巨尾桉挥发油的气相色谱指纹图谱研究

摘要

A chromatographic fingerprint method was used to analyze the quality evaluation and control of Eucalyputs grandis X E.urophylla. GC method was adopted and 12 peaks were picked out as characteristic peaks. This method is reliable,accurate with good reproducibility. The fingerprints revealed high characteristic and specificity,and the similarity analysis showed no difference, which provides a scientific base for controlling the quality of E. grandis X E. urophylla,%采用气相色谱及指纹图谱相似度评价法对巨尾桉(Eucalyputs grandis×E.uroph ylla)挥发油气相指纹图谱进行研究,用以评价与控制巨尾桉挥发油内在质量.结果建立了巨尾桉指纹图谱,确定12个色谱峰为共有峰.该方法的精密度、稳定性、重现性良好,其指纹图谱相似性高,特征性和专属性强,相似度分析显示无差异,利用特征指纹图谱可以对巨尾桉挥发油进行质量控制.
