Objective:
To study the chemical constituents of Eriophyton wallichii.
Method:
The constituents were isolated and purified by silica gel column and Sephadex LH-20 chromatography. Their structures are elucidated by physicochemical properties and spectral analysis.
Result:
Seven compounds were obtained and identified as beta-sitosterol (1), marrubiin (2), ursolic acid (3), cimigoside (4), 5-deoxyantirrhinoside (5), 8-epiloganic acid (6) and apigenin 7-(6"-p-coumaroyl) glucoside (7).
Conclusion:
Compounds 1-7 were isolated from this plant for the first time.
