title: [Study on the chemical constituents in Pouzolzia zeylanica].
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).
  
  
  CONCLUSIONS
  All compounds are obtained from this plant for the first time.
