ABSTRACT
Objective:
On the basis of traditional experience identification,and appearance characteristics and intrinsic index components of Glycyrrhizae Radix et Rhizoma pieces,a comprehensive evaluation was carried out to explore the method of grading Glycyrrhizae Radix et Rhizoma pieces and establish grading standards.Method:
Based on the investigation of 44 batches of Glycyrrhizae Radix et Rhizoma pieces,including their properties,glycyrrhizin content and ammonium glycyrrhizinate content,Glycyrrhizae Radix et Rhizoma pieces were classified according to the market grading to establish the grading standards.Result:
Based on the above data,the Glycyrrhizae Radix et Rhizoma pieces were classified into four grades. First-classaverage diameter>1.66 mm,average weight>0.54 g,glycyrrhizin content>1.10%,glycyrrhizic acid content>2.12%. Second-classthe average diameter is between 1.40-1.66 mm,the average weight is between 0.42-0.54 g,the content of glycyrrhizin is between 0.74%-1.10%,and the content of glycyrrhizic acid is between 1.95%-2.12%. Third-classthe average diameter is between 1.07-1.40 mm,the average weight is between 0.29-0.42 g,the content of glycyrrhizin is between 0.65%-0.74%,and the content of glycyrrhizic acid is between 1.88%-1.95%. Substandardthe average diameterConclusion:
This experiment combines the traditional experience and modern analysis method,in order to develop a scientific,reasonable and accurate classification method.
