| 中文摘要:目的：分析黑叶小驳骨的挥发性成分。方法：本实验以固体直接进样结合气相色谱质谱联用技术，通过色谱峰的质谱匹配度和保留指数相似度对色谱峰进行定性，用总离子流色谱峰的峰面积进行归一化定量。结果：共分离出29种组分，鉴定了其中22种，其相对含量占总检出物的94.46％。其中含量较高的组分有棕榈酸（39.20%）、角鲨烯（10.25%）、硬脂酸（10.05%）、油酸（7.86%）、植醇（5.21%）等。结论：黑叶小驳骨的挥发性成分主要由大量的饱和脂肪酸和不饱和脂肪酸组成。采用固体直接进样技术，能够简化实验步骤，在中药成分分析中具有潜在的开发价值。 |

| Abstract:Objective：To assay the volatile compounds of Justicia ventricosa.Methods：The volatile compounds in J.ventricosa were analyzed by GC-MS with Chromato Probe，and were identified by combining mass NIST spectrometry database with Kovats retention indices.Then the peak area normalization method was used to calculate the relative percentage of each ingredient.Results：The results showed that 29 volatile compounds were separated，and 22 compounds were identified，accounting for 94.46％ of the total volatile compounds.The compounds with high contents were as follows：n-hexadecanoic acid（39.20%），Squalene（10.25%），octadecanoic acid（10.05%），oleic acid（7.86%），phytol（5.21%），and so on.Conclusion：The major type of the volatile compounds in J.ventricosa were saturated fatty acid and unsaturated fatty acid.The experimental procedure is simplified by using Chromato Probe.The results indicate that the method has potential exploitation value in the analysis of traditional Chinese medicine. |
