Chemical composition and biological activities of the essential oils from Vitex-agnus castus, Ocimum campechianum and Ocimum carnosum Anais da ABC (AABC)
RICARTE,LARA P.; BEZERRA,GABRIELI P.; ROMERO,NIRLA R.; SILVA,HORLANDO C. DA; LEMOS,TELMA L.G.; ARRIAGA,ANGELA M. C.; ALVES,PÉRICLES B.; SANTOS,MARCELO B. DOS; MILITÃO,GARDENIA C.G.; SILVA,THIAGO D.S.; BRAZ-FILHO,RAIMUNDO; SANTIAGO,GILVANDETE M.P..
Abstract The essential oils obtained by hydrodistillation from fresh leaves of Vitex agnus-castus and Ocimum campechianum, and from fresh inflorescences of Ocimum carnosum were analysed by GC-FID and GC-MS. The major components of V. agnus-castus essential oil were identified as 1,8-cineole (47.9%), terpinyl α-acetate (11.6%), sabinene (11.2%) and caryophyllene oxide (9.7%), while in the O. campechianum essential oil were eugenol (72.1%), β-elemene (6.8%), (E)-caryophyllene (6.4%) and bicyclogermacrene (5.2%). Linalool (79.0%), α-epi-cadinol (5.4%), terpinen-4-ol (3.2%) and 1,8-cineole (2.8%) were the major constituents in the O. carnosum essential oil. The essential oils were subsequently evaluated for their larvicidal and cytotoxic activities. Larval...

Isolation, characterization and evaluation of antimicrobial and cytotoxic activity of estragole, obtained from the essential oil of croton zehntneri (euphorbiaceae) Anais da ABC (AABC)
ANDRADE,THALLITA C.B.; LIMA,SIDNEY G. DE; FREITAS,RIVELILSON M.; ROCHA,MÁRCIO S.; ISLAM,TOREQUL; SILVA,TERESINHA G. DA; MILITÃO,GARDENIA C.G..
Croton zehntneri (Euphorbiaceae) is a native aromatic plant from Northeast region of Brazil. The monoterpenoid estragole (ESL) has been isolated by classical chromatographic methods from the essential oil (EO) of C. zehnteneri leaves and characterized by GC-FID and GC-MS, its antimicrobial and cytotoxic potentials being assessed. The analysis of the EO enabled the identification of 100% of the integrated constituents, of which yield was about 1.8%. The main components identified were: eucalyptol, estragole (84.7%) and spathulenol. The dosage of 50 μg/disk of ESL presented fairly significant zones of inhibition against Gram-positive bacteria and fungi. The ESL presented toxicity against Artemia salina with LC50 and LC90 of 4,54 and 8,47 μg mL-1. However, in...
