Abstract: 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.
