Objective To determine the content of crocin-1 in Zhizi Jinhua Wan, Yuye Qinghuo and Qinghuizhuo Oatmeal respectively. Methods The crocin-1 isolated from the previous period was used as the reference substance. The contents of cedrylin-1 in the three Chinese medicines containing gardenia were determined by ultra performance liquid chromatography (UPLC). Results The accuracy and precision of the UPLC method were high and the method was stable. The content of crocin-1 in the three drugs was 0.0121% ~ 0.0148%. Conclusion The method used is accurate, simple and rapid and can be used to control the content of crocin-1 in Chinese patent medicine.
