Novel flavonol glycoside from Retama sphaerocarpa Boissier

Abstract A novel flavonol glycoside, rhamnazin-3- O - β -glucopyranosyl-(1→5)- α -arabinofuranoside, was isolated from the aerial parts of Retama sphaerocarpa (Fabaceae) and its structure determined by mp, UV, IR, FAB-MS, GC–MS and NMR data.
