OBJECTIVE
To set up a new identification and analysis method of Spora Lygodii.
METHOD
To get the extracts of Spora Lygodii using methanol, chloroform and petroleum ether as solvent and the extracts were identified, analyzed by X-ray diffraction Fourier fingerprint spectra.
RESULTS
Experiments and analysis were carried out on three samples. The standard X-ray diffraction Fourier fingerprint spectra and characteristic diffraction peaks were obtained. There were some differences among the spectra of the extracts, but the characteristic diffraction peaks were obvious.
CONCLUSION
The experimental result indicated that X-ray diffraction Fourier fingerprint spectra can be used to identify and analyze the Chinese traditional herb Lygodium japonicum (Thunb.) Sw.
目的
建立海金沙新的鉴别与分析方法。
方法
以甲醇、氯仿和石油醚为溶剂获取海金沙提取物，并采用X射线衍射傅里叶指纹图谱对提取物进行鉴别与分析。
结果
对3个样品进行了实验与分析，获得了标准X射线衍射傅里叶指纹图谱及特征衍射峰。提取物的图谱之间存在一些差异，但特征衍射峰明显。
结论
实验结果表明，X射线衍射傅里叶指纹图谱可用于鉴别与分析中药海金沙。
