Study on Quality Difference Analysis of Scutellaria Baicalensis Decoction Pieces with Processed Products
Comparison of quality differences between raw Scutellaria baicalensis decoction pieces and 8 different processed products.Pro-cess the slices of Scutellaria baicalensis in sequence using stir frying,charring,charcoal frying,earth frying,wine frying,vinegar frying,ginger frying,and salt frying methods.Microscopic observation and thin layer identification of raw and processed Scutellaria baicalensis decoction pieces,and measure the content of extracts and total flavonoids separately.In microscopic identification,the characteristics of stone cells,phloem fibers,and wood fibers in raw Scutellaria baicalensis,fried Scutellaria baicalensis,roasted Scutellaria baicalensis,vin-egar Scutellaria baicalensis,wine Scutellaria baicalensis,salt Scutellaria baicalensis,and ginger Scutellaria baicalensis are clearly visible,the wall and pore groove phenomena of stone cells,wood fibers,and phloem fibers in Scutellaria baicalensis charcoal are not obvious.In thin layer identification,the reference materials of Scutellaria baicalensis,baicalin,baicalin,and Hanbaicalin,as well as the test samples,have clear spots and good separation.The order of the content of alcohol soluble extracts from high to low is as follows:raw Scutellaria ba-icalensis＞roasted Scutellaria baicalensis＞roasted Scutellaria baicalensis＞soil Scutellaria baicalensis＞vinegar Scutellaria baicalen-sis＞wine Scutellaria baicalensis＞salt Scutellaria baicalensis＞ginger Scutellaria baicalensis＞charcoal Scutellaria baicalensis.The order of total flavonoid content from high to low is as follows:soil fried Scutellaria baicalensis＞roasted Scutellaria baicalensis＞fried Scutellaria baicalensis＞vinegar Scutellaria baicalensis＞wine Scutellaria baicalensis＞salt Scutellaria baicalensis＞raw Scutellaria baicalensis＞ginger Scutellaria baicalensis＞Scutellaria baicalensis charcoal.The influence of different processing methods on the qual-ity of Scutellaria baicalensis decoction pieces,the method is simple and feasible,it can lay the foundation for the expanded application and quality evaluation of Huangqin processed decoction pieces.
