RESUMO

Plants differ in metabolism during their life cycle. In species used as phytotherapics, these changes determine the quality and effectiveness of the product. The aim of this study to evaluate the differences of chemical extracts obtained with supercritical CO2 from young and adult leaves of Zanthoxylum tingoassuiba St.-Hil., Rutaceae, a species used in the folk medicine in Brazil. The chemical composition of the extracts was elucidated by spectroscopic analysis and comparison with literature data. The results showed difference in the composition of the leaves from Z. tingoassuiba and allowed the determination of parameters for the extraction of α-bisabolol and furanocoumarins in this vegetal matrix.
