Comparative analysis of chemometrics between exocarp and mesocarp of Citrus grandis'Tomentosa'
摘要
Abstract
The study is to analyze the differences in chemical components between the exocarp of Citrus grandis'Tomentosa'(WP)and mesocarp of C.grandis'Tomentosa'(ZP),and provide a basis for the full utilization of C.grandis'Tomentosa'resources.The UPLC-Zone TOF-MS/MS technique was used to identify the chemical substances in the WP and ZP.Principal component analysis(PCA)and orthogonal partial least squares discriminant analysis(OPLS-DA)were applied to compare and analyze the above data.Potential differential markers were screened based on the criteria of variable importance in the projection(VIP)>1 and P≤0.05,and the contents of these markers were determined by HPLC.The results showed that the types of chemical components in the WP and ZP were relatively similar,but there were significant differences in their contents.The discrete trends of the two groups of samples were obvious,with the WP clustered into one category and the ZP into another.OPLS-DA analysis indicated that Naringin,Rhoifolin,Vicenin-2,and Meranzin hydrate were the main marker substances distinguishing the two groups of samples.Quantitative analysis showed that the content of Naringin in both groups was much higher than that of other components.The content of Naringin in the ZP was significantly higher than that in the WP,while the contents of Rhoifolin,Vicenin-2,Meranzin hydrate,Isoimperatorin,and Bergapten in the ZP were significantly lower than those in the WP.ZP is rich in flavonoid active ingredients and possesses significant medicinal and health benefits.关键词
