摘要: 番石榴叶为桃金娘科植物番石榴(Psidium guajava Linn.)的干燥叶,主要分布于广东、广西、福建、海南、四川及云南等地。本研究通过高效液相色谱法(HPLC)指纹图谱对不同产地的番石榴叶进行质量评价。采用相似度评价、聚类分析、主成分分析和正交偏最小二乘法-判别分析对指纹图谱数据进行统计分析。结果表明31批番石榴叶样品确定了14个共有峰,其相似度处于0.720~0.928,其中相似度小于0.8的番石榴叶样品主要产自广西、广东,相似度大于0.9的番石榴叶样品主要产自四川、云南;聚类分析及主成分分析提示番石榴叶样品可根据产地大致分为两类,包括沿海地区(广西、广东、福建、海南)和西南地区(四川、云南),不同产地番石榴叶药材质量存在差异;正交偏最小二乘法-判别分析结果表明9、4、12、11、13、3、10号峰是引起番石榴叶产地质量差异的主要成分,并鉴定出9号峰为鞣花酸,11号峰为异槲皮苷,13号峰为番石榴苷,12号峰为瑞诺苷,10号峰为金丝桃苷。定量分析鞣花酸、异槲皮苷、番石榴苷、瑞诺苷、金丝桃苷发现西南地区的5种成分总量高于沿海地区,具有显著性差异。本研究建立的番石榴叶HPLC指纹图谱结合化学计量法的方法简便准确,可为番石榴叶质量控制和品质评价提供参考依据。

Abstract:

Psidii Guajavae Folium(PGF) are dry leaves of Psidium guajava Linn.A plant of Myrtle family,mainly distributed in Guangdong,Guangxi,Fujian,Hainan,Sichuan and Yunnan.In this study,the high performance liquid chromatography (HPLC) fingerprint was used to evaluate the quality of guava leaves from different habitats.Similarity evaluation,cluster analysis,principal component analysis and orthogonal partial least squares-discriminant analysis were adopted to analyze fingerprint data.The results showed that 31 batches of PGF have 14 common peaks with similarity ranged from 0.720 to 0.928,among which PGF with a similarity less than 0.8 were mainly produced in Guangxi and Guangdong,while those with a similarity more than 0.9 were mainly produced in Sichuan and Yunnan.According to the cluster analysis and principal component analysis,the samples of PGF could be roughly divided into two types in terms of the origin,namely coastal areas (Guangxi,Guangdong,Fujian,Hainan) and southwest areas (Sichuan,Yunnan),with differences in the quality of PGF from different origins.Orthogonal partial least squares method was used to screen out 7 components with quality differences,including ellagic acid,isoquercetin,guaijaverin,reynoutrin and hyperoside.According to the quantitative analysis of ellagic acid,isoquercetin,guaijaverin,reynoutrin and hyperoside,the total amount of the five components in southwest China outweighed that in coastal areas,which demonstrates a significant difference.In this study,the method combining the HPLC fingerprint of PGF with chemical measurement was simple and accurate,which could provide references for the quality control and evaluation of PGF.
