Abstract
Objective To establish a high performance liquid chromatography(HPLC)characteristic chromatogram and multi-component content determination method for the substance benchmark of Fuzi Decoction.Methods The characteristic chromatogram method of Fuzi Decoction substance benchmark was established,and the Similarity Evaluation System of Chromatographic Fingerprint of Traditional Chinese Medicine(2012 Edition)was used to analyze the characteristic chromatograms of 15 batches of Fuzi Decoction substance benchmark samples.The HPLC content determination methods of 1 1 components in the Fuzi Decoction substance benchmark samples were established respectively,and the dry extract rate of 15 batches of Fuzi Decoction substance benchmark samples was determined.Results The similarity of characteristic chromatograms of 15 batches of Fuzi Decoction substance benchmark samples was greater than 0.9,and 12 common peaks were selected and eight of them were identified.The results showed that the contents of benzoylmesaconine,benzoylhypaconine,atractylenolide Ⅲ,ginsenoside Rg1,ginsenoside Re,ginsenoside Rb1,gallic acid,albiflorin,paeoniflorin,1,2,3,4,6-penta-galloyl glucose and benzoyl paeoniflorin were 0.050 3-0.191 1,0.026 7-0.047 0,0.043 0-0.127 6,0.554 6-1.006 8,0.568 7-0.979 5,0.929 9-1.726 1,1.058 9-2.118 4,1.430 3-4.965 5,6.882 9-9.511 1,0.056 1-0.262 5,0.160 6-0.369 0 mg/g,respectively.The average dry extract rate of the 15 batches of Fuzi Decoction substance benchmark samples was 29.54％.Conclusion The established characteristic chromatogram and multi-index content determination method are accurate and stable,which provides a basis for the quality control of the substance benchmark and related preparations of Fuzi Decoction.
