Abstract:
Objective To study the chemical constituents of Aspidopterys obcordate. Methods The chemical constituents from 95% EtOH extract of the stem of A. obcordate were isolated by repeated chromatograph with silica gel, Sephadex LH-20, and ODS. The structures were elucidated by spectroscopic analysis. Results Eight compounds were isolated and identified as 3,4-dihydroxybenzoic acid-3-O-α-L-rhamnoside (1), 3,4-dihydroxyphenyl acetate (2), 3,4-dihydroxybenzoic acid (3), catechin (4), β-sitosterol (5), daucosterol (6), cinnacasolide C (7), and alantan (8). Conclusion Compound 1 is a new compound, named as apobcoroside. All compounds are isolated from the plant of A. obcordate for the first time.
