Orthogonal partial least square discriminatory analysis (OPLS-DA) score plot showing the predictive (t[1]) and orthogonal (to [1]) components of ¹H-NMR spectral data of M. oleifera (cultivar PKM1) metabolites profile under low/intermediate and high harvesting frequencies, showing three distinct clusters (R²X = 0.832; R²Y = 0.643; Q² = 0.371). R²X, R²Y, and Q² represent the cumulative values of all the components of the model. Low and intermediate harvest frequency (red circled), high harvest frequency (blue circled), and low and intermediate frequency samples harvested in April and May (green circled). H-30 days harvesting frequency; I-60 days harvesting frequency; L-90 days harvesting frequency; Jan-a = January, A = April, Mar = March, May = May, Oct = October, Nov = November, Dec = December; Jan-b–January of the next year. R²X[1] = 0.472; R²Xo[1] = 0.358.
