Provedor de dados: 42
Autores: CAMARA,CLAUDIO A.G. DA; MARSAIOLI,ANITA J.; BITTRICH,VOLKER.
Abstract The apolar fractions components of fruit latex of twelve species of Clusia belonging to four different taxonomic sections were examined by GC-MS. The latex of Clusia is characterised by large amounts of sesquiterpene hydrocarbons as major constituents like germacrene D: C. paralicola (44.28 %), C. criuva subsp. criuva (29.03 %); β-caryophyllene: C. fluminensis (35.61 %), C. lanceolata (36.39 %), C. hilariana (58.10 %); α-trans-bergamontene: C. spirictus-sanctensis (36.30 %); α-bulnesene: C. weddelliana (25.61 %); bicyclogermacrene: C. panapanari (25.93 %) and trans-β-farnesene: C. nemorosa (24.63 %), while C. grandiflora is composed of 42.16 % monoterpene hydrocarbons. Verbenone (31.91 %) was the major component. In contrast, C. rosea, C....

ABSTRACT Essential oils from the leaves of two species of the genus Ocotea that occur in the Atlantic Forest in the state of Pernambuco, Brazil, were analyzed using gas chromatography-mass spectrometry. The acaricidal activity of these oils as well as 11 selected components and blends were evaluated in fumigation and residual contact tests against the two-spotted spider mite (Tetranychus urticae). Sixty-seven constituents were identified, totaling 97.3 ± 0.3% and 97.8 ± 0.5% of the oils from O. duckei and O. glomerata, respectively. Sesquiterpene was the dominant class. The compounds β-caryophyllene (18.6 ± 0.1%) and aromadendrene (17.3 ± 0.6%) were the main constituents of the oils from O. duckei and O. glomerata, respectively. Acaricidal action varied...
