摘要
目的测定丙泊酚纳米注射液的溶血磷脂含量及体外溶血性。方法建立HPLC测定溶血磷脂的方法,色谱柱为Plati-sil C18(4.6 mm×250 mm,5μm);流动相A为乙腈-水(9∶1),流动相B体积分数为0.2%磷酸水溶液(三乙胺调节pH至2.5),线性梯度洗脱:0 min,60%A;15 min,60%A;16 min,90%A;22 min,90%A;23 min,60%A;35 min,60%A;流速为1.2 mL.min-1;柱温为30℃;检测波长为210 nm;使用分光光度法测定体外溶血百分率。结果溶血磷脂在19.8～198.0μg.mL-1内与其峰面积成良好的线性关系(r=0.999 8),平均回收率为102.0%,RSD为0.63%(n=9),3批样品溶血磷脂含量分别为0.313,0.273,0.318 mg.mL-1;3批样品溶血百分率分别为2.70%,3.37%,3.04%。结论本方法可用于丙泊酚纳米注射液中溶血磷脂的含量测定;3批样品溶血百分率均小于5%。
OBJECTIVE To determine lysolecithin and in vitro hemolysis of propofol nano-injection. METHODS An HPLC method was established for determination of lysolecithin. The sample was analyzed with a Platisil ClS column （4. 6 mm × 250 mm, 5 μm） at 30 ~C. Mobil phase A was acetonitrile-water （9：1 ）. Mobil phase B was 0. 2% phosphoric acid aqueous solution （pH adjusted to 2. 5 with triethylamine）. Gradient elution program was used as follows： 0 min, 60% A; 15 min, 60% A; 16 min, 90% A; 22 min, 90% A; 23 min, 60% A; 35 min, 60% A. The flow rate was 1.2 mL · min^-1. The detection wave length was set at 210 nm. Spectrophotometric method was used to determine hemolysis. RESULTS The linear range of the calibration curve for lysolecithin was 19. 8 - 198. 0 μg·mL^-1 （r = 0. 999 8）. The average recovery was 102. 0% and RSD was 0. 63% （n =9）. The lysolecithin contents of three batches of samples were 0. 313, 0. 273 and 0. 318 mg·mL^-1, respectively. The hemolysis rates were 2. 70%, 3.37% and 3.04%, respectively. CONCLUSION The HPLC method can be used for the determination of lysolecithin in propofol nano-injection. The hemolysis rates of three batches of samples were less than 5%.
