Abstract:
Orthogonal design was used to study the extraction technology of Qingyan Xiehuo Granule. The solvent volumn, extracting time, extracting times and smashing degree (only for Fructus Canarii) were treated as the factors and examined at various levels. The extraction technology for Folium Polygoni tinctorii and Radix Scutellariae was determined. The methonal extract absorption (at 310nm) of the dried water extract of Folium Polygoni tinctorii and the content of Baicalin were used as the criteria.
