Abstract
⺠UPLC analysis enabled reduction of time and solvent consumption about 10 times. ⺠Overall, leaves grown in the sun had a greater content of bioactive compounds. ⺠Processed leaves showed a decrease in the concentration of xanthines with in natura. ⺠Oxidised leaves had a lower concentration of phenolics when compared with in natura.
