Objective: To develop a method for determination of phorbol ester in Jatropha curcas L extracts by HPLC. Meth-ods: Phorbol ester extract samples were diluted with CHCl3, filtered and injected into HPLC. The chromatographic separation was a-chieved on a reverse phase C18 column with gradient elution, using a mobile phase of acetonitrile/ water; detector wave was set at 280nm, column temptation was 25℃ , flow rate was 1. 0 ml/ min, and linear range was 15. 6-250 μg/ ml. Detection time was less than 40min. Results: The cablication curves of phorbol ester showed good linearity with correlation coefficient of 0. 9999. The mean recov-ery of spiked samples were from 91. 2% ~ 94. 6% . The RSD of precision was 1. 3% . The detection limits of phorbol ester was 5. 0μg/ mL. Conclusions: The results show that the method is simple and sensitive, and can be applied to routine analysis of phorbol ester in Jatropha curcas L extracts.
