Chemodiversity of Essential Oils From Eugenia uniflora L. Collected in Different Phytophysiognomies of the Coastal Region of Rio de Janeiro

Chemistry &Biodiversity, EarlyView.
Essential oils from Eugenia uniflora collected in different coastal phytophysiognomies of Rio de Janeiro showed notable chemodiversity. GC‐MS and GC‐FID analyses revealed nine chemotypes, mainly rich in curzerene and selina‐1,3,7(11)‐trien‐8‐one. ABSTRACT This study aimed to evaluate the yield, color, and chemical composition of Eugenia uniflora ...
