ABSTRACT
Objective:To determine the content of albiflorin, paeoniflorin, benzoylpaeoniflorin, sophoricoside, prim-O-glucosylcimifugin, cimifugin, 5-O-methylvisammioside and sec-O-glucosylhamaudol in Huaiqin Salve with high performance liquid chromatography-quantitative analysis of multi-components by single-marker (HPLC-QAMS) method. Methods:The samples were separated with ZORBAX Eclipse XDB-C18 column by a gradient elution using methanol-acetonitrile (1:2) (A)-0.1% phosphoric acid solution (B) as mobile phase and the flow rate was 1.0 ml/min. The detection wavelength was 230 nm for albiflorin, paeoniflorin and benzoylpaeoniflorin, and 254 nm for sophoricoside, prim-O-glucosylcimifugin, cimifugin, 5-O-methylvisammioside and sec-O-glucosylhamaudol. The column temperature was 30 ℃. Using sophoricoside as an internal standard, the relative correction factors (RCFs) of albiflorin, paeoniflorin, benzoylpaeoniflorin, prim-O-glucosylcimifugin, cimifugin, 5-O-methylvisammioside and sec-O-glucosylhamaudol were calculated. The method was validated by comparison of the quantitative results between external standard method (ESM) and HPLC-QAMS method.Results:Albiflorin, paeoniflorin, benzoylpaeoniflorin, sophoricoside, prim-O-glucosylcimifugin, cimifugin, 5-O-methylvisammioside and sec-O-glucosylhamaudol showed good linear relationship within the range of 0.034 7-0.867 5, 0.063 6-1.590 0, 0.006 9-0.172 5, 0.198 6-4.965 0, 0.092 8-2.320 0, 0.026 6-0.665 0, 0.042 7-1.067 5, 0.020 9-0.522 5 μg ( r ≥ 0.999 1); whose average recoveries ( RSDs) were 98.85% (1.02%), 100.04% (0.67%), 96.92% (1.14%), 100.06% (0.85%), 99.31% (1.39%), 99.16% (1.22%), 98.59% (1.33%) and 97.58% (1.41%), respectively. No significant differences were found in the quantitative analysis of the components with ESM and HPLC-QAMS method. Conclusion:The HPLC-QAMS method could provide the reference for themulti-index component evaluation for Huaiqin Salve.
