In plant cell cultures aiming at the production of secondary metabolites of industrial interest,
the culture medium composition is a decisive step for obtaining cell growth and high yields of the target compound(s).
A rapid and reliable methodology for screening metabolic responses to medium composition is fundamental for the development
of this biotechnological field. Following this approach, UV-Vis scanning spectrophotometry of callus extracts and their
spectra pre-processing, univariate and multivariate analysis were tested in the present work. The results obtained successfully
discriminated the culture media investigated and shed light on what metabolic pathways might be responsible for the differences
among the callus cultures' metabolic profiles.
