RESUMO
Objective: To study the chemical constituents in the aerial parts of Tetracera asiatica. Methods: Silica gel, ODS, Sephadex LH-20 gel column chromatographies, and HPLC were used to isolate and purify the compounds. And the structures of the obtained compounds were identified by their physical properties and spectroscopic data. Results: Twelve compounds were separated and purified from the alcoholic extract of T. asiatica. They were identified to be rhamnocitrin (1), isorhamnetin (2), naringenin (3), rhamnetin (4), kaempferol (5), taxifolin (6), quercetin (7), tiliroside (8), quercetin-3-O-α-L-rhamnopyranoside (9), (-)-epicatechin 3-(3-O-methyl) gallate (10), epicatechin-3-O-gallate (11), and (-)-epicatechin (12). Conclusion: Compounds 1-12 are obtained from this plant for the first time.
