4results about How to "Clear spots" patented technology

The invention relates to a detection method of a medicine for dispelling wind and eliminating dampness. The detection method comprises the following steps: thin-layer identification of a notopterygium root medicinal material, thin-layer identification of a radix angelicae pubescentis medicinal material, thin-layer identification of a radix saposhnikoviae medicinal material, thin-layer identification of ligusticum and ligusticum wallichii medicinal materials, and thin-layer identification of a honey-fried licorice root medicinal material. Through methodological investigation, the detection method has the effects of strong specificity, good durability, clear spots after thin layer expansion, satisfactory separation degree and the like, can effectively control the product quality condition, improves the product quality detection standard, and ensures the product quality.

The application discloses a quality detection method of Yinxie No.1 oral granules, and relates to the field of traditional Chinese medicine analysis. The method adopts a thin layer chromatography method to identify Sophora flavescens, Glycyrrhiza uralensis, Arctium lappa and Saposhnikovia divaricata, and simultaneously adopts a high performance liquid chromatography method to detect the content of paeoniflorin, so that the quality of the Yinxie No.1 oral granules is comprehensively evaluated and controlled, a comprehensive and reliable basis is provided for the authenticity identification and internal quality detection of the granules, and the stability of product quality and the safety and effectiveness of clinical medication are ensured.

The application discloses a quality detection method of three-styrax thin layer chromatography, and relates to the technical field of traditional Chinese medicine preparation quality detection. The active ingredient entering blood and brain is used as a quality control marker, the quality detection index is directly related to the in-vivo pharmacodynamic material basis, the limitation of traditional index only being the in-vitro detectable component is broken, the internal pharmacodynamic quality of the preparation can be more truly reflected, and the scientificity and pertinence of quality control are remarkably improved. Two kinds of different polarity developing agent combinations are constructed, four active components with significant polarity difference, i.e. vanillin, coniferyl aldehyde, glycyrrhizin and glycyrrhizic acid monoammonium salt, are effectively separated on a single thin layer plate through twice up-running development, the technical problems of insufficient separation degree and overlapping of spot tailing of different polarity components in conventional single development are effectively solved through optimization of development distance and developing agent ratio of twice development.

The present application belongs to the technical field of traditional Chinese medicine detection, and particularly relates to a thin-layer identification method of Xuanyu Tongjing pharmaceutical preparation. The present application provides a thin-layer identification method of Xuanyu Tongjing pharmaceutical preparation, comprising the following steps: preparing a test sample solution A, and based on the test sample solution A, using thin-layer chromatography to simultaneously identify gardenia, licorice, white peony root and cortex moutan in the Xuanyu Tongjing pharmaceutical preparation; according to the thin-layer chromatography: taking the test sample solution A, a control medicinal solution and a control sample solution, respectively spotting on the same silica gel thin-layer plate, and using a volume ratio of ethyl acetate, formic acid, glacial acetic acid and water as 15:(1-3):(1-3):2 as a developing agent for development. The thin-layer identification method can simultaneously detect the licorice, gardenia, white peony root and cortex moutan components in the Xuanyu Tongjing pharmaceutical preparation, and has short detection time and high efficiency.
