摘　　要：用水蒸气蒸馏法提取降香挥发油,经GC-MS分析鉴定出16个化合物,占挥发油总量的98.04%,其主要成分有氧化石竹烯(54.22%)、7,11-二甲基-10-十二碳烯-1-醇(14.11%)、6,11-二甲基-2,6,10-十二碳三烯-1-醇(10.24%)和橙花叔醇(10.22%)等。同时,测定了挥发油的体外抗菌活性,结果表明,降香挥发油对金黄色葡萄球菌(Staphylococcus aureus)和耐甲氧西林金黄色葡萄球菌(Methicillin-resistant Staphylococcus aureus,MRSA)均具有抑制作用。The volatile oil from the heartwood of Dalbergiae odoriferae T.Chen was extracted by hydrodistillation in a Clevenger-type apparatus,and analyzed by gas chromatography-mass spectrometry(GC-MS).A total of sixteen compounds,constituting over 98.04% of the total oil,were identified from the volatile oil.The major components of volatile oil were caryophyllene oxide(54.22%),7,11-dimethyl-10-dodecen-1-ol(14.11%),6,11-dimethyl-2,6,10-dodecatrien-1-ol(10.24%) and nerolidol(10.22%).In addition,antibacterial activity of the volatile oil was evaluated.The oil showed activity against S.aureus and MRSA.
