Abstract

Isolation of flavonoids from the aerial parts of Taverniera aegyptiaca
Bioss. (Fabaceae) led to identification of one new flavonol glycoside,
isorhamnetin-3-O-α-l-rhamnopyranosyl-(1→2)-α-l-arabinopyranoside
(1), along with eleven compounds, which previously have not
been isolated from this plant quercetin-3-O-α-l-rhamnopyranosyl-
(1→2)-[α-l-rhamnopyranosyl-(1→6)-β-d-galactopyranoside] (2),
isorhamnetin-3-O-α-l-arabinopyranoside (3), quercetin-3-O-α-lrhamnopyranosyl-(
1→6)-β-d-glucopyranoside (4), isorhamnetin-3-
O-α-l-rhamnopyranosyl-(1→6)-β-d-glucopyranoside (7), isorhamnetin
3-O-α-l-rhamnopyranosyl-(1→2)-[α-l-rhamnopyranosyl-(1→6)-β-dgalactopyranoside]
(8), isorhamnetin 3-O-α-l-rhamnopyranosyl-(1→2)-
[α-l-rhamnopyranosyl-(1→6)-β-d-glucopyranoside] (9), kaempferol
3-O-α-l-rhamnopyranosyl-(1→2)-[α-l-rhamnopyranosyl-(1→6)-β-
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-Orobinobioside
(5), isorhamnetin-3-O-robinobioside (6), afrormosin
(14) and odoratin (16)]
