From: Assessment of geographical origin and production period of royal jelly by NMR metabolomics
PCA score-plots based on 1H NMR spectra of Royal Jelly samples produced by three Grosseto farms (Gr3, circles, a; Gr4, squares, b; Gr5, triangles, c in different days (see legend). Total variance explained by the score-plots shown in Figs A, B and C corresponds to 37.5, 18.7 and 40.1%, respectively. The ellipses were arbitrarily generated to indicatively group the different RJ types. The name and orthogonal direction of most significant loading vectors involved in the differentiation among RJ types are reported along the plot borders (more details are reported in Supporting Fig. S11)
