A procedure was developed for the determination of low levels of the anthraquinones aloe-emodin and aloin A (barbalin) in aloe products based on gas chromatography/mass spectrometry (GC/MS) of the trimethyl silyl (TMS) derivatives of these analytes in the presence of Chrysophanol used as internal standard. The method was used to analyze several aloe based commercial products (liquids, gels and solids). Wide variation in the level of these anthraquinones was observed among the different products. The method had a sensitivity of 0.005 ppm of aloe-emodin and 0.05 ppm of aloin.
开发了一种基于气相色谱/质谱联用(GC/MS)的方法,用于测定芦荟产品中痕量的蒽醌类物质芦荟大黄素和芦荟苷A(巴巴林)。该方法通过在作为内标的大黄酚存在下,对这些分析物的三甲基硅烷基(TMS)衍生物进行GC/MS分析。此方法用于分析几种基于芦荟的商业产品(液体、凝胶和固体)。结果发现,不同产品中这些蒽醌类物质的含量差异很大。该方法对芦荟大黄素的检测限为0.005 ppm,对芦荟苷的检测限为0.05 ppm。
