Fig. 3 in A H NMR-based metabolomic approach to study the production of antimalarial compounds from Psiadia arguta leaves (pers.) voigt

Fig. 3. (A) OPLS-DA score plot, (B) permutation plot, (C) ROC plot and (D) S-plot generated from the 1H NMR spectra (600 MHz) of healthy and attacked P. arguta plantlets crude extracts. (E) Contribution plot generated from the comparison of spectral variables of attacked samples vs healthy samples. The labels 6, 7, 8 and 9 on the PCA score plot correspond to the age of the plant; AA: attacked acclimatized plants; AH: healthy acclimatized plants and VH: healthy axenic plants.
