蝼蛄的近红外光谱鉴别研究

Studies on identification of Gryllotalpa by near-infrared diffuse reflectance spectrometry

目的 :对蝼蛄的不同种和异地的同一种以及混乱品种进行鉴定、分析。方法 :应用傅立叶变换近红外光谱仪。结果 :聚类分析表明不同的蝼蛄种间聚类关系较远 ;虽异地但为同一种的蝼蛄聚类关系较近 ;相近地理位置所产蝼蛄 ,其聚类关系较近 ;混乱品种蟋蟀和东方蝼蛄的聚类关系较近。结论 :近红外分析法可应用于蝼蛄种的分类以及蝼蛄药材的分析、鉴定。

Objective: To identify and analyse the different species, same species in different regions and confusion species. Method:Near-infrared diffuse reflectance spectrometry was used. Result: Clustering analysis showed that clustering relations were far among different Gryllotalpa species and close among the same species from different regions,and there were close relations among the same species from near regions and between Teleogryllus emmus and G. orientalis. Conclusion: Near-infrared diffuse reflectance spectrometry method can be used in classification and identification of Gryllotalpa. [
