摘要: 采用顶空固相微萃取(HS-SPME)与气相色谱-质谱联用(GC-MS)分析厚鳞柯(Lithocarpus pachylepis)不同部位(果壳、果仁、花、叶、枝)的化学成分组成、相对含量及差异。结果表明,厚鳞柯各部位挥发性成分及相对含量存在较大差异,5个部位共检测出110种化合物,共9类挥发性化合物,分别为醇类、酚类、醚类、醛类、酸类、酮类、烷烃类、烯烃类和酯类化合物;果壳、果仁、花、叶、枝中分别鉴定出41、38、42、38、39种成分。厚鳞柯的5个部位中鉴定出9种共有成分,分别是正壬醛、癸醛、正十四烷、正十六烷、正十七烷、咖啡因、植酮、邻苯二甲酸二异丁酯和邻苯二甲酸二丁酯;各部位中共有成分的相对含量由高到低依次为枝、果仁、果壳、花和叶。5个部位中均有独特的挥发性成分,其中果壳中有18种、果仁中有9种、花中有14种、叶中有17种、枝中有10种。对共有成分进行主成分分析,提取了3个主成分,累计方差贡献率为84.63%,其中咖啡因、正十六烷、癸醛、邻苯二甲酸二丁酯和正十七烷的贡献率较大,均与主成分呈高的正相关性,是影响厚鳞柯挥发油的关键性成分。

Abstract: The chemical composition, relative contents, and differences in different parts (shell, kernel, flower, leaf and branch) of Lithocarpus pachylepis were analyzed using headspace solid-phase microextraction (HS-SPME) combined with gas chromatography-mass spectrometry (GC-MS). The results showed significant differences in volatile components and relative contents among different parts of Lithocarpus pachylepis. A total of 110 compounds belonging to 9 categories (alcohols, phenols, ethers, aldehydes, acids, ketones, alkanes, alkenes and esters) were detected. The shell, kernel, flower, leaf, and branch contained 41, 38, 42, 38 and 39 compounds, respectively.Nine common components were identified across all five parts of Lithocarpus pachylepis, including n-nonanal, decanal, n-tetradecane, n-hexadecane, n-heptadecane, caffeine, phytone, diisobutyl phthalate, and dibutyl phthalate.The relative contents of common components in descending order were branch , kernel, shell, flower, and leaf. Unique volatile components were identified in each part, with 18 in the shell, 9 in the kernel, 14 in the flower, 17 in the leaf, and 10 in the branch. Principal component analysis of common components extracted three principal components (cumulative variance contribution rate 84.63%). Caffeine, n-hexadecane, decanal, dibutyl phthalate, and n-heptadecane showed high positive correlations with principal components and were identified as key contributors to the volatile oil of Lithocarpus pachylepis.

Key words: Lithocarpus pachylepis, volatile components, headspace solid-phase microextraction (HS-SPME), gas chromatography-mass spectrometry (GC-MS)
