To establish a HPLC fingerprint method for the analysis of 7 effective components in Duhuo Jisheng decoction, so as to provide reference for the quality control of Chinese medicinal prescription in Duhuo Jisheng Decoction. Methods:The modern pharmacological research literature of Duhuo Jisheng Decoction was analyzed, the main effective components were screened by HPLC, the chromatographic conditions were established for the determination of the above effective components by HPLC, and the precision, repeatability and sample recovery were investigated. The osthol, dihydrocarvacrol-β-D glucoside, dihydrocarvacrol, paeoniflorin and pinoresinol, β-ecdysterone, ginsenoside R0 in 5 batches of Duhuo Jisheng Decoction were detected. The chromatographic conditions for the determination of the main active ingredients in Duhuojisheng Decoction by HPLC were:odsc18 column (4.6 mm×250 mm, 5 μ m); 1 mL/min; column temperature was 30 ℃, injection volume was 10 μ L; detection method:the detection wavelength was set at 330 nm for 0~40 min and 230 nm for 41~80 min; mobile phase:acetonitrile-0.08% formic acid (a), water-2.5% isopropanol-0.08% formic acid (B) Sequence:0~25 min, 10%~26% mobile phase A, 26~30 min, 27%~44% mobile phase A, 31~35 min, 45%~46% mobile phase A, 41~45 min, 47%~48% mobile phase A; 46~65 min, 49%~92% mobile phase A (2). For 66 to 80 min, 93% to 100% mobile phase A. Results:There was a good linear relationship between osthol, dihydrocarinol-β-D glucoside, dihydrocarinol, paeoniflorin, rosinol diglucoside, β-ecdysterone and ginsenoside R0. The RSDS of precision (intra-day and inter-day) were all lower than 2.5%, and the repeatability RSDS of the 7 components were all lower than 3.5%. The recoveries of 7 components were all ≥95.0%. There were statistically significant differences in the content of 7 ingredients in weight of 5 batches of Duhuo Jisheng Decoction (P<0.05). Conclusion:the main effective components of Duhuo Jisheng Decoction can be quantitatively analyzed by HPLC, but the contents of different kinds of drugs are quite different, which may be related to different decocting people and different batches of Chinese medicinal. |
