The fruits of Ziziphus species have been utilized as food as well as crude drugs for their health benefits in China for thousands of years. This paper reported a reversed-phase high-performance liquid chromatography (HPLC) method for the simultaneous characterization and quantitation of 11 triterpenic acids in chloroform extracts of jujube fruits by using an evaporative light scattering detector (ELSD) and electrospray ionization−mass spectrometry (ESI-MS). The results showed that the contents of triterpenic acids in the fruits of Ziziphus jujuba var. spinosa were higher than those in the fruits of Z. jujuba, especially for the compound pomonic acid. Differences were also found among the different parts of Z. jujuba var. spinosa fruits with the sarcocarp having a higher amount of triterpenic acids than the seed and hard core.
