摘要
目的基于高效液相色谱(HPLC)指纹图谱结合化学计量法,评价广西鹅掌柴的质量。方法采用HPLC法,流动相为甲醇-0.1%磷酸溶液进行梯度洗脱,对10个不同产地广西鹅掌柴进行指纹图谱研究,采用聚类分析(CA)、主成分分析(PCA)和正交偏最小二乘-判别分析(OPLS-DA)对其质量进行评价。结果建立了10个不同产地广西鹅掌柴指纹图谱,共标定22个共有峰,相似度为0.922~0.999,并指认了4个色谱峰(红景天苷、4,5-二-O-咖啡酰奎宁酸、咖啡酸、柚皮素),CA与OPLS-DA分析可将不同产地广西鹅掌柴大致分为四类,主成分分析筛选出的4个主成分累计贡献率达到95.39%。结论通过指纹图谱结合CA、PCA、OPLS-DA分析可全面综合评价广西鹅掌柴质量,为广西鹅掌柴的质量控制进一步评价提供参考。
Objective Based on HPLC fingerprinting and chemometrics,to evaluate the quality of Schefflera kwangsiensis Merr.from Guangxi.Methods HPLC was used to establish fingerprints of Schefflera kwangsiensis Merr.from ten different origins,and gradient elution was carried out with methanol-0.1%phosphoric acid aqueous solution as mobile phase.Cluster analysis(CA),principal component analysis(PCA)and orthogonal partial least squares-discriminant analysis(OPLS-DA)were applied to evaluate quality.Results The fingerprints of Schefflera kwangsiensis Merr.from ten different origins were established by HPLC,a total of 22 common peaks were calibrated,with a similarity range of 0.922-0.999.Four chromatographic peaks were identified as rhodopsin,4,5-bis-O-caffeoylquinic acid,caffeic acid,and naringin.The samples were classified into four types according to the CA and OPLS-DA.PCA identified four principal components with a cumulative contribution rare of 95.39%.Conclusion The quality of Schefflera kwangsiensis Merr.can be comprehensively evaluated by fingerprinting combined with CA,PCA and OPLS-DA analysis.The Study can provide a reference for improving the quality control and assessment of Schefflera kwangsiensis Merr.
