本文利用GC-MS对小黄花茶（Camellia luteoflora Y.K.Li）的挥发性成分进行检测，分析和比较不同提取方法、不同器官间挥发性成分的异同。采用超声辅助提取法(Ultrasonic-Assisted Extraction，UAE)和顶空固相微萃取提取法(Head Space Solid-Phase Micro-Extractions, HS-SPME)分别提取小黄花茶花和叶的挥发油，利用气相色谱-质谱联用法（GC-MS）对其成分进行分析，用NIST08.LIB标准质谱检索库定性，并用峰面积归一法进行定量分析。结果显示花和叶中共检测到137种挥发性成分，鉴定出121种。花中共鉴定到74种化合物，其中含有15种萜类化合物，1种甾类化合物，11种芳香族化合物，及46种脂肪族化合物，含量最高的为芳樟醇（16.71%）；叶中共鉴定到72种化合物，含有23种萜类化合物，2种甾类化合物，14种芳香族化合物，及33种脂肪族化合物，含量最高的是反式-2-己烯醛（20.63%）；花和叶中共有芳樟醇、反式-2-己烯醛和己醛等25种化合物，分别占花挥发油含量的44.82%，叶的47.69%。本文从小黄花茶中鉴定到多种具有药理活性和吸引虫害的挥发性成分，为了解小黄花茶挥发性成分奠定了基础，为虫害防治及开发利用提供了理论依据。

The volatile components of Camellia luteoflora Y.K.Li were detected by GC-MS. The differences in volatile composition of Camellia luteoflora Y.K.Li from organs by different extraction methods were compared. The essential oil of C. luteoflora was extracted by ultrasonic-assisted extraction (UAE) and head space solid-phase micro-extractions (HS-SPME), respectively. Their components were analyzed by gas chromatography-mass spectrometry (GC-MS), and further identified by NIST08.LIB standard mass spectrometry library. The peak area normalization method was used to quantitatively analyze these compounds. A total of 137 volatile components were detected in flowers and leaves, and 121 were identified. The 74 compounds were identified in flowers, including 15 terpenoids, 1 steroids, 11 aromatic compounds and 46 aliphatic compounds. The content of linalool (16.71%) was the highest. The 72 compounds were identified in leaves, including 23 terpenoids, 2 steroids, 14 aromatic compounds and 33 aliphatic compounds. Trans-2-hexenal (20.63%) had the highest content. There were 25 compounds both in flowers and leaves, including linalool, trans-2-hexenal and hexanal, which accounted for 44.82% of flowers and 47.69% of leaves, respectively. In this work, a variety of volatile components with pharmacological activities and attracting insect pests were identified in C. luteoflora, which laid a foundation for understanding the volatile components of C. luteoflora and provided a theoretical basis for pests control and relative product development and utilization.
