Abstract:

Ten compounds were isolated from the leaves of Microcos paniculata L. On the basis of spectral data, they were identified as friedelin (1), arjunglucosideⅡ (2), kaempferol-3-O-β-D-[3,6-di-(p-hydroxycinnamoyl)]-glucopyranoside (3), kaempferol-3-O-b-D- glucopyranoside (4), isorhamnetin-3-O-β-D-glucopyranoside (5), narcissin (6), vitexin (7), violanthin (8), isoviolanthin (9) and isovitexin (10). All these compounds were obtained from this plant for the first time.
