摘要：

Isolation of flavonoids from the aerial parts of Taverniera aegyptiaca Bioss. (Fabaceae) led to identification of one new flavonol glycoside, isorhamnetin-3-O-alpha-l-rhamnopyranosyl-(1 -> 2)-alpha-l-arabinopyranoside (1), along with eleven compounds, which previously have not been isolated from this plant quercetin-3-O-alpha-l-rhamnopyranosyl-(1 -> 2)-[alpha-l-rhamnopyranosyl-(1 -> 6)-beta-d-galactopyranoside] (2), isorhamnetin-3-O-alpha-l-arabinopyranoside (3), quercetin-3-O-alpha-l-rhamnopyranosyl-(1 -> 6)-beta-d-glucopyranoside (4), isorhamnetin-3-O-alpha-l-rhamnopyranosyl-(1 -> 6)-beta-d-glucopyranoside (7), isorhamnetin 3-O-alpha-l-rhamnopyranosyl-(1 -> 2)-[alpha-l-rhamnopyranosyl-(1 -> 6)-beta-d-galactopyranoside] (8), isorhamnetin 3-O-alpha-l-rhamnopyranosyl-(1 -> 2)-[alpha-l-rhamnopyranosyl-(1 -> 6)-beta-d-glucopyranoside] (9), kaempferol 3-O-alpha-l-rhamnopyranosyl-(1 -> 2)-[alpha-l-rhamnopyranosyl-(1 -> 6)-beta-d-galactopyranoside] (10), isorhamnetin (11), 4,4 '-dihydroxy-2 '-methoxychalcone (12), formononetin (13) and calycosin (15)] and some compounds already known from this plant [quercetin-3-O-robinobioside (5), isorhamnetin-3-O-robinobioside (6), afrormosin (14) and odoratin (16)].
