The compounds were isolated and purified by column chromatography of HP-20 macroporous resin, silica gel, ODS, Sephadex LH-20, and semi-preparative RP-HPLC. Their structures were elucidated by physicochemical properties and spectral analyses.Results:
Eight compounds were isolated and identified as 7,3’,4’-trimethoxylquercetin-3-O-α-L-arabinadosyl-(1→6)-O-β-D-glucopyranoside (1), 7,3’,4’-trimethoxylquercetin-3-O-rutoside (2), quercetin-3-O-β-D-glucopyranoside (3), (2E,6S)-8-[α-L-arabinopyranosyl-(1″→6’)- β-D-glucopyranosyl]-2,6-dimethyloct-2-eno-1,2″-lactone (4), kankanoside E (5), betulalbuside A (6), shomaside F (7), and amarantholidoside V (8), respectively.Conclusion:
