GC-MS Fingerprint of Petroleum Ether Fraction in Paulownia fortunei Leaves
摘要
Abstract
To evaluate the quality of Paulownia fortunei leaves from different regions,gas chromatogra-phy-mass spectrometry was used to qualitatively analyze the petroleum ether fraction of Paulownia for-tunei leaves.Squalene used as a control,the similarity evaluation system of traditional Chinese medicine chromatographic fingerprint(2012A version)used for similarity evaluation,cluster analysis and principal component analysis were combined to evaluate the quality.The results indicated that a total of 12 com-mon peaks were identified in 19 batches of Paulownia fortunei leaves from various regions.These peaks corresponded to the following compounds:4,4,7a-Trimethyl-5,6,7,7a-tetrahydro-1-benzofuran-2(4H)-one,phytol,heptadecanoate,2-methyl octacosane,squalene,nonacosane,triacontane,hexatriacontane,α-Tocopherol,nonatriacontane,tetracontane,β-Sitosterol.Through cluster analysis,19 batches of Paulow-nia fortunei leaves were divided into 3 major categories.The cumulative variance contribution rate of the two principal components obtained from principal component analysis was 86.725％,and the results showed that sample S12 had a higher comprehensive score.The results of principal component analysis and cluster analysis were basically consistent.关键词
