Isoflavonoid glycosides and rotenoids from Pongamia pinnata leaves.

چکیده
Chromatographic separation of a 70% aqueous methanol extract (AME) of Pongamia pinnata (Linn.) Pierre (Leguminosae) leaves has led to the isolation of two new isoflavonoid diglycosides, 4'-O-methyl-genistein 7-O-beta-D-rutinoside (2) and 2',5'-dimethoxy-genistein 7-O-beta-D-apiofuranosyl-(1"'-->6")-O-beta-D-glucopyranoside (6), and a new rotenoid, 12a-hydroxy-alpha-toxicarol (5), together with nine known metabolites, vecinin-2 (1), kaempferol 3-O-beta-D-rutinoside (3), rutin (4), vitexin (7), isoquercitrin (8), kaempferol 3-O-beta-D-glucopyranoside (9), 11,12a-dihydroxy-munduserone (10), kaempferol (11), and quercetin (12). Their structures were elucidated on the basis of chemical and spectroscopic analyses.
