[摘要]目的: 为复方毛冬青注射液建立专属性含量测定方法。 方法: 采用气相色谱法对甲基正壬酮进行含量测定。色谱柱:HP-1(Aglient19091z-413，30m×320μm×0.25μm);氮气为9.23psi，流量1.8mL.min;空气400mL.min;氢气40mL.min;柱温80℃(2min)至220℃，升温速率为15℃.min;再升至270℃(13.75min)，升温速率为40℃.min;汽化室240℃;检测室280℃;进样量1μL;检测器为FID。 结果: 线性范围为1.0～20.0μg.mL，平均回收率为99.05%，RSD=1.29%(n=6)。 结论: 本法操作简单、可靠、具有实用性。
