Problems solved by technology

The TLC identification item of the current quality standard used the control medicinal material of Paitanchichi, but no investigation was carried out on its counterfeit and mixed products. On the corresponding position of the chromatogram of the reference medicinal material, there are almost the same spots and fluorescent spots, and the chromatograms of the reference medicinal material of Panax notoginseng and Shuitianqi are also highly similar, lacking specificity, see the appendix of the description of the present invention Figure 14 , can not effectively distinguish the seven medicinal materials from the paddy fields and their easily mixed products; and the existing standards do not establish content determination items, and cannot effectively control the overall quality of the seven medicinal materials from the paddy field

Abstract

The invention discloses a quality detection method of a lobedfruit schizocapsa herb medicinal material. The quality detection method comprises a thin-layer chromatography identification method of the lobedfruit schizocapsa herb medicinal material and a content determination method of root tuber ketolactone A in the lobedfruit schizocapsa herb medicinal material. The thin-layer chromatography identification method for the lobedfruit schizocapsa herb has the characteristics of high sensitivity, strong specificity, good separation effect and the like, is simple, convenient and feasible, has strong reproducibility, and can be used for accurately identifying the authenticity of the lobedfruit schizocapsa herb; according to the method for determining the content of the root tuber ketolide A in the lobedfruit schizocapsa herb medicinal material, the content of the root tuber ketolide A in the lobedfruit schizocapsa herb medicinal material can be accurately and quickly determined, and an effective qualitative and quantitative analysis means is provided for the lobedfruit schizocapsa herb medicinal material, so that the quality of the lobedfruit schizocapsa herb medicinal material is favorably monitored. By adopting the quality detection method for the lobedfruit schizocapsa herb, the overall quality of the lobedfruit schizocapsa herb can be effectively controlled, and the safety and effectiveness of clinical medication of the lobedfruit schizocapsa herb are ensured.
