目的评价信宜与海南产益智的质量。方法采用薄层色谱法对各批益智样品进行薄层色谱分析;采用水蒸气蒸馏法提取挥发油并对其含量进行方差分析;用气相色谱-质谱联用仪分析挥发油的化学成分并测定其成分的相对百分含量。结果信宜与海南产益智的薄层色谱行为基本一致;3批信宜产益智挥发油的平均含量为1.55%,3批海南产益智挥发油的平均含量为1.54%;从两产地益智挥发油中共鉴定出68个成分,两产地益智含量最高的成分均为(+)-朱栾倍半萜。结论信宜产益智与海南产者质量相近,初步认为信宜产益智可作为常用药材应用于临床。
Objective To evaluate the quality of Xinyi and Hainan Yizhi. Methods Thin-layer chromatography (HPLC) was used to analyze thin-layer chromatography (HPLC) of volatile oil from different batches of samples. Volatile oil was extracted by steam distillation and analyzed by ANOVA. The chemical constituents of volatile oil were analyzed by gas chromatography-mass spectrometry Relative percentage. Results Xinyi was consistent with the TLC of Hainan Yizhi. The average content of the three batches of Xinyi Yizhi Zhi volatile oil was 1.55%. The average content of three batches of Hainan Yizhi Zhi volatile oil was 1.54% A total of 68 components were identified in the volatile oil. The highest content of the two products was (+) - valencene. Conclusion Xinyi Chanzhi is similar in quality to that of Hainan farmer. It is believed that Xinyi Chanzhi can be used as clinical medicine in clinic.
