【摘要】 目的研究比较3种郁金挥发油成分的指纹图谱,并采用指纹图谱相似度评价软件计算其相似度,为郁金药材质量控制标准提供依据。方法采用GC色谱法建立指纹图谱,并用GC-MS色谱法确定指纹图谱特征峰,采用指纹图谱全谱相似度计算方法评价指纹图谱的相似性。结果不同品种郁金的指纹图谱既有相似性,又有其特征性,指纹图谱检测方法学验证结果良好,RSD均2.53%。结论该方法可用于鉴别不同品种郁金,具有简便、准确、专属性强等特点,能更科学有效地控制中药材郁金的质量。更多还原

【Abstract】 Objective The fingerprint of volatile components from three breeds of Radix Curcumae was compared to supply evidence for the standard of quality control of Radix Curcumae.Methods Gas chromatography was used to establish fingerprint of Radix Curcumae and GC-MS chromatography was applied to identify its characteristic peaks. The similarity of fingerprint was evaluated by computing method.Results The fingerprint had its similarity and characteristics in different breeds of Radix Curcumae. The fingerprint detection is a good method for identifying Radix Curcumae,RSD 2.53 %.Conclusion This method is simple and effective for identifying different breeds of Radix Curcumae and can be used to control the quality of medicinal material of Radix Curcumae.更多还原
