ABSTRACT
Objective To establish a method of GC for determination of Waishang Ruyi Ointments.Methods WAX PEG-20M capillary column was used.The column temperature was 140 ℃,the injection port temperature was 230 ℃,the detector temperature was 250 ℃,the flow rate was 1.0 mL/min.Results For Waishang Ruyi Ointments,the linear range was 0.513 8～5.138 mg,and the average recovery rate was 96.2% with RSD=1.0%.Conclusion The method is simple,easy-to-use,and can effectively control the quality of the ointments.
ABSTRACT
Objective To establish a method for the fake indentification of Fengliaoxing Fengshi Dieda medicinal wines by TLC and GC. Methods The column was Supelco SE-30 (30 m?0.25 mm?0.25 ?m). The flow rate was 1.4 mL/min, and gas was N2. The inlets temperature was 210 ℃;the detectors temperature was 300 ℃;the column temperature use program rising temperature. Results TLC can identify whether ephedra and erycibe were contained in the medicinal wines. GC can identify whether diclofenac sodium was contained in the medicinal wines. Conclusion The method is accurate and reproducible, and can be used for the identification of Fengliaoxing Fengshi Dieda medicinal wines.
