【摘要】 目的建立GC法同步测定通络祛痛膏中樟脑、薄荷脑、龙脑等3种成分含量。方法使用气相色谱仪(岛津GC-2014),DB-WAX毛细管柱(30 m×0.25 mm×0.50μm)。以氮气为载气,FID检测器,柱温140℃,内标法测定样品中3种成分的含量。结果通络祛痛膏中樟脑、薄荷脑和龙脑及内标物萘等4种物质在同一色谱条件下获得良好分离;樟脑、薄荷脑、龙脑的回收率分别为98.76%(RSD=0.60%),97.48%(RSD=0.66%),100.99%(RSD=0.65%)。采用此法对10批样品进行含量测定,均取得了满意的结果。结论该方法简便、准确,分离度好,可用于控制通络祛痛膏的质量。更多还原

【Abstract】 Objective To establish a method for simultaneous determination of camphol,menthol crystal and camphor in Tongluo Qutong Gao. Methods Naphthalene was used as the internal standard. DB-WAX capillary column was adopted,nitrogen as the carrier gas,and FID as the detector. The column temperature at 140℃. Results Camphol,menthol crystal and camphor in Tongluo Qutong Gao and naphthalene have been separated well. The average recovery rates of camphor,menthol crystal and camphol were 98. 76%(RSD =0. 66%),97. 48%(RSD =0. 66%) and 100. 99%(RSD =1. 4%),respectively. Conclusion The method is simple,accurate and separable,and it can also be used to control the quality of Tongluo Qutong Gao.更多还原
