The leaf of Diospyros kaki, which is a traditional Chinese medicine, has been used for the treatment of various diseases. In order to improve the quality assurance of the leaves of D. kaki, derived extracts and phytomedicines, a simple, rapid and accurate high-performance liquid chromatography(HPLC) method was developed to simultaneously assess the three bioactive triterpene acids: barbinervic acid (BA) and its epimer, rotungenic acid(RA), along with 24-hydroxy ursolic acid (HA). This HPLC assay was performed on a reversed-phase C18 column with methanol and aqueous H3PO4 as the mobile phase and using a monitoring wavelength at 210 nm. This method was successfully applied to quantify these three bioactive triterpene acids in five different solvent extracts of the leaves of D. kaki and in the leaves from six different locations in China.
