摘    要:目的:建立同时测定紫草凡士林中紫草素、乙酰紫草素、乙酰氧基异戊酰紫草素、异丁酰紫草素和β,β’-二甲基丙烯酰紫草素含量的方法。方法:采用高效液相色谱法。色谱柱为AgilentEclipseXDB.C18(250mm×4.6mm,5um),流动相为甲醇.乙腈-0.2%甲酸溶液(48:32:20,V/V/V),流速为1.0ml/min,柱温为24℃,检测波长为516nln。结果:紫草素、乙酰紫草素、乙酰氧基异戊酰紫草素、异丁酰紫草素和β,β’-二甲基丙烯酰紫草素的质量浓度分别在7.12~71.20μg/ml(r=O.9994)、11.92~119.20μg/ml(r=0.9996)、4.07~40.70μg/ml(r=0.9997)、3.65~36.50μg/ml(r=0.9996)、5.11~51.10ug/m1(r=0.9995)范围内与各自峰面积积分值呈良好的线性关系;平均加样回收率分别为100.82%、101.49%、97.99%、100.29%、101.74%,RSD分别为3.03%、1.25%、1.75%、2.25%、2.31%(”均为6)。结论:该方法简单易行、结果准确、重复性好,适用于紫草凡士林的质量控制。

Abstract:OBJECTIVE: To develop a method for simultaneous determination of shikonin, acetylshikonin,fl-acetoxyisovaleryl- shikonin, isobutylshikonin and β,β'-dimethylacrylshikonin in Zicao vaseline. METHODS: HPLC method was adopted. The separa- tion was carried out on an Agilent Eclipse XDB-C18(250 mm×4.6 mm, 5 μm) column with mobile phase consisted of methanol-ace- tonitrile-0.2% formic acid(48 : 32 : 20, V/F/F) at the flow rate of 1.0 ml/min. The detection wavelength was set at 516 nm and the column temperature was 24 OE. RESULTS: The linear ranges of shikonin, acetylshikonin,fl-acetoxyisovalerylshikonin, isobutylshi- konin and β,β'-dimethylacrylshikonin were 7.12-71.20 μg/ml(r=0.999 4), 11.92-119.20 μg/ml(r=0.999 6),4.07-40.70 μg/ml(r= 0.999 7), 3.65-36.50 μg/ml(r=0,999 6) and 5.11-51.10 μg/ml(r=0.999 5), respectively. The average recoveries were 100.82% (RSD=3.03% ,n=6 ) 101.49% (RSD=1.25% ,n=6 ) ,97.99% (RSD=1.75% ,n=6 ) ,100.29% (RSD=2.25% n=6 )and 101.74% (RSD = 2.31%, n=6). CONCLUSIONS: This method is simple, feasible, accurate and reproducible. It can be used for quality con- trol of Zicao vaseline.
