摘要： 目的 从气味和化学成分2个方面对鲜、干两类鱼腥草样本进行比较研究。方法 采用电子鼻技术和气相色谱质谱联用技术分别对鲜、干两类鱼腥草样本的“腥味”和挥发性成分进行分析,采用雷达图、主成分分析（PCA）、正交偏最小二乘判别分析 (OPLS-DA)等数据建模及可视化分析方法,对鲜、干两类鱼腥草样本进行比较,在此基础上采用相关性分析揭示化学成分表达与“腥味”指标间的相关性。结果 电子鼻10种传感器检测指标的雷达图直观表达了鲜、干鱼腥草的“腥味”特征差异,通过建模分析（PCA、OPLS-DA）整体表征了鲜、干鱼腥草组间的气味差异并对两者进行了区分,筛选确定了W1W、W2W、W3C、W5C 4种主要差异传感器指标;GC-MS分析从鲜、干鱼腥草中共鉴定表征了90个挥发性成分,建模分析（PCA、OPLS-DA）整体表征了鲜、干鱼腥草组间的化学成分差异并对两者进行了区分,筛选得到35个主要差异成分;相关性分析结果表明d-柠檬烯、(±)-2-蒎烯、Beta-蒎烯、石竹素、（-）- spathulenol、正壬醛、（Z）-β-法呢烯、月桂烯、邻-异丙基苯为代表的9种物质,在鱼腥草“腥味”中起到重要影响。结论 以上研究结果揭示了鲜、干两类鱼腥草的“腥气”特征及差异,为建立基于感官评价技术的鱼腥草质量评价体系以及鲜、干鱼腥草的质量控制提供参考。

Abstract: Objective To conduct a comparative study of the odor and chemical composition of fresh and dried houttuynia samples. Methods The “fishy odor” and volatile components of fresh and dried houttuynia samples were analyzed using the electronic nose technique and gas chromatography-mass spectrometry (GC-MS). The correlation between the expressions of chemical components and the “fishy odor” indexes was analyzed based on a comparison of fresh and dried houttuynia samples. Results The radar map of 10 sensors of the electronic nose visually depicted the differences in the “fishy odor” between fresh and dried houttuynia. The differences in odor between fresh and dried houttuynia groups were characterized by modeling analysis (PCA, OPLS-DA). Four main differential sensor indicators-W1W, W2W, W3C, W5C-were screened. GC-MS analysis identified and characterized a total of 90 volatile components from fresh and dried houttuynia, while modeling analysis (PCA, OPLS-DA) characterized the differences in chemical composition between fresh and dried houttuynia groups before 35 major components were screened. The results of correlation analysis showed that nine substances, including d-pinene, (±)-2-pinene, beta-pinene, stigmasterol, (-)-spathulenol, n-nonenal, (Z)-beta-farnesene, lauricene and o-isopropylbenzene, played an important role in the “ fishy odor “ of houttuynia. Conclusion The above findings reveal the characteristics of and differences in the “fishy odor” of fresh and dried houttuynia, and provide reference for the establishment of a quality evaluation system based on sensory evaluation techniques and quality control of fresh and dried houttuynia.
