[Methods] High performance liquid chromatography was used for the determination of agfmophol in A. pilosa Ledeb. at different harvest time in Luzhou. [ Results ] The content of agrimophol could be detected by HPLC. Agrimophol had good linearity in 0.01 - 0.1 mg/ml ( r = 0.999 9 ), the average recov- ery was 101.5%, and RSD was 1.10%. The content of agrimophol in A. pilosa Ledeb. in Luzhou was 0.010 8% in June, and 0.013 1% in July, much higher than any other months. [ Conclusions] This experiment established a method for detecting the content of agrimophol by HPLC, which is simple, with high precision, high accuracy, good repeatability and recovery. The reasonable harvest time of A. pilosa Ledeb. in Luzhou is June and July.展开更多
