Abstract

OBJECTIVE: To study the chemical constituents of Pouzolzia zeylanica. METHODS: Many chromatography means were used in separation and purification, and the structures of all compounds were identified by the means of spectroscopic analysis and physicochemical properties. RESULTS: 14 compounds were elucidated as: beta-sitosterol (1), daucosterol (2), oleanolic acid (3), epicatechin (4), alpha-amyrin (5), eugenyl-beta-rutinoside (6), 2alpha, 3alpha, 19alpha-trihydroxyurs-12-en-28-oic (7), scopolin (8), scutellarein-7-O-alpha-L-rhamnoside (9), scopoletin (10), quercetin (11), quercetin-3-O-beta-D-glucoside (12), apigenin (13), 2alpha-hydroxyursolic acid (14). CONCLUSION: All compounds are obtained from this plant for the first time.
