Research Abstract

Mandelonitrile--D-glucopyranoside (prunasin) (1), kaempferol- 3-O--D-galactopyranoside (2), kaempferol-3-O--D-glucopyranoside (3), quercetin-3-O--D-glucopyranoside (4), mandelic acid amide--D-glucopyranoside (5), kaempferol-3-O-[-D-glucopyranosyl-(14)--D-galactopyranoside] (6), mandelonitrile--D-glucopyranosyl-(16)- -D- glucopyranoside (amygdalin) (7) were isolated from the methanolic extract of the leaves of Prunus persica (L.) Batsch “Meet Ghamr” peach. Furthermore, persicogenin (8), naringenin (9), aromadenderin (10), eriodictyol (11), persicogenin-3-O--D-glucopyranoside (12) and hesperitin-5-O--D-glucopyranoside (13) were isolated from the methanolic extract of the stem bark of the title plant. All these compounds were isolated for the first time from “Meet Ghamr“ peach while compounds 5 and 6 were firstly reported from the genus Prunus. Identification of these compounds has been established by physical, chemical and spectral methods (UV, IR, FAB-MS, 1-D-and 2-D NMR).
