Support vector machine and PCA for the exploratory analysis of Salvia officinalis samples treated with growth regulators based in the agronomic parameters and multielement composition

•Salicylic, gibberellic and abscisic acid influences the minerals absorption in salvia.•The application of growth regulators favored the production of photoassimilates.•Aplication of support vector machine for the exploratory analysis of Salvia samples.•Salvia samples were classified based on elemental composition, total flavonoids, and phenolic or agronomic variables.
