Objective:To study the chemical constituents from the herb of Kummerowia striata. Method:The compounds were isolated and purified by column chromatographic methods with Sephadex LH-20
silica gel
ODS and preparation HPLC. Their structures were identified by physicochemical properties and spectral data. Result:Fourteen compounds were isolated and elucidated as quercetin-3-O-β-D-galactopyranoside (1)
kaempferol-3-O-β-Dglucopyranoside (2)
apigenin-7-O-neohesperidoside (3)
apigenin-7-O-β-D-glucopyranoside (4)
stigmasterol-3O-β-Dglucopyranoside (5)
quercetin (6)
quercetin-3-O-glucosideⅠ(7)
rutin (8)
luteolin (9)
apigenin (10)
kaempferol (11)
stigmasterol (12)
β-sitosterol (13)
daucosterol (14)
respectively. Conclusion:Compounds 1
5
7-9 and 11-14 were isolated from K. striata for the first time.
