Abstract
Ocotea odorifera (Vell.) Rohwer is popularly used as food and flavoring. The aim of this study was to determine
the chemical composition of the aqueous extract from O. odorifera leaves and evaluate the correlation
of their phytochemical composition and biological activities. The antioxidant effect was determined
by DPPH radical scavenging, b-carotene-linoleic acid and lipid peroxidation assays; the antibacterial
activity was evaluated by the hole plate and MIC techniques and the antimutagenic activity was evaluated
by the Ames test. Identification of phytochemicals was performed by LC–ESI/MS and the correlation
between the phytochemical composition of the extract and the evaluated activities. The results allowed
the identification of 13 phenolic compounds in the extract that exhibited high antioxidant activity and
moderate antibacterial and antimutagenic action. Statistical analyses showed correlation of the total phenolic
content with biologically related activities. The phytochemical analyses, together with the biological
results, support the popular use of O. odorifera.
