Chemical constituents of leaves of Passiflora Incarnata Linn. (Passifloraceae)

Abstract

In the investigation of the Chemical constituents of the ethyl acetate extract of Passiflora incarnata Linn., collected at Dong Hoa district, Phu Yen province, six compounds were isolated. They were one megastigmane, dehydrovomifoliol (1), three megastigmane monoglycosides, roseoside (2), byzantionoside B (3) and foliasalacioside L (4), one flavone C- monoglycoside vitexin (5) and one nucleotide glycoside uridine (6). Their Chemical structures were elucidated hy means of HR-MS, 1D and 2D-NMR data analysis and the comparison their NMR data with those reported in the literature. Although, these compounds had already reported in the other species, they were known in Passiflora incarnata Linn. for the first time to the best of our knowledge.
