金银花挥发油GC指纹图谱研究

Study of GC fingerprint of essential oils from flower of Lonicera japonica

目的:建立10批金银花药材挥发油的指纹图谱。方法:用水蒸气蒸馏法提取,GC法分析对比10批金银花药材挥发油的成分。结果:10批金银花药材的挥发油相似度较高。结论:该指纹图谱方法简便,重现性好,可作为金银花药材的质量控制方法之一。

Objective： To study and establish the GC fingerprint of essential oils of 10 batches the flower of Lonicera japonica. Method： The essential oils were extracted by steam distillation from ten batches of the flowers, then separated by capillary gas chromatography. Result： The similarity of 10 batches of the flower of L. japonica was high. Conclusion： The method was reliable, and can be used to evaluate the quality of the flower of L. japonica.
