建立了毛细管GC法测定麝香壮骨膏中樟脑、薄荷脑、冰片、水杨酸甲酯的含量测定方法。采用DB-WAX毛细管柱,FID检测器,挥发油提取法净化样品,乙酸乙酯为稀释溶剂。樟脑平均回收率96.5%;RSD为1.4%、薄荷脑平均回收率97.0%;RSD为1.1%、冰片平均回收率96.7%;RSD为1.6%;水杨酸甲酯平均回收率96.8%;RSD1.1%。结论该方法简单、准确、重复性好,为冠心膏的质量控制提高提供了依据。
A capillary GC method was established for the determination of camphor, menthol, borneol and methyl salicylate in musk Zhuanggu cream. DB-WAX capillary column, FID detector, volatile oil extraction method to purify the sample, ethyl acetate as a dilute solvent. The average recovery of camphor was 96.5%. The RSD was 1.4%. The average recovery of menthol was 97.0%. The RSD was 1.1%. The average recovery of borneol was 96.7%. The RSD was 1.6%. The average recovery of methyl salicylate was 96.8%. 1%. Conclusion The method is simple, accurate, reproducible and provides the basis for the quality control of Guanxin Paste.
