Embodiment Construction

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0022] A method for identifying Gastrodia elata based on near-infrared spectroscopy, the method steps are as follows:

[0023] (1) Collect Gastrodia elata samples: select 82 representative fresh Gastrodia elata samples from different origins; they are identified as different varieties of Gastrodia elata; wash with tap water, rinse with deionized water, cut into thin slices, steam through the heart, 60 ℃ Oven dry. Pass through a 60-mesh sieve after grinding, seal and store for later use;

Abstract

The invention relates to a radix gastrodiae elatae identification method based on near-infrared spectroscopy and stoichiometry, and radix gastrodiae elatae samples of different origins and different varieties are studied. The radix gastrodiae elatae identification method comprises the following steps: selecting three sensitive bands for identifying radix gastrodiae elatae, namely 4,007.02 cm<-1> to 7,254.89 cm<-1>, 4,080.84 cm<-1> to 7,046.62 cm<-1>, and 7,594.57 cm<-1> to 8,651.10 cm<-1>, and establishing an identification model with a partial least squares method-discriminant analysis methodand a TQ Analyst 9 discriminant analysis method; selecting a standard sample set of radix gastrodiae elatae from the samples, correcting and verifying the sample set, and identifying the variation ofradix gastrodiae elatae samples by Markov distance calculation. The radix gastrodiae elatae identification method has the advantages of high efficiency and zero destruction, rapid detection and highaccuracy, and can be used for identification of radix gastrodiae elatae.

Description

technical field [0001] The invention relates to the field of near-infrared spectroscopy identification, in particular to an identification method for Gastrodia elata based on near-infrared spectroscopy. Background technique [0002] Gastrodia [ Gastrodia elata Bl], also known as Chijian, is the dry tuber of Orchidaceae. It has been a good medicine for curing diseases and strengthening the body since ancient times. It is called "the king of medicinal materials" and is also a green health care treasure. There are "three towns", "three antisenses" and "one tonic", that is, antiepileptic, anticonvulsant, antirheumatic, sedative, antispasmodic, analgesic, and tonic. Modern pharmacological research shows that Gastrodia elata has four major therapeutic effects: protective effect on the nervous system; cardiotonic effect on the cardiovascular system; hypoxia tolerance and immune function enhancement. Research in recent years has found that Gastrodia elata also has the functions o...
