摘要
本文报道了分别用高氯酸—香兰醛和浓硫酸比色法测定几种新型的人参保健食品中人参总皂甙的含量。通过对其显色机理及干扰试验结果的分析,探讨了这两种方法的适应范围。结果表明,高氯酸—香兰醛比色法适用于各种人参制品中总皂甙的含量的测定,而浓硫酸比色法的局限性较大。
A colorimetric method for the determination of total Ginsenoside in several kinds of Ginseng products used vanilla-perchloric acid and concentrated sulfuric acid as color reagent respectively was described and evaluated. The suitability of the two color reagents was disscused on the basis of the color-producing mechanism and interference tests. The results showed that the colorimetric method which vanilla-perchloric acid used as color reagent was suitable for all kinds of Ginseng products, while concentrated sulfuric acid as color reagent was rather limited and was only suitable for those with little saccharides. The method presented can be used to routine analysis and applied to evaluate the quality of Ginseng products.
