Phytochemical and antioedematogenic studies of commercial copaiba oils available in Brazil

Abstract: The composition of eight samples of commercial copaiba oils, used in the Amazonian region as antiinflammatory agents and available in popular markets, were analysed by gas chromatography/mass spectrometry (HRGC-MS). Major differences were observed in their chemical composition and some adulterations were pointed out. When tested in vivo oils 1 and 3, and to a lesser extent oil 6, significantly inhibited bradykinin-induced oedema formation. The other tested oils had no effect. When assessed in carrageenan-induc… Show more

“…Estudos recentes realizados com diversos óleos de copaíba comerciais 201 e de Copaifera multijuga mostram que a fração que contém hidrocarbonetos tem maior atividade antiinflamatória do que as frações de álcoois sesquiterpênicos e ácidos diterpênicos.…”

“…These include tannins, alkaloids, saponins, flavonoids, sterols, terpenoids and reducing sugars (Galvez et al, 1993;Mukherjee et al, 1998;Otshudi et al, 2000;Shoba, 2001;Havagiray et al, 2004;Venkatesan et al, 2005). Flavonoids and saponins are known to inhibit the release of autocoids and prostaglandins thereby reducing the motility and secretion induced by castor oil (Veiga et al, 2001;Perez et al, 2005). Because many of these compounds might have antidiarrheal effects, it is difficult to suggest which of them is responsible for the desired effect.…”

“…Another example is given by May and Barata (2004), in which the oil produced in the idioblasts of Aniba rosaeodora (Lauraceae) stem and leaf has a similar chemical composition. Therefore, comparative studies of the production, storage, and release of the oleoresin in each plant organ are essential in order to avoid the predatory extraction of economically important substances in the stem, especially due to the great exploitation of the forest species for economic purposes (Veiga et al 2001).…”
