Abstract: New flavonoid glycoside, kaempferol 3-O-α-[(6-P-coumaroyl galactopyranosyl-O-β-(1 → 4)-O-α-rhamnopyranosyl-(1 → 4)]-O-α-rhamnopyranoside 1, in addition to five known flavonoid glycosides (2-6) kaempferol 3-O-[α-rhamnopyranosyl-(1 → 4)-O-α-rhamnopyranosyl-(1 → 6)-O]-β-galactopyranoside (kaempferol 3-O-β-isorhamninoside) 2, quercetin 3-O-[(2,3,4-triacetyl-α-rhamnopyranosyl)-(1 → 6)-β-galactopyranoside 3, quercetin 3-O-[(2,4-diacetyl-α-rhamnopyranosyl)-(1 → 6)]-3,4-diacetyl-β-galactopyranoside 4, quercetin 3-O-[(2,4-diacetyl-α-rhamnopyranosyl)-(1 → 6)]-2,4-diacetyl-β-galactopyranoside 5, quercetin 3-O-[(2,3,4-triacetyl-α-rhamnopyranosyl)-(1 → 6)-3-acetyl-β-galactopyranoside 6 were isolated from… read more here.
