[Abstract]
Objective To study the chemical constituents from ethyl acetate extract from canes of Entada phaseoloides. Methods The compounds were separated and purified by column chromatography on silica gel, RP C18, and Sephadex LH-20, and were identified by MS and NMR. Results Eleven compounds were isolated from the ethyl acetate fraction in methanol extract from canes of E. phaseoloide, and their structures were elucidated as epi-gallocatechin gallate (1), epicatechin gallate (2), astilbin (3), luteolin (4), (?)-epicatechin (5), liquiritin (6), mixture of β-amyrin (7) and germanicol (8), gallic acid (9), β-sitosterol (10) and daucosterol (11). Conclusion Compounds 1—11 are isolated from this plant for the first time. Compounds 1—9 are firstly reported in the plants of Entada Adans.
