曾采用分光光度法对洋胶滋补口服液中的西洋参总皂甙进行了含量测定,但操作繁琐,实验条件不易控制。改用双波长薄层扫描法对其中含有的人参皂甙Re进行了含量测定,则结果稳定,操作简单。因此,选择此项指标作为洋胶滋补口服液的质量控制指标之一,为其质量标准的制订提供了依据。1 仪器与试剂 日本岛津CS-930型双波长薄层扫描仪、定量毛细管。高效薄层板为青岛海洋化工厂生产。所用试剂均为分析纯。对照品
Spectrophotometry has been used to determine the total saponin of Panax quinquefolium in Yangye Nourishing Oral Liquid, but the operation is cumbersome and the experimental conditions are not easily controlled. The content of ginsenoside Re contained in it was measured using a dual-wavelength thin-layer scanning method. The result was stable and the operation was simple. Therefore, this indicator was selected as one of the quality control indicators for Yangjiao Nourishing Oral Solution, providing a basis for the formulation of its quality standards. 1 Instruments and reagents Shimadzu CS-930 dual wavelength thin-layer scanner, quantitative capillary.
