不同茎叶比例的穿心莲药材中穿心莲内酯与脱水穿心莲内酯的X射线衍射定量分析方法的探讨

A quantitation method for andrographolide and dehydroandrographolide by X-ray powder diffraction Fourier fingerprint pattern technique

穿心莲中药材为爵床科植物穿心莲Andrographis paniculata（Burm.f.）Nees的干燥地上部分。秋初茎叶茂盛时采割,晒干。性味苦、寒,归心、肺、大肠、膀胱经,具有清热解毒、凉血、消肿的功能。穿心莲属常用中药材,

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.
