Chromatographic Fingerprinting Studies and the Main Ingredient Content Determination of Hypoglycemic and Uric Acid-lowering Active Part of Cyclocarya Paliurus.
This paper carried out the content determination and fingerprinting study of the hypoglycemic and uric acid-lowering active parts of
Cyclocarya paliurus
.(
C. paliurus

paliurus
. herbs from different origins. Under the guidance of activity screening,the extraction conditions were optimized. Using 30% ethanol aqueous solution as extraction solvent,a solid-liquid ratio of 1∶10,and ultrasonic extraction for 1 hour can extract the active part effectively. A high performance liquid chromatography(HPLC) method was used for the determination of the contents of chlorogenic acid,quercetin-3-O-

C. paliurus..
Quality evaluation was based on the content variation of each ingredients with the origin. Among them,the Jiangxi herb S1 had the low content,which differed from the herbs of other origins. At the same time,a fingerprint of the active part of
C. paliurus.
was established. The similarity of the 10 batches of herbs was all greater than 0.9. PCA analysis showed that the quality differences of Jiangxi herb S1,Hunan herbs S6 and S8 were large. The inhibitory activities of
α
-glucosidase and xanthine oxidase showed that Hunan herb S5 had the best hypoglycemic and uric acid-lowering activities,while Jiangxi herb S1 performed poorly,providing consistent conclusions with quality evaluation. The established method provide a scientific basis for the quality control and the quality standard of
