چکیده
ABSTRACT Pera-do-cerrado (Eugenia klotzschiana O. Berg) has a good appearance and adequate post-harvest shelf life. However, little information is available regarding its maturity stages. This study aimed at characterizing E. fruits harvested three stages (immature, physiological mature ripe), in addition to evaluating the physical chemical changes during storage ambient temperature (24 ± 2 ºC 75 % 5 of RH) for up days. The ripe had higher fresh mass (98.03 g), width (5.61 cm) ratio (5.37), lower titratable acidity (1.27 %). In contrast, immature showed greener peel (101.32 ºh) vitamin C content (11.23 mg 100 g-1). There was an increase weight loss (3.05 %) decrease luminosity (67.09-57.12 L*) (8.11-5.04 soluble solids (SS) values did not change days storage. A reduction (TA; 1.29-1.06 also observed, which resulted (3.81-5.84). conclusion, should be ripe, as they present larger dimensions, better color, SS/TA (flavor) are less acidic.

Chemical composition, antioxidant and antibacterial activities of essential oils from leaves and flowers of Eugenia klotzschiana Berg (Myrtaceae).
Many essential oils (EOs) of different plant species possess interesting antimicrobial effects on buccal bacteria and antioxidant properties. Eugenia klotzschiana Berg (pêra-do-cerrado, in Portuguese) is a species of Myrtaceae with restricted distribution in the Cerrado. The essential oils were extracted through the hydrodistillation technique using a modified Clevenger apparatus (2 hours) and ...

The chemical composition of volatile oils from two Myrtaceae species, Myrceugenia myrcioides and Eugenia riedeliana, both native from the Brazilian Atlantic Rain Forest, was analyzed by GC-MS. Acetylcholinesterase inhibitory activity was colorimetrically evaluated for these oils. For M. myrcioides, monoterpene hydrocarbons represented the major class in the volatile oil, with α-pinene as the mo...

Chemical and biological evaluation of essential oils from two species of Myrtaceae - Eugenia uniflora L. and Plinia trunciflora (O. Berg) Kausel.
The chemical composition and antimicrobial activity of essential oils obtained from leaves of two Myrtaceae species-Eugenia uniflora L. and Plinia trunciflora (O. Berg) Kausel-were determined. Analysis by GC/MS as well as determination of Kovatz indexes indicated atractylone (26.78%) and curzerene (17.96%) as major constituents of E. uniflora oil and α-cadinol (19.15%), apiole (11.15%) and cube...
