Abstract:
Objective:Through the analysis of the characteristics and main chemical components of Ginseng Radix et Rhizoma,the correlation between the characteristics and components of Ginseng Radix et Rhizoma was explored,and a new evaluation standard of Ginseng Radix et Rhizoma grade was established to provide a more comprehensive and scientific basis for the quality evaluation of Ginseng Radix et Rhizoma. Method:The appearance characteristics of 48 batches of Ginseng Radix et Rhizoma samples were quantitatively measured. The contents of 9 kinds of Ginseng Radix et Rhizoma were determined. The results of correlation analysis,principal component analysis and cluster analysis were used to classify ginseng medicinal materials according to the analysis results,and the grade evaluation criteria were constructed. Result:First-class ginseng medicinal materials:diameter of main root>1.72 cm,length of reed head>2.61 cm,weight of single branch>14.15 g,content of ginsenoside Rb1>0.612 1%,content of ginsenoside Re>0.385 8%,content of ginsenoside Rg1>0.320 8%,no scar,impurities,moth,mildew. Second-class ginseng medicinal materials:the diameter of main root is 1.55-1.72 cm,the length of reed head is 1.74-2.61 cm,the weight of single branch is 10.24-14.15 g,the content of ginsenoside Rb1 is 0.496 8%-0.612 1%,the content of ginsenoside Re is 0.323 3%-0.385 8%,the content of ginsenoside Rg1 is 0.263 6%-0.320 8%,and there are no scars,impurities,worms and mildew. Third-class ginseng medicinal materials:main root diameter 1.29-1.55 cm,reed head length 1.34-1.74 cm,single branch weight 6.90-10.24 g,ginsenoside Rb1 content 0.389 5%-0.496 8%,ginsenoside Re content 0.235 2%-0.323 3%,ginsenoside Rg1 content 0.217 1%-0.263 6%,no impurities,worms,mildew. Fourth-class ginseng medicinal materials:diameter of main root<1.29 cm,length of reed head<1.34 cm,weight of single branch<6.90 g,content of ginsenoside Rb1<0.389 5%,the content of ginsenoside Re<0.235 2%,content of ginsenoside Rg1<0.217 1%,without impurities,worms and mildew. Conclusion:The appearance indexes of ginseng medicinal materials were divided according to the standards of taproot diameter,reed head length and single ginseng weight,and the content of ginsenoside Rg1,Re,Rb1 was used as the internal quality evaluation index. Ginseng commercial specifications were divided into four grades,which integrated the appearance and internal indicators,and had more scientific and comprehensive characteristics,which could be used as the basis for the classification of Ginseng Radix et Rhizoma medicinal materials.
