Abstract :Three new flavanone glycosides, naringenin 4`-O-b-D-glucuronopyranoside, naringenin 4`-O-a-L rham\-nopyranoside and naringenin 4`-O-b-D-xylopyranoside, were characterized from the leaves of Impatiens bicolor, together with 6 known glycosides: naringenin 4`-O-b-D-glucopyranoside, kaempferol 7-O-b-D-glucuronopyranoside, quercetin 3-O-b-D-glucopyranoside, kaempferol 5-O-b-D-xylopyranoside, kaempferol 3-O-b-D-galactopyranoside and kaempferol 7-O-b-D-xylopyranoside. The structures were determined by means of co-chromatography, UV, HPLC, EI-MS, FAB-MS and 1H NMR.
Keywords : Impatiens bicolor, Balsaminaceae, Naringenin 4` O b D glycosides
