运用SPME与GC/MS联用技术从新鲜枫杨叶挥发性物质中共检测出化合物52种,主要成分是橙花叔醇(15.54%)、吉马烯A(14.22%)、反式子丁香烯(10.19%)、7,8,9,10-四氢化-S-三氮唑(3,4-A)-呔嗪(8.59%)、十六酸(6.22%);萎蔫枫杨叶挥发性物质中共检测出化合物32种,主要成分是α-红没药烯(17.69%)、橙花叔醇(16.64%)、反式子丁香烯(14.26%)、α-桉叶烯(9.14%);干枯枫杨叶挥发性物质中共检测出化合物31种,主要成分是反式子丁香烯(23.30%)、α-红没药烯(17.75%)、α-桉叶烯(12.69%)、橙花叔醇(8.35%)、杜松烯(7.0%)。随着枫杨萎蔫程度的变化,三者含有的化合物组分以及其相对含量都发生变化。本研究是首次报道枫杨的挥发性化学成分分析。
A total of 52 compounds were detected from the volatile compounds of Pterocarya stenoptera using SPME combined with GC/MS. The main components were nerolidol (15.54%), gemenen A (14.22%), and trans-fructose. (10.19%), 7,8,9,10-tetrahydro-S-triazole (3,4-A)-pyridazine (8.59%), hexadecanoic acid (6.22%); Thirty-two kinds of compounds were detected in the substance, and the main components were α-bispermene (17.69%), nerolidol (16.64%), trans-eugenoisene (14.26%), and α-limonene (9.14%). The total volatile compounds detected in the dried leaves of Pterocarya stenoptera were 31 compounds, and the main components were trans-eugenoisene (23.30%), α-bispermene (17.75%), α-limonene (12.69%), and orange. Huafu alcohol (8.35%), juniperene (7.0%). With the change of the wilting level of Pterocarya stenoptera, the composition of the three compounds and their relative contents all changed. This study is the first report of the volatile chemical composition of Pterocarya stenoptera.
