OBJECTIVE To establish A RP-HPLC method for determination of oleanolic acid and ursolic acid in Damnacanthus indicus from different places. METHODS After ultrasonic extraction with 95% ethanol,the separation was achieved on a Kromasil C18 column at 25 degrees C using methanol-2.0% phosphoric acid solution (90:10, v/v) as the mobile phase at a flow rate of 0.8 mL/min. The detection wavelength was 210 nm. RESULTS Oleanolic acid showed good linear at the range of 0.124-1.24 microg (r = 0.9997). The recovery was 97.6% and RSD was 2.2%. Ursolic acid showed good linear at the range of 0.192-1.92 microg (r = 0.9999). The recovery was 102.4% and RSD was 1.9%. CONCLUSIONS The proposed method is simple and accurate. It can provide reliable evidence for quality control, development and utilization of Damnacanthus indicus.

UI	MeSH Term	Description	Entries
D009828	Oleanolic Acid	A pentacyclic triterpene that occurs widely in many PLANTS as the free acid or the aglycone for many SAPONINS. It is biosynthesized from lupane. It can rearrange to the isomer, ursolic acid, or be oxidized to taraxasterol and amyrin.	Oleanol,Hederins,Oleanane Triterpenes,Triterpenes, Oleanane
