(A) Principal Component Analysis (PCA) of metabolic profiles in mulberry leaves. (B) Score plots generated from Orthogonal Partial Least Squares Discriminant Analysis (OPLS-DA) of metabolic profiles in mulberry leaves. (C–D) Cluster analysis of differential metabolites in the second (C) and fifith leaves (D) of EP and EW. QC, quanlity control samples. After the sample extraction, all samples of equal volume are taken and then mixedBack to article page
