Isolation and Identification of Chemical Constituents of Excoecaria cochinchinensis Lour.

Abstract

Abstract: To study the chemical constituents of Excoecaria cochinchinensis Lour.The constituents were isolated by silica gel column chromatography,Chromatorex ODS chromatography,and sephadex LH-20 chromatography.Ten compounds were obtained from 80% ethanol extract of Excoecaria cochinchinensis Lour and their structures were identified as oleanolic acid (1),arjunolic acid (2),kaempferol (3),quercetin (4),isoscutellarein (5),scopoletin (6),3,4,5-trihydroxybenzoic acid (7),phloroglucinol (8), β-sitosterol (9) and daucosterol (10).Compounds 2,5 and 8 were isolated from the genus Excoecaria for the first time,compounds 1,4 and 6 were isolated from this plant for the first time.

Key words: Excoecaria cochinchinensis Lour., chemical constituent, extraction, isolation, structural identification
