扁桃叶挥发油化学成分的研究

Study on the chemical constituent of volatile oil from the leaves of Mangifera persiciformis

采用水蒸气蒸馏法提取,运用气相色谱-质谱联用技术(GC-MS),首次对扁桃叶挥发油的化学成分进行分析,并用气相色谱面积归一化法测定各成分的相对百分含量。共鉴定出其中的38种化合物,占挥发油总量的94.52%,其主要成分为:大根香叶烯(18.33%),喇叭醇(9.46%),石竹烯(9.04%),δ-杜松烯(5.73%),1Rα--蒎烯(5.32%),β-榄香烯(4.90%),α-古芸烯(4.26%),5-甲基-2-(1,1二-甲基乙基)-苯酚(3.78%),别芳萜烯(3.45%),δ-榄香烯(3.41%),γ-芹子烯(3.27%),斯巴醇(3.20%),其中多种成分具有生物活性。本结果为综合开发利用扁桃叶提供理论依据。

Volatile oil,extracted from the leaves of Mangifera persiciformis by steam distillation,was analyzed by gas chromatography-mass spectrometry（GC-MS）for the first time.The relative contents in the volatile oil were determined by peak area normalization.38 components were identified,which accounted for 94.52% of the volatile oil of the leaves.The major compositions were Germacrene D（18.33%）,Ledol（9.46%）,Caryophyllene（9.04%）,δ-Cadinene（5.73%）,1（R）-α-Pinene（5.32%）,β-Elemene（4.90%）,α-Gurjunene（4.26%）,Phenol,2-（1,1-dimethylethyl）-5-methyl-（3.78%）,allo-aromadendrene（3.45%）,δ-Elemene（3.41%）,Selina-3,7（11）-diene（3.27%）,Spathulenol（3.20%）,and many of the components had biological activity.This study will provide theoretic basis for the multiple utilization and developments of the leaves of M.persiciformis.
