  • Method for identification of characteristic components in Kai-Xin-San by thin-layer chromatography (TLC)
    Patent number: 12292426
    Abstract: A method for identification of characteristic components in a Kai-Xin-San by thin-layer chromatography (TLC) is provided, belonging to the technical field of pharmaceutical raw material detection and traditional Chinese medicine quality control. The method only needs to prepare two test solutions to simultaneously identify six characteristic components in the Kai-Xin-San, namely ginsenoside Rb1, ginsenoside Re, tenuifolin, ?-asarone, dehydrotumulosic acid, and pachymic acid. An automatic TLC spotting instrument can ensure even sampling and flat chromatographic bands and the silica gel G thin-layer plates after spotting are placed in the steam of the optimized developing solvent to allow pre-saturation.
