Chemical composition of the leaf oils from two morphotypes of Psidium cattleyanum at four phenological stages

Abstract

The chemical composition of volatile oil extracted from leaves of two morphotypes of Psidium cattleyanum Sabine from southern Brazil was evaluated at four phenological stages. In addition, plant material was evaluated at four different locations of the Planalto Serrano Region of Santa Catarina state, Brazil. Major components found were: 1,8-cineole, α-pinene, α-eudesmol, (E)-caryophyllene and p-cymene in red morphotype whereas 1,8-cineole, α-pinene, myrcene, (E)-caryophyllene and valerianol were found in the yellow morphotype. The differences observed in the chemical composition in red and yellow morphotypes may help in the differentiation between the two morphotypes in the absence of fruits. Also, important differences were observed mainly for 1,8-cineole and α-pinene percentage at different phenological stages.
