木蝴蝶果实不同组织挥发性化学成分研究

Volatile Chemical Constituents in Different Tissues of Fruits of Oroxylum indicum(L.)Kurz

为探究木蝴蝶果实不同组织的挥发性成分,本研究利用气相色谱仪测定了木蝴蝶果实中种子、果皮及翅3种组织中的挥发油成分。结果表明:木蝴蝶种子挥发油中主要成分有7种,包括丁基羟基甲苯、丁基-3-庚烷基-邻苯二甲酸酯、苯乙酮、苯基乙醇、4-甲氧基苯乙酮、4′-羟基苯乙酮和6-Octadecenoic acid,其中丁基羟基甲苯相对含量最高为49.77%;木蝴蝶的果皮挥发油中主要成分有3种,即丁基羟基甲苯、丁基-3-庚烷基-邻苯二甲酸酯以及柠檬酸丁酯,其中丁基羟基甲苯相对含量最高,为57.6%;在木蝴蝶的翅挥发油中主要成分有丁基羟基甲苯和丁基-3-庚烷基-邻苯二甲酸酯,其中丁基羟基甲苯相对含量最高为65.66%。在木蝴蝶果实各个组织中共测出8种主要的化合物,其中丁基羟基甲苯和丁基-3-庚烷基-邻苯二甲酸酯在种子、果皮及翅中均有发现。

In order to explore the volatile components in different tissues of the Oroxylum indicum(L.)Kurz fruit,this study determined volatile oil components in seeds,pericarp and wing of the fruit by gas chromatograph.The results showed that,there were seven main compounds in the volatile oil of Oroxylum indicum(L.)Kurz seeds,such as butyl hydroxy toluene,phthalate butyl hept-3-yl,acetophenone,phenyl ethanol,4-methoxyacetophenone,4-hydroxy-acetophenone 6-octadecenoic acid among which the relative content of butyl hydroxy-toluene was the highest,49.77%.There were three main compounds in the volatile oil of Oroxylum indicum(L.)Kurz pericarp,including butyl hydroxy toluene,phthalate butyl hept-3-yl and butyl citrate,the highest content of butyl hydroxy toluene was 57.6%;In the volatile oil of the wings of Oroxylum indicum(L.)Kurz,the main components were butyl hydroxy toluene and phthalate,butyl hept-3-yl,among which the relative content of butyl hydroxy toluene wss the highest of 65.66%;A total of 8 major compounds were detected in various tissues of the fruit,including butyl hydroxy toluene and phthalate,butyl-hept-3-yl were found in seeds,pericarp and wings.
