ABSTRACT
Objective:
To study the bioactive flavonoids from Bidens pilosa.Methods:
Various chromatographic methods including silica gel and Sephadex LH-20 columns, middle pressure liquid chromatography, and high speed counter current chromatography were applied to isolating and purifying the compounds. Their structures were confirmed based on the physicochemical properties and spectral data.Results:
Six compounds were isolated from the ethyl acetate extract of B. pilosa, and their structures were identified as 2(R/S)-isookanin-3, 4'-dimethyl ether-7-O-β-D-glucopyranoside (1a-1b), quercetin-3, 4'-dimethyl ether-7-O-glucoside (2), quercetin 3, 4'-dimethyl ether-7-O-rutinoside (3), (Z)-6-O-(6'-O-acetyl-β-D-glucopyranosyl)-6, 7, 3', 4'-tetrahydroxyaurone (4), maritimein (5), and okanin 4-methyl ether-3'-O-β-glucoside (6).Conclusion:
Compound 1a-1b is a novel compound named bidenoside H.
