摘要
[目的]分析比较不同品种或产地木犀科小叶苦丁茶老叶及芽中挥发油成分的异同。[方法]采用水蒸气蒸馏法分别对不同品种或产地的小叶苦丁茶中的挥发油进行提取,利用气质联用技术分析所提取的挥发油成分。[结果]共鉴定55个化合物,7个不同批次小叶苦丁茶老叶及芽中的成分具有较大的相似性,相对含量最高的均为以芳樟醇(48.34%～79.25%)为主的单萜类成分,其他含量较高的成分有α-松油醇、香叶醇何橙花醇等。[结论]该方法为小叶苦丁茶的质量控制和资源合理开发利用提供了科学依据。
[Objective] To compare the chemical components of volatile oil from small leaves Ku-Ding-Cha which belonged to the family Oleaceae.[Method] Volatile oils of small leaves Ku-Ding-Cha in different production areas were extracted by the technique of steam distillation;then,the components of volatile oils were analyzed by gas chromatography mass spectrometry（GC-MS）.[Result] A total of 55 compounds were identified.There was great similarity in the old leaves and buds of Ku-Ding-Cha in different batches.Linalool had the highest content（48.34%-79.25%）;α-terpineol,geraniol and nerol had relatively high content.[Conclusion] This research provided scientific references for the quality control and reasonable utilization of the small leaves Ku-Ding-Cha.
