摘要
为了利用厚朴树叶中所含的天然香料及药用成分,厚朴树叶经过加工可将其用做方便卫生的食品包装材料。对秦巴山区春秋两季的厚朴树叶中的挥发性物质采用水蒸气蒸馏法提取,利用气相色谱-质谱联用技术对挥发性物质进行分离和结构鉴定,运用气相色谱面积归一化法确定各组分的相对含量,分离出41种组分,鉴定出40种化合物。秦巴山区春秋两季厚朴树叶中的挥发性物质存在差异,其主要组分含量秋季较春季也有较大变化。体外抗氧化实验表明,春秋两季厚朴树叶挥发性物质对·OH均有明显的清除作用,秋季厚朴树叶挥发性物质对·OH的清除作用更为显著。
To empolder natural perfume and medicinal composition of the leaf of Magnolia officinalis obtained from Qinba Mountain,the leaf of Magnolia officinalis can be used as a convenient and sanitary food packing material after processing.These volatile components from Spring and Autumn leaves of Magnolia officinalis was extracted by steam distillation,respectively,the components of their volatile components were separated and structurally identified by gas chromatography/mass spectrometry,the relative contents of these components by the peak-area normalization method adopted in gas chromatography,41 components were separated and 40 components were identified,these major components and their relative contents of these major components were different.These volatile components of Spring and Autumn leaves of Magnolia officinalis were investigated by anti-oxidation activities,and they had obvious action to anti-oxidation activities of scavenging effect for ·OH especially Autumn leaves were better than Spring leaves.
