摘要: 以校园植物白玉兰(Magnolia denudata)的花瓣为材料,用水蒸气索氏提取法提取自然阴干、40、50、60 ℃ 4种干燥条件下白玉兰花瓣的挥发油,计算挥发油的出油率,用GC-MS获得其挥发油各成分的总离子流图谱,结合计算机检索技术对化合物进行结构鉴定, 并用色谱峰面积归一化法计算各成分的相对质量分数。结果表明,在自然阴干、40、50、60 ℃条件处理下,分别鉴定出62、53、48和46种化合物,分离的化合物分别占挥发油类成分总量的92.21%、89.29%、89.48%和87.59%。4种不同干燥处理样品的挥发油共有成分有46种,挥发油的主要成分为倍半萜类化合物、萜烯类化合物和萜醇类化合物。石竹烯为挥发油含量最高的成分,其次为芳樟醇、(E,E)-1-甲基-5-亚甲基-8-异丙基-1,6-环癸二烯、乙酸松油酯、α-松油醇、4-萜烯醇和桉叶油素。

Abstract: Campus plant Magnolia denudata petals as experimental materials, the extraction of volatile oil of Magnolia petals shade, 40 ℃, 50 ℃ and 60 ℃ with steam distillation of 4 kinds of drying conditions, calculated by the volatile oil yield, the volatile oil components of the total ion flow map with GC-MS. The combination of computer retrieval technology for structural identification of compounds, the relative mass fraction of each component was calculated by area normalization method. In the treatment of natural shade, 40 ℃ 50 ℃ and 60 ℃, respectively identified 62, 53, 48 and 46 compounds, isolated compounds accounted for the total volatile oil components 92.21%, 89.29%, 89.48% and 87.59%. The volatile oil of four different drying samples contains 46 kinds. The main components of volatile oil are sesquiterpenes, terpenes and terpene alcohols. Caryophyllene for magnolia oil components in the highest content of volatile 4 kinds of samples, followed by linalool,(E,E)-1-methyl-5-methylene-8-isopropyl-1, 6-ring decadiene, Terpinyl Acetate, α-terpineol, 4-terpenols and cineole. The components of volatile oil were different under different drying conditions.

Key words: Magnolia denudata petals, GC-MS analysis, volatile oil
