Flavonol Glycosides from leaves of salvia africana beneath

ABSTRACT

Four known flavonol glycosides viz. isorhamnetin-3-0-beta-D-galactoside, kaempferol-3-0-robinobioside, isorhamnetin-3-0-[2G-rhamnosylrutinoside] and kaempferol-3-0-[2G-rhamnosylrutinoside] in addition to isorhamnetin and kaempferol have been isolated from the leaves of Salvia farinacea Benth. [F. Labiatae]. The structures of the isolated compounds were principally deduced by physical and chromatographic characters as well as spectroscopic analysis [H-NMR, 13C-NMR, FAB-MS and EI-MS]
