摘要: 建立了能同时分离检测何首乌中二苯乙烯苷与大黄素、芦荟大黄素、大黄酸、大黄酚、大黄素甲醚5 种蒽醌类成分的胶束电动毛细管色谱法.考察了缓冲液pH 值、十二烷基硫酸钠( SDS) 浓度、硼砂浓度、甲醇浓度和运行电压对分离检测的影响,获得最佳的分离检测条件: 缓冲液由15mmol /L 硼砂、30mmol /L SDS 和10%甲醇组成,pH 值为9.6,运行电压为25 kV.在此条件下,二苯乙烯苷和5 种蒽醌类成分在18min 内得以完全分离,迁移时间和峰面积的相对标准偏差分别为1.06% ~ 1.61%和1.46% ~ 2. 87%,检出限为0.26 ~ 0.56mg /L,回收率为97.2% ~ 103.2%.

Abstract:

In this investigation,a method of using the micellar electrokinetic chromatography was laid down for the simultaneous determination of stilbene glucoside and five anthraquinones,including emodin,aloe-emodin,rhein,chrysophanol and physcion,in Polygonum multiflorum Thunb.,and the effects of the buffer solution pH value,the SDS concentration,the sodium tetraborate concentration,the methanol volume fraction and the operating voltage on
the separation and determination were discussed. The results show that optimal separation and determination conditions are an operating voltage of 25 kV and a buffer solution with a pH value of 9.6,15mmol /L of sodium tetraborate,30mmol /L of SDS and 10%( volume fraction) of methanol,and that, in the optimal conditions,stilbene glucoside and the five anthraquinones are completely separated within 18minutes,with a relative standard deviation of migration times of 1.06% ~ 1.61%,a relative standard deviation of peak areas of 1.46% ~ 2.87%,a detection limit of 0.26 ~ 0.56mg /L and a recovery of 97.2% ~ 103.2%.
