Abstract:

Rourea harmandiana Pierre. is a species which belongs to the family of Connaraceae. This plant is found abundantly in central of Vietnam (Thua Thien - Hue, Da Nang). Chemical study on the ethyl acetate extract of Rourea harmandiana leaves  has led to the isolation of four compounds including vomifoliol (1), boscialin (2), abscisic acid (3) and p-coumaric acid (4). The structures of these compounds have been identified by NMR, MS spectroscopic data and comparison with the reported literature. These compounds were isolated from Rourea harmandiana species as well as from the genus Rourea for the first time.

Keywords: abscisic acid, boscialin, p-coumaric acid, Rourea harmandiana, vomifoliol.

Classification number: 2.2
