Analysis on Quality Difference of Chuanxiong Chatiao San and Chuanxiong Chatiao Granules Based on Anti-platelet Aggregation Activity and Fingerprint
Objective To establish the HPLC fingerprint of Chuanxiong Chatiao San(CXCTS)and Chuanxiong Chatiao Granules(CXCTG),and to compare their quality difference by using HPLC fingerprint in combination with anti-platelet aggregation activity in vitro.This study explores the material basis of anti-platelet aggregation activity of CXCTS and CXCTG to provide a reference for the quality control and clinical application.Methods HPLC fingerprint for 20 batches of CXCTS and seven batches of CXCTG were established,and systematic clustering analysis was conducted using SPSS 27.00 statistical software.In addition,the in vitro anti-platelet aggregation activity was determined.The relationship between HPLC fingerprint spectrums and anti-platelet aggregation activity was analyzed by using SIMCA P-14.0 statistical software for partial least squares analysis(PLS).The markers of quality difference of CXCTS and CXCTG were screened.Results A total of 26 common peaks in the fingerprint and 16 components were identified.Systematic clustering analysis showed that CXCTS and CXCTG were clustered into two categories.There were significantly differences in HPLC fingerprint and anti-platelet aggregation activity between CXCTS and CXCTG.Combining correlation coefficient and VIP value,we confirmed 17 common peaks,which showed positive correlation with anti-platelet aggregation activity and the VIP values were greater than one.The effective fractions of anti-platelet aggregation activity were screened out.Among the above-mentioned fractions,hesperidin,rosmarinic acid,buddleoside,pulegone,coniferyl ferulate,(Z)-ligustilide,notopterol,imperatorin,isoimperatorin,peak 7,9,12,14,6,17,19,and 23 were picked out as the quality difference markers.Conclusion HPLC fingerprint spectrum of CXCTS and CXCTG was established in this study.The established method can detect multiple active components in both formulations.There was significant difference between CXCTS and CXCTG on the content of active ingredients and anti-platelet aggregation activity.The former is of higher quality than the latter.This study can provide reference for the quality control and clinical application of CXCTS and CXCTG.
