[Objectives]To establish a method for determining the content of caffeic acid in Zhuang Medicine Cryptolepis buchananii.[Methods]The content of caffeic acid in C.buchananii leaves was determined by high performance liquid chromatography(HPLC).[Results]The results of HPLC determination showed that the RSD values were less than 3%,and the content of caffeic acid in 10 batches of C.buchananii leaves was in the range of 0.0965%-0.4772%.[Conclusions]This method is accurate and reliable,has good linear relationship and high precision,and can be used for quality evaluation of C.buchananii.

[Results] The results of HPLC determination showed that the RSD values were less than 3%, and the content of caffeic acid in 10 batches of C. buchananii leaves was in the range of 0.096 5%-0.477 2%. [Conclusions] This method is accurate and reliable, has good linear relationship and high precision, and can be used for quality evaluation of C. buchananii.
