The powder X-ray diffraction Fourier fingerprint pattern technique was used to develop a new quantitation method for the analysis of andrographolide and dehydroandrographolide. And the high performance liquid chromatography method was used to evaluate the quantity of andrographolide and dehydroandrographolide. The relationship of diffraction peak intensity and content of andrographolide and dehydroandrographolide was investigated. The powder X-ray diffraction Fourier fingerprint pattern analysis technique can be used to evaluate the quantity of andrographolide and dehydroandrographolide in the herb simultaneously.
采用粉末X射线衍射傅里叶指纹图谱技术建立了一种新的穿心莲内酯和脱水穿心莲内酯定量分析方法。并采用高效液相色谱法对穿心莲内酯和脱水穿心莲内酯的含量进行测定。研究了穿心莲内酯和脱水穿心莲内酯衍射峰强度与含量之间的关系。粉末X射线衍射傅里叶指纹图谱分析技术可用于同时评价穿心莲中穿心莲内酯和脱水穿心莲内酯的含量。
