Abstract:
Pistacides A and B (1-2), two new flavonoid glycosides, have been isolated from the methanolic extract of the aerial parts of Pistacia integerrima, along with 2'-hydroxyisoorientin (3), echioidinin 2'-O-beta-D-(6"-O-acetyl) glucopyranoside (4), chrysoeriol (5), and diandraflavone A (6), reported for the first time from this species. Their structures were elucidated by spectroscopic analysis including 2D NMR, FAB-MS, and acidic hydrolysis.
