| 中文摘要: |
| 采用同时蒸馏萃取-气相色谱质谱联用（SDE-GC-MS）的方法分析了蝉拟青霉、拟细羽束梗孢、根足被毛孢菌丝的挥发性成分，从中分别鉴定出44、28和19种化合物，它们主要为萜类化合物、芳香族化合物、醇类、烷烃类、酯类和醛类。成分比较发现，3种虫生真菌挥发性物质中有3种主要共有成分，分别为丁羟基甲苯、1-辛烯-3-醇、苯乙醛。除共有成分外，它们各自都有大量特有成分，其中蝉拟青霉主要有5-甲基-2-呋喃-乙酸酯、反式-2,4-癸二烯醛、长叶烯等；拟细羽束梗孢主要有5-羟基-2-癸烯酸-δ-内酯、2,4-二甲基-恶唑、苯酚、β-榄香烯等；根足被毛孢主要有3,4,5-三甲基-苯甲醛、1,3-二甲基-3,4,5,6-四氢化-2(1H)嘧啶、顺式-2-羟基-1-（羟甲基）-9-十八碳一烯酸乙酯。 |
| 英文摘要: |
| Volatile components of Paecilomyces cicadae, Isaria gracilioides and Hirsutella heteropoda were extracted by method of simultaneous distillation extraction (SDE), and analyzed with gas chromatography-mass spectrometry (GC-MS). There were 44, 28 and 19 compounds were identified from the three species respectively. The main components were terpenoids, aromatic compounds, alcohols, alkanes, esters and aldehydes. Components’ comparison revealed that butylated hydroxytoluene, 1-octen-3-ol, benzeneacetaldehyde and decamethyl-cyclopentasiloxane existed commonly in all the 3 species. Besides the 3 main common components Paecilomyces cicadae contained uniquely 5-methylfurfuryl acetate, (E,E)-2,4-decadienal and decahydro-4,8,8-trimethyl-9-methylene-1,4-methanoazulene; Isaria gracilioides contained uniquely 5,6-dihydro-6-pentyl-2H-pyran-2-one, 2,4-dimethyl-oxazole, phenol and 1-ethenyl-1- methyl-2,4-bis(1-methylethenyl)-cyclohexane, and Hirsutella heteropoda contained uniquely 3,4,5-trimethoxy-Silane, (4-methoxyphenoxy)trimethyl-benzaldehyde, 1,3-dimethyl-3,4,5,6-tetrahydro-2(1H)-pyrimidinone, and 9-octadecenoic acid(Z)-2-hydroxy-1-(hydroxymethyl)ethyl ester. |
