【摘要】 目的 探讨高效液相色谱法(high performance liquid chromatography,HPLC)测定复方维生素注射液A、E、K1含量的可行性。方法 采用HPLC法，C18色谱柱(150 mm×46 mm,5 μm)，流动相：甲醇-酒精(80∶20)，检测波长270 nm。结果 维生素A棕榈酸酯在125~125．5 μg/ml之间线性良好(r=0．999 9),平均回收率为99．38%，RSD为1．36%；
维生素E在125~125．5 μg/ml之间线性良好（r=0．999 9）,平均回收率为95．87%，RSD为0．95%。维生素K1在16．5~166．5 μg/m之间线性良好(r=0．999 8)，平均回收率为98．08%，RSD为1．57%。结论 HPLC法测定复方维生素注射液维生素A、E、K1的含量专属性强，灵敏度高，准确性好。

【Abstract】 Objective To determine the contents in compound vitamins A、E、K1 injection by high performance liquid chromatography(HPLC).Methods HPLC was used C18column(150 mm×46 mm,5 μm)was selected,the mobile phase was methanol-alcohol(80∶20).Detection was performed by UV with wavelength of 270 nm.Results A linearity of retinyl palmitate was obtained from 125 to 125．5 μg/ml with good correlation(r=0．999 9).The average recovery of retinyl palmitate was 99．38%,and RSD Was 1．36%.A linearity of vitamin E was obtained from 125 to 1251 μg/mlwith good correlation(r=0．999 8).The average recovery of vitamin E was 98．87%,and RSD was 0．95%.A linearity of vitamin K1 was obtained from 16．5 to 166．5 μg/ml with good correlation(r=0．999).The average recovery of vitamin K1 was 98．08%,and RSD was 1．57%.Conclusion The RP-HPLC is sensitive and accurate in determining thecontents in compound vitamin injection.
