摘要
目的 分析比较鬼针草属五种植物的挥发油成分.方法 采用水蒸气蒸馏法提取鬼针草属植物的挥发油,用气相色谱-质谱(GC-MS)联用技术分析山东鬼针草属的5种植物挥发油成分,并用色谱峰面积归一化法确定挥发油成分的百分含量.结果 金盏银盘、婆婆针、狼杷草、小花鬼针草、鬼针草(商品药材)的挥发油含量分别为0.160％,0.083％,0.023％,0.090％,0.093％.确认的化合物数目分别为20,45,10,61,9,占挥发油总量的比例分别是100％、93.11％、100％、89.37％、99.59％.结论 5个种的挥发油成分及含量差异较大.
Abstract
Objective To analyze the constituents of volatile oils from five Bidens L. Species in Shandong province. Methods The essential oils were extracted from five Bidens L. Species by steam distillation and the chemical compositions were further identified by GC-MS. The relative contents of essential oils were determined by area normalization method. Results The contents of volatile oils were 0.160%, 0.083%, 0.023%, 0.090%, 0.093%, respectively, for Bidens biternata (Lour.) Merr.et Sherff, Bidens pilosa Linn., Bidens tripartite (Lour.) Merr.et Sherff, Bidens parviflora Willd., Bidens bipinnata L.(commercial medicinal materials). Accordingly, the numbers of determined volatile compounds were 20, 45, 10, 61, 9, respectively, responsible for 100%, 93.11%, 100%, 89.37% and 99.59% of the total amount of volatile oils from different Bidens L. Species. Conclusion There are significant differences in the constituents and contents of volatile oils from five Bidens L. Species.
