Antitermitic and antioxidant activities of heartwood extracts and main flavonoids of Hymenaea stigonocarpa Mart.

Adulteration and Contamination of Commercial Sap of Hymenaea Species

“…Despite the lack of studies performed on jatobá sap, these classes of compounds have been described in the wood bark of this plant species [17]. About the compounds found in the bark used for the present study; only procyanidins have been previously described in the literature on H. courbaril, the substitute species for H. stigonocarpa [33].…”

“…Among the compounds found in the control sap and jatobá stem bark, the main components were flavonoids and procyanidins, characterized by the molecular formula and the UV spectrum and compared to referential data. Despite the lack of studies performed on jatobá sap, these classes of compounds have been described in the wood bark of this plant species [ 17 ]. About the compounds found in the bark used for the present study; only procyanidins have been previously described in the literature on H. courbaril, the substitute species for H. stigonocarpa [ 33 ].…”

“…The species Hymenaea have a particular use in folk medicine when the sap of the trunk is used as a tonic [ 13 , 14 ]. Also, the stem bark of H. stigonocarpa has antidiarrhetic, gastroprotective and healing effect on gastric and duodenal ulcers [ 15 , 16 ], as well as antitermitic and antioxidant effect [ 17 ]. Among the compounds identified in this species, the terpenes of the epi-labdanoid type, present in the resin, were highlighted [ 18 ].…”

Extract of Bowdichia virgilioides and maackiain as larvicidal agent against Aedes aegypti mosquito

“…Earlier reports showed that wood extracts of B. virgilioides also contained alkaloids, terpenoids, steroids and different types of flavonoids (Arriaga et al, 2000;Thomazzi et al, 2010;Torrenegra et al, 1989); extracts of H. stigonocarpa contained flavonoids, terpenoids and steroids (Maranhão et al, 2013;Oliveira et al, 2010); and those of A. colubrina contained flavonoids, tannins, terpenoids and steroids . The choice of a different extraction procedure aimed to facilitate the preliminary fractionation of these constituents.…”

Phenolic Extractives and Natural Resistance of Wood

“…Several woods contain extractives which are toxic or deterrent for termites, bacteria and fungi resistance (Maranhão 2013;Taylor et al, 2006). Termite resistance of wood is a function of heartwood extractive variability while individual extractives inhibit fungal growth (Neya at al, 2004;Arango et al, 2006).…”
