Content Determination of Oleanolic Acid and Ursolic Acid in Fresh-cut Chaenomeles S peciosa (Sweet) Nakai
The purpose of this paper is to provide scientific basis for improving the quality of Chaenomeles Speciosa (Sweet) Nakai and through comparing the contents and HPLC fingerprint of oleanolic acid and ursol-ic acid in different prepared slices. The contents of oleanolic acid and ursolic acid in different prepared slices of Chaenomeles Speciosa(Svueet) Nakai. Were determined by high performance liquid chromatography (HPLC) method; and the difference in their HPLC fingerprint were also compared and discussed. There were not remarkable componential difference in four different samples, and all of them exhibited 27 peaks in HPLC fingerprints. However, the contents of oleanolic acid and ursolic acid in different samples were very diverse; and their total contents in fresh-cut slices were the same as in fresh Chaenomeles Speciosa (Sweet) Nakai. With the content of 0. 89%. Fresh-cut slices of Chaenomeles Specios a(Sweet) Nakai. Overcome the shortcomings of traditional processing methods for the benefit of comprehensively retaining the content of oleanolic acid, ursolic acid and other medicinal ingredients, which are beneficial for ensuring drug quality and worthy of widely application.
