摘要: 为更好地实现天麻药食两用,使用顶空微萃取-气质联用(HS-SPME-GC-MS)方法检测鲜天麻的特殊“马尿味”气味成分,使用香气活力值评价各成分对于总体气味的贡献。分析结果显示,在4个处理组天麻中共分离鉴定得到27种挥发性化合物,包含烯、苯、酮、醛、醇、酚、有机酸7类化合物,其中22种成分报道有气味描述,表明天麻的特殊气味是由多种成分共同形成的复合型气味。天麻不同部位的共有成分分析、相对香气活力值分析及主成分分析结果显示8种成分为天麻气味成分的部分物质基础,其中正辛醛、月桂烯是天麻气味形成的主要成分。

Abstract:

In order to better realize the dual use of Gastrodia elata Bl. as medicine and food,the special "horse urine taste" odor components of fresh G. elata were detected by headspace solid-phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS),and the contribution of the detected components to the overall odor was evaluated by the odor activity value.The results showed that 27 volatile compounds were detected and identified in the four treatment groups,including seven compounds including olefin,benzene,ketones,aldehydes,alcohols,phenols and organic acids,and 22 of them had corresponding odor descriptions,indicating that the special odor of G. elata was a compound odor formed by multiple components.Analysis of common components in different parts of G. elata ,analysis of relative odor activity value and principal component analysis showed that eight components were part of the material basis of the odor components of G. elata,among which n-octyl aldehyde and laurene were two of the main components in the odor formation of G. elata.

Key words: Gastrodia elata Bl., aroma components, HS-SPME, GC-MS, odor activity value
