Abstract:
Objective: To study chemical constituents of Argyreia acuta. Methods: The chemical constituents were isolated and purified by silica gel, macroporous resin adsorption, MCI GEL CHP 20P, Sephadex LH-20 chromatography, and preparative liquid chromatography. Their structures were identified by physicochemical properties and spectral analysis. Results: Ten compounds were isolated and identified as ethyl caffeate (1), hispidulin (2), quercetin (3), scopolin (4), paprazine (5), mannitol (6), hesperetin (7), ipalbidinium-4’-O-β-D-(6-O-trans-coumaroyl)-glucoside (8), nepitrin (9), and homoplantaginin (10). Conclusion: Compound 8 is a new compound named argyreiacutine, and compounds 2, 3, 6, 7, 9, and 10 are isolated from A. acuta for the first time.
