Chemical Composition and Antioxidant Activity of Essential Oils from Populations of Baccharis dracunculifolia DC. in Southern Brazil

Abstract

HIGHLIGHTS Essential oils from populations of B. dracunculifolia were investigated. β-pinene and (E)-nerolidol were the main compounds in B. dracunculifolia populations. The difference in the chemical profile of the essential oils is quantitative only. There is a negative correlation between the antioxidant activity and spathulenol.
