采用水蒸气蒸馏法提取秀丽海桐(Pittosporum pulchrum Gagnep.)叶中的挥发油,应用GC-MS联用技术进行挥发油成分分析.结果从秀丽海桐叶挥发油中分离出51个组分,确认出其中的37种成分,其主要成分为a-蒎烯(29.27% ),β-蒎烯(17.84%)、坎烯(3.90%)和桃金娘烯醇(3.60%).确认的37种成分为首次从该植物中鉴定出来.%The volatile oil from the leaves of P. pulchrum was extracted by hydrodistillation method and the constituents were analysed with capillary gas chromatography and GC-MS-DS.51 compounds were obtained and 37 of them were identified. α-Pinene(29.27%), β-Pinene (17.84%), Camphene(3.90%) and Myrtenol(3.60%) were the major chemical constituents of volatile oil from the leaves of P. pulchrum . Among the 51 compounds, 37 of them were first identified from this plant.
