Abstract

The invention discloses a method for rapidly identifying the trueness and quality of radix notoginseng. The method is characterized by detecting a sample by adopting an electronic nose and an electronic tongue and analyzing and identifying the sample by adopting PCA (principal component analysis) and DFA (dynamic financial analysis) methods, thus distinguishing the trueness and quality of radix notoginseng. The method has the advantages of high recognition rate and high identification speed.

Description

technical field [0001] The invention relates to the field of decoction pieces of traditional Chinese medicine, in particular to a method for quickly identifying the authenticity of Panax notoginseng. Background technique [0002] Panax notoginseng is the dry root and rhizome of Panax notoginseng (Burk.) F.H.Chen. Because of its effect of dispelling blood stasis and hemostasis, reducing swelling and relieving pain, it can be used for hemoptysis, vomiting blood, epistaxis, hematochezia, metrorrhagia, traumatic bleeding, chest and abdomen tingling pain, tumbling swelling pain, and is an important Chinese medicine variety. [0003] However, there is a phenomenon of mixed counterfeit products on the market. On the one hand, Panax notoginseng and its counterfeit products have a high similarity in appearance, and most of them are used as powder, which is mainly light yellow or yellow-white, which makes it difficult to effectively distinguish them. On the other hand, due to climat...
