摘要
利用气相色谱-质谱(GC/MS)联用技术分析荆条叶挥发油中的化学组成。结果表明:荆条叶挥发油中共分离出了36种组分,确定了29种成分的化学结构和相对含量,占总组分相对含量的94.68％。其中萜类及其衍生物22种,占89.13％。含量最高的成分是β-丁香烯(48.70％),其次是β-金合欢烯(15.52％)等。
The volatile oil extracted from dried leaves of Vitex negundo var. heterophylla Rehd. was determinated by gas chromatography-mass spectrometry (GC/MS). Thre results showed thirty-six constituents in sample have been separated. Among which, the chemical structure and relative content of twenty-nine constituents were identified, the sum of their contents was 94. 68% of the total. The twenty-two constituents assigned to ter-penoids and their derivatives make up 89. 13% of the total volatile substances. The main component was β-Caryophyllene making up 48. 70% of the total, β-Farnesene making up 15.52%.
