Abstract:
Objective To establish the method for simultaneous determination of six index components in the water extract of Weile Prescription;To optimize the water extraction process.Methods UPLC-MS/MS was used with Waters CORTECS C18 column(2.1 mm×100 mm,1.6 μm)as the chromatographic conditions;the mobile phase was 0.1%formic acid water-acetonitrile with gradient elution;the flow rate was 0.25 mL/min;the column temperature was 40℃;the sample volume was 2 μL.Electrospray negative ion source,positive and negative ion switching multi-reaction monitoring(MRM)mode were detected.Taking the content of six index components(gallic acid,vitexin,paeoniflorin,naringin,hesperidin and glycyrrhizic acid)and extraction rate as evaluation indexes,the weight coefficient of each index was determined by G1-entropy weight method,and the optimum parameters of extraction process were determined by orthogonal experiment design with the amount of water,extraction time and extraction times as investigation factors.Results There was a good linear relationship of the six components in the water extract of Weile Prescription in the concentration range(r>0.999),and the average recovery rate was 96.83%-102.56%,RSD<4.0%.The best technological parameters were as follows:Chinese decoction pieces were soaked in 12 times of water for 2 h,and extracted twice,each time for 1.5 h.Conclusion The UPLC-MS/MS method established in the study for simultaneous determination of six components in Weile Prescription is rapid,simple and sensitive,and the optimized extraction process is stable and feasible,which provides experimental basis for the development and research of the preparation.
