant showed anti-oxidation activities. The pharmacological activities of the pure compounds from this plant were also reported for the first time.
