For the first time, a sensitive reversed-phase HPLC electrochemical array method has been developed for the quantitative analysis of 8 major ginger components ([6]-, [8]-, and [10]-gingerol, [6]-, [8]-, and [10]-shogaol, [6]-paradol, and [1]-dehydrogingerdione) in 11 ginger-containing commercial products. This method was valid with unrivaled sensitivity as low as 7.3-20.2 pg of limit of detection and a range of 14.5-40.4 pg for the limit of quantification. The levels of 8 ginger components in 11 different commercial products were quantified by use of this method. The results found that both levels and ratios among the 8 compounds vary greatly in commercial products.
首次建立了一种灵敏的反相高效液相色谱电化学阵列法，用于定量分析 11 种含姜商业产品中的 8 种主要姜成分（[6]-、[8]-和[10]-姜醇、[6]-、[8]-和[10]-姜烯酚、[6]-对丙烯基酚和[1]-脱氢姜二酮）。该方法具有无与伦比的灵敏度，检测限低至 7.3-20.2pg，定量限范围为 14.5-40.4pg。使用该方法定量测定了 11 种不同商业产品中 8 种姜成分的含量。结果发现，商业产品中 8 种化合物的含量和比例差异很大。
