[Objectives]To regulate the quality of Wanjinxiang Shushuang Ointment through simultaneously quantifying menthol,camphor,1,8-cineole,linalool,borneol and caryophyllene oxide by QAMS(quantitative analysis of multi-components by single-marker).[Methods]The method was performed using an Agilent DB-WAX(30 m×0.32 mm,0.25μm)polyethylene glycol chromatographic column;with nitrogen employed as a carrier gas.The constant pressure was 4.73 psi;and the injection temperature was 240℃,with a shunt ratio:of 10:1;The hydrogen flame ion detector with a detector temperature of 240℃;the injection volume was 0.3μL.To verify the accuracy and applicability of QAMS,the results were compared with those obtained using the internal standard method(naphthalene).[Results]In Wanjinxiang Shushuang Ointment,menthol,camphor,1,8-cineole,linalool,borneol,caryophyllene oxide and naphthalene were well separated by the same chromatography with good linearity in their respective ranges(R≥0.9992).The average recoveries were 99.66%,101.03%,98.07%,98.24%,101.39%,and 103.39%with RSD s of 0.69%,1.52%,1.25%,1.94%,1.44%,and 2.74%,respectively.The QAMS is similar to the internal standard method.[Conclusions]This simple,accurate method with high precision,separation and reproducibility can serve as a reference for the quality control of Wanjinxiang Shushuang Ointment. 展开更多
