[0019] Take tracheitis pill products for quality standard test
[0020] The thin-layer identification of Scutellaria baicalensis was compared with the reference substance of baicalin and the negative control sample of Scutellaria baicalensis. The color was developed under ultraviolet light (365nm) and sprayed with 1% ferric chloride ethanol solution. In the chromatogram of the test substance, spots of the same color appear in the corresponding position of the chromatogram of the reference substance, and the color is clear and the specificity is strong. Be adopted. Baicalin reference substance 715-9204 China National Institute for the Control of Pharmaceutical and Biological Products.
