  Flavonol Glycosides fromJatropha variegata

  摘要：

  Five flavonoids were isolated from stems of Jatropha variegata (Forsk.) Vahl, the structures of which were identified as kaempferol 3-O-alpha-L-rhamnopyranoside, 3-O-alpha-L-arabinoppranoside, 3-O-beta-D-glucopyranoside, 3-O-beta-D-galactopyranoside and kaempferol.
