采用HPLC法测定骨刺消痛液中麻黄碱含量 ,在C 18反相柱以乙腈 水 磷酸 三乙胺为流动相 ,用外标法测定麻黄碱含量 ,结果在 0～ 1 8775mg范围内与色谱峰面积呈线形关系 ,加样回收率为 10 0 0 9% ,RSD % =0 35。该法可靠、专属性强、灵敏度高。
HPLC method was used to determine the content of ephedrine in bone pain relief solution. Acetonitrile phosphate triethylamine was used as the mobile phase on C 18 reversed-phase column. The content of ephedrine was determined by external standard method. The results were in the range of 0 to 18,775 mg and the chromatographic peaks. The area was linear and the recovery was 100.09% with RSD % =0 35. This method is reliable, highly specialized, and highly sensitive.
