摘要(Abstract):

目的:建立杀菌止痒洗剂中苦参碱含量的高效液相色谱(HPLC)测定方法,并用此方法对杀菌止痒洗剂进行稳定性考察。方法:采用Diamonsil-C18色谱柱,流动相为乙腈-水-三乙胺(97∶3∶0.2,pH3.5)、检测波长207 nm、流速1.0 mL/min、柱温为25℃,稳定性研究采用加速试验和长期试验。结果:苦参碱在0.081 88~32.752 0μg时与峰面积呈良好的线性关系(r=0.999 9),平均加样回收率为99.2%,RSD=0.69%;杀菌止痒洗剂经过6个月加速实验和12个月长期实验,苦参碱含量无明显变化。结论:所建立的HPLC方法能很好地分离、检测杀菌止痒洗剂中苦参碱,并能评价杀菌止痒洗剂的稳定性。
Objective: To establish HPLC method for determination of matrine in Shajunzhiyang lotion,and determine the stability of the sample.Methods: The HPLC method was carried out on Diamonsil-C 18 column using acetonitrile-water-triethylamine(adjust the pH to 3.5 by phosphoric acid) as mobile phase,and the detection wavelength was 207 nm,the flow rate was 1.0 mL / min and the temperature of column was 25 ℃.The stability of Shajunzhiyang lotion was studied with accelerated test and long-term test.Results: In the results by HPLC method the calibration curve for matrine was linear in the range of 0.081 88 ~ 32.752 0 μg(r = 0.999 9).The average recovery was 99.2%,RSD was 0.69%(n = 6).No significant change of matrine content was found in Shajunzhiyang lotion after 6-month accelerated test and 12-month long-term test.Conclusion: This HPLC method is convenient,precise and reliable for determination of matrine in Shajunzhiyang lotion,and the stability of the lotion is good.
