Abstract:
Modern research showed that components in the dried leaf of Cyclocarya paliurus. had various biological activities. The current quality control research was focused on content determination of polysaccharides and flavonoids, while there were less research on quantitative analysis of terpenes and phenolic acids. In this paper, the contents of 16 components of 3 kinds in C. paliurus leaf were determined by UPLC-QE-Orbitrap-MS. The results were as following: good linear relationship of 16 analytes existed within the studied concentration rages (²>0.996), and RSDs were of <3.0% in the precision test and replicate test, with the average recovery rates 95.20%-104.4%, respectively. The results indicatod that the method is simple and accurate, which can be used for the comprehensive quality evaluation of C. paliurus leaf. The established method was applied to determine the contents of 12 batches of C. paliurus leaf from different areas, and the 16 analvtes contents in the samples could be different from several times to dozens times, which indicated that there might be significant quality difference in C. paliurus leaf from different areas.
