蒜香藤的挥发性成分分析(英文)

Essential Oil Composition of A Novel Garlic Vine Pseudocalymma alliaceum

采用采用气相色谱-质谱联用技术对蒜香藤不同部位叶、茎与果的挥发性成份进行分析。结果发现,叶、茎、果中可定性定量的化合物分别占挥发性成份总量的97.6%、95.4%与97.4%。在不同部位中,主要的化合物是含硫化合物,分别占挥发性总量的78.4%、54.0%与81.0%。叶、茎、根中主要的挥发性成份有二烯丙基二硫化物(48.9%、25.4%、34.2%)和二烯丙基三硫化物(18.4%、14.0%、29.8%)。蒜香藤的挥发性化学成份与大蒜的相似,尤其体现在含硫化合物上,因此,蒜香藤可以作为大蒜的潜在替代物,其药理活性需要进一步开发研究。

In this study, the leaf, stem, and fruit of Pseudocalymma alliaceum were distilled and the essential oil composi- tion was studied by GC-MS. The identified components constituted 97.6% ,95.4% and 97.4% of the leaf, stem,and fruit oils, respectively. The major components of different parts of P. alliaceum were sulfur-containing compounds, amoun- ting to 78.4% ,54.0% and 81.0% of essential oil composition in leaves, stems, and fruits, respectively. The result showed that the main constituents of the essential oil of leaves, stems, and fruits oils were diallyl disulphide （48.9% ,25. 4% and 34.2% ） and diaUyl trisulfide（ 18.4% ,14.0% and 29.8% ）. It was concluded that the essential oil composi- tion of P. alliaceum was similar with the garlic Allium sativum, especially to sulfur-containing compounds. The garlic vine P. aUiaceum is a potential substitute of A. sativum and its pharmaceutical effects need to be studied in the future.
