Abstract:
AIM To invesigate the quantitative transmitting rules of benchmark samples of Ganjiang Lingzhu Decoction.METHODS HPLC fingerprints were established,after which principal component analysis and partial least squares discriminant analysis were performed.The contents of 6-gingerol,liquiritin and glycyrrhizic acid were determined,after which their transfer rates and dry paste rate were calculated.RESULTS There were 22 common peaks in the fingerprints for 15 batches of benchmark samples with the similarities of more than 0.9.Various batches of benchmark samples were clustered into 3 categories,4 principal components demonstrated the accumulative variance contribution rate of 92.676％,and liquiritin made a great contribution to grouping.In various batches of medicinal materials-decoction pieces,decoction pieces-standard decoctions and standard decoctions-benchmark samples,the transfer rates of 6-gingerol were 84.72％-100.00％,14.29％-24.14％,88.60％-99.36％,those of liquiritin were 74.38％-100.00％,38.54％-64.20％,96.91％-100.30％,and those of glycyrrhizic acid were 68.28％-103.27％,28.48％-49.79％,92.93％-100.49％,the dry paste rate was 13.75％-16.41％.CONCLUSION The preparation process for benchmark samples of Ganjiang Lingzhu Decoction is stable,6-gingerol,liquiritin and glycyrrhizic acid can be taken as their quality markers.Fingerprint combined with content determination can provides a reference for the quality control of Ganjiang Lingzhu Decoction and their related preparations.
