目的:对宜昌产鲜鱼腥草的挥发油成分进行特征图谱研究,为评价该地区鱼腥草资源的质量提供简便、快捷的方法。方法:采用水蒸气蒸馏法提取不同生长时期的鲜鱼腥草挥发油,并通过气相色谱进行分析,经软件拟合得到标准图谱。结果:对10批鲜鱼腥草进行分析,建立鲜鱼腥草挥发油气相色谱特征图谱。结论:该方法重复性好,所建立的气相色谱特征图谱可用于鲜鱼腥草的质量控制。
OBJECTIVE: To study the characteristic maps of the volatile oil constituents of fresh Houttuynia cordata from Yichang and provide a simple and rapid method for evaluating the quality of Houttuynia cordata resources in this area. Methods: The volatile oil of Houttuynia cordata Houttuyniae at different growth stages was extracted by steam distillation and analyzed by gas chromatography. The standard maps were obtained by software fitting. Results: 10 batches of fresh Houttuynia cordata were analyzed to establish gas chromatography chromatogram of volatile oil of Houttuynia cordata. Conclusion: This method has good reproducibility and the established gas chromatographic feature map can be used for quality control of Houttuynia cordata.
