Ke-xin WEI, Yun-long GUO, Na-wen SHI, et al. Grade Standard of Ginseng Radix et Rhizoma[J]. Chinese journal of experimental traditional medical formulae, 2019, 25(11): 145-153. DOI: 10.13422/j.cnki.syfjx.20191115.
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:
2
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:
2

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 Rb
1
is 0.496 8%-0.612 1%
the content of ginsenoside Re is 0.323 3%-0.385 8%

Conclusion:
2
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 Rg
1
Re
Rb
1
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.
