西藏林芝蜂蜜与其他地区蜂蜜挥发性成分比较分析
Comparative Analysis of Volatile Components Between Nyingchi Honey from Xizang and Honey from Other Regions
摘要
Abstract
[Objective]To explore the characteristic volatile components of honey from Nyingchi,Xizang.[Method]HS-SPME combined with GC-MS was used to analyze the volatile components of honey from Nyingchi of Xizang,Qinling of Shaanxi,Shannan of Xizang,Paektu of Jilin and Shangri La of Yunnan.In addition,the difference of volatile components between Xizang Nyingchi honey and honey from other four produ-cing areas was studied with Chemometrics.[Result]103 ingredients were identified in honey from five regions,including 61 species of Nyingchi honey in Xizang,36 species of Qinling honey in Shaanxi,49 species of Shannan honey in Xizang,31 species of Paektu Mountain honey in Jilin,and 42 species of Shangri La honey in Yunnan.The most abundant types of volatile components in Nyingchi honey were mainly esters,which ac-counted for a relatively large proportion,while alcohols and aldehydes accounted for a relatively large proportion in the other four regions.Analy-sis of variance found that there were significant differences in the content of 45 compounds among different habitats.Orthogonal partial least squares discriminant analysis further identified ethyl salicylate,n-hexanoic acid,octane,phenylpropanoic acid ethyl ester,ethyl pentanoate,ethyl octanoate eight compounds of phenethyl alcohol and octanal were key substances to distinguish Nyingchi honey from honey from other regions.Among them,ethyl phenylpropanoic acid,ethyl pentanoate and ethyl octanoate were only detected in Nyingchi honey.[Conclusion]Esters are of great significance in distinguishing Nyingchi honey from honey from other regions.关键词
