Özet

Six natural polar glycosides were isolated and identified from indigofera stachyoides radix,theywereidentifiedas β-sitosterol-D-glucoside (1), schizandriside (2), kaempferol-7-O-β-D-glucopyranoside(3), 3,4,5-trimethoxyphenyl-O-β-D-glucopyranoside (4), 2-methoxy-4-(2'-hydroxyethyl)–phenol-1-O-β-D-glucopyrano-side (5) and 2-(3-hydroxy-4-methoxyphenyl) ethyl 1-O-β-D-glucopyranoside (6). Meanwhile, fourflavonoids including7, 4'-dihydroxyl-3'-methoxyisoflavone (7), calycosin (8), 7-hydroxyl-4'-methoxyflavanone (9),maackiain (10)andone steroid compound,stigmasterol (11)were also reported herein.
