• Abstract:

  Macadamia (Macadamia integrifolia Maiden & Betche), is a non-timber forest crop introduced in Brazil, considered the queen of Nuts. Commercial interest in the species increased in the 1990s. The macadamia fruit has a cream-colored almond (walnut). A crop with an average return rate of 25%. The aim of this work was to evaluate the chemical profile of nutmeg residue (peel), in order to know the chemical composition and possible classes of metabolites. The analyzes were carried out from the peels. For the chemical composition, the contents of total extractives, holocellulose and Klason lignin were determined. Phytochemical analysis was performed to identify secondary metabolites in the hydroalcoholic extract. The quantitative results found were 1.25% of total extractives, 57.65% of holocellulose and 29.86% of Klason lignin. Phytochemical prospection revealed the presence of phenols and tannins, alkaloids, flavones, flavonols, xanthones, leucoanthocyanidins, catechins and flovonones. Thus, it was possible to characterize the chemical profile of the Nutmacadamia residue.
