Systematic Analysis Of Huangqin Seeds And Its Adulterants

Huangqin is drying roots of Scutellaria baicalensis Georgi. There are many other kinds of huangqin in Heibei such as Scutellaria viscidula Bge., Scutellaria scordifolia Fisch ex Schrank, Scutellaria strigillosa Hemsl and Scutellaria pekinensis Maxim. At present the materials mainly come from cultivation, it's necessary to identify seeds of Huangqin and its adulterants. Since the five kinds of plant belong to the same species, their seeds are similar in macroscopical characters. We identify them by their Macroscopic Characters, Microscopical Features, Physical-chemical Characters and by molecular biology technology. Through experiments we can prevent planting Adulterants and choose better variety of Huangqin. The methods are established. It is not only a basic applying but also a deep study .We can establish standards for identification of Huangqin.1 Identification from Macroscopic Characters, Microscopical Features and Physical-chemical CharactersObjective: To establish identification standards for Huangqin and its adulterants from their appearance characters, microscopical features and physical-chemical characters with fast, simple, feasible methods.
