Evaluation of Yield, Chemical Composition and Antioxidant Capacity of the Essential Oil From Leaves and Fruits (Seed and Bark) of Virola sebifera Aubl. (Myristicaceae)

Flavour and Fragrance Journal, EarlyView.
In the study of V. sebifera plant organs, the leaves exhibited the highest EO content, with peak production in February, the Amazonian winter. Notably, among the various plant parts yielding EO, the fruit peel contained the highest oil concentration. ABSTRACT The essential oils (EOs) of Virola sebifera were obtained from leaves, seed fruits and husked ...

Chemometrics and Modeling

CHIMIA, 2001
Chemometrics is a chemical discipline in which mathematical and statistical techniques are applied to design experiments or to analyze chemical data. An important part of chemometrics is modeling, in which one tries to relate two or more characteristics in such a way that the obtained model represents reality as closely as possible.
