摘要
目的 制备了丹参酮ⅡA亚微乳,进行HPLC法测定.方法 两步高压乳匀法制备丹参酮ⅡA亚微乳,使用c18柱,以乙腈:水(80:20)为流动相,检测波长270nm,建立HPLC法测定丹参酮ⅡA亚微乳的含量.结果 研制的亚微乳平均粒径为(191.3±0.56)nm,Zeta电位为(41.76±0.31) mV.丹参酮ⅡA在0.25~4mg/ml浓度范围内存在良好的线性关系(r=0.9999),三个浓度样品的回收率分别为(99.74±0.78)、(100.53±1.25)、(99.11±0.60),日内和日间RSD分别为1.76%、0.79%、0.75%和1.93%、1.50%、0.68%.结论
Objective To determine the content of tanshinone lI A submicron emulsion by HPLC. Methods The 2 steps of high pressure homogenization preparation of tanshinone Ⅱ A submicron emulsion was using C18 column, acetonitrile: water (80: 20) as the mobile phase. The detection wavelength was 270nm. The content determination of tanshinone Ⅱ A submicron emulsion would be established by HPLC method. Results The average particle size of submicron emulsion was ( 191.3 ± 0. 56) nm, Zeta potential was (41.76 ± 0. 31 ) inV. Tanshinone II A in 0. 25 - 4mg' ml concentration range of memory in a good linear relationship ( r = 0. 9999) , recovery of the three samples were (99.74 ± 0.78) , (100. 53± 1.25) , (99. 11 ±0.60) , the intra-day and inter-day RSD were 1.76% , 0.79% , 0. 75% and 1.93% , 1.50% , 0. 68%. Conclusion Tanshinone Ⅱ A submieron emulsion was stable.
