Circadian and seasonal variation in the essential oil from Virola surinamensis leaves
Phytochemistry, 1997Abstract The essential oil from leaves of Virola surinamensis shows circadian variation in elemicin and in monoterpenes during the rainy season (February). The monoterpenes represents 50% of total volatile compounds during the dry season (June). Sesquiterpenes are predominant (50%) in the early rainy season (October).
