Chemical composition and acaricidal activity of the essential oils from fruits and leaves of protium bahianum daly / Wendel J.T. Pontes in The journal of essential oil research, Vol. 22 N° 3 (Mai/Juin 2010)

Twentynine components were identified in the oils. The main component of the fruit oil was a-pinene (34.0%) whereas aromadendrene (20.3%) was the major component of the leaf oil. The leaf oil exhibited a higher lethality rate with LC50 of 3.5 mL/L of air after 24 h exposure. The fruits oil showed LC50 of 9.1 mL/L of air and was repellent at 1% concentration.

Composition and acaricidal activity of the resin's essential oil of protium bahianum daly against two spotted spider mite (Tetranychus Urticae) / Wendel J.T. Pontes in The journal of essential oil research, Vol. 19 N°4 (Juillet/Août 2007)

Twenty-two and thirteen components were identified in the oils from fresh and aged resins, comprising 95.8 % and 98.6 %, of the oils, respectively. The aged resin oil contained a high percentage of oxygen-containing sesquiterpenes (85.4 %) with a high predominance of β-(Z)-santalol acetate (83.1 %). In contrast, no sesquiterpenes were detected in the fresh resin oil and it was constituted basically by monoterpenes hydrocarbons (42.4 %) and oxygen-containing monoterpenes (27.7 %), of which α-phellandrene (13.9 %) and terpinen-4-ol (7.4 %) were the major components, respectively. The acaricidal activities against Tetranychus urticae of the resin oil were also investigated. Both oils showed fumigant toxicity (mortality and fecundity), but only the aged resin oil induced repellence.
