摘 要: 本文采用水蒸气蒸馏法提取抗褐飞虱品种药用野生稻(Oryza officinalis)和感褐飞虱品种栽培稻(O.sativa)的挥发油,并运用气相色谱-质谱法(GC/MS)对二者的化学成分进行种类和含量的比较分析。结果表明,两种植物材料的挥发油在种类和含量上存在明显差异,如,糠醛(药用野生稻7.60%栽培稻0%;2,3-苯并二氢呋喃(药用野生稻10.80%,栽培稻3.32%);4-乙烯基-2-甲氧苯酚(药用野生稻22.99%,栽培稻7.32%)。推测含量较高的糠醛、2,3-苯并二氢呋喃和4-乙烯基-2-甲氧苯酚可能是药用野生稻对褐飞虱的活性成份。 The essential oils from O. offtcinalis and O. sativa were extracted by steam distillation and the chemical composition and content of the essential oils were analyzed by gas chromatography-mass spectrometry(GC/MS). The results show that the chemical composition and content of the essential oils in the two plants were different,for example,furfural ( O. officinalis 7.60%, O. sativa 0% ) ;2,3-dihydrobenzofuran( O. officinalis 10.80%, O. sativa 3.32% ) ;4-vinyl-2-methoxy-phenol( 0. officinalis 22.99% ,0. sativa 7.32% ). So ,it is speculate that these compounds with higher level in O. officinalis, for example, furfura1,2,3-dihydrobenzofuran and 4-vinyl-2-methoxy-phenol, are possibly active components.
