摘要:

为探究羌活(Notopterygium incisum)1年实生苗“蚕环”结构形成过程中挥发性有机化合物(VOCs)的动态变化并识别其关键气味标志物,本研究采用电子鼻技术与顶空固相微萃取-气相色谱-质谱联用(HS-SPME-GC-MS)技术,对“蚕环”形成前后的羌活植株进行多维解析。电子鼻分析显示,羌活特征气味主要来源于根茎部位,对萜烯类敏感的W5S等传感器响应值在“蚕环”形成后显著增强,表明其特征气味主要伴随“蚕环”的形成而产生,萜烯类化合物为其关键物质基础。GC-MS分析进一步揭示,萜类化合物是构成特征气味的主要物质。结合相对气味活度值(ROAV)分析发现,“蚕环”形成后显著上调的2-丙烯酸乙酯和1,2-双(叔丁硫基)乙烷共同构成羌活刺激性气味,而桉叶醇、2-甲基丁醛等萜类、酯类及芳香类化合物则提供草本花香、木质香等香气以平衡整体气味轮廓。电子鼻响应与GC-MS数据强相关,验证了其在快速监测复杂VOCs动态变化的可靠性。本研究明确了羌活“蚕环”的形成是其特征性气味产生的关键节点,解析了其物质基础及关键气味标志物,为揭示羌活气味形成机制及品质评价提供了科学依据。

Abstract:

To investigate the dynamic changes in volatile organic compounds(VOCs) during the formation of ‘worm-like rings’ in annual Notopterygium incisum seedlings and identify key odor markers, this study employed an integrated analytical strategy. This approach combined electronic nose technology with headspace solid-phase microextraction coupled with gas chromatography-mass spectrometry(HS-SPME-GC-MS) to profile N. incisum plants multidimensionally before and after ‘worm-like rings’ formation. Electronic nose analysis revealed that the characteristic odor of N. incisum primarily originated from the rhizome. Response values of sensors sensitive to terpenes, such as W5S, increased significantly after the formation of ‘worm-like rings’, indicating that the characteristic odor is predominantly generated concomitantly with ‘worm-like rings’ development, with terpenes serving as a key material basis. GC-MS analysis further identified terpenoids as the main components constituting the characteristic odor. Combined with relative odor activity value(ROAV) analysis, significantly upregulated compounds after ‘worm-like rings’ formation were identified. Notably, ethyl 2-propenoic acid, ethyl ester and propane, 2,2'-[1,2-ethanediylbis(thio)]bis[2-methyl-, jointly contributed to the pungent odor. Meanwhile, terpenoids including eucalyptol and butanal, 2-methyl-, along with esters and aromatic compounds, provided herbal-floral and woody aromas that balanced the overall odor profile. The strong correlation between electronic nose responses and GC-MS data validated the reliability of electronic nose for rapidly monitoring complex VOC dynamics. This study clarifies that the formation of ‘worm-like rings’ in N. incisum represents a critical juncture for the emergence of its characteristic odor, elucidates its material basis and key odor markers, and provides a scientific foundation for understanding the odor formation mechanism and quality evaluation of N. incisum.
