Comprehensive quality evaluation of Panax Notoginseng(Burk.)F.H.Chen from different producing areas by entropy weight and grey incidence degree method
Objective:To evaluate the quality of Panax Notoginseng(Burk.)F.H.Chen from different producing areas by entropy weight and grey incidence degree method.Methods:The contents of extracts,total flavonoids,total polysaccharides,total saponins and five kinds of saponins in 16 batches from Yunnan,Guizhou,Guangxi and Sichuan were determined.The weight obtained by entropy weight method was used as the resolution coefficient(ρ),The quality evaluation model was established by using grey incidence degree method.Results:The samples from all producing areas were in conformity with the standard of 2020 Chinese Pharmacopoeia,and the amplification producing areas was scientific.The comprehensive evaluation results showed that the relative correlation degree ranged from 0.286 to 0.645,and the quality showed a trend of traditional production areas＞new production areas.Conclusion:The evaluation model established by entropy weight method combined with grey incidence degree method is reliable and can provide reference for the quality control and resource development of Panax Notoginseng(Burk.)F.H.Chen.
