Chemical constituent analysis of the Babassu (Orbignya phalerata Mart.) mesocarp
The Babassu nut (Orbignya phalerata Mart.) mesocarp is traditionally transformed to flour and consumed in some Brazilian areas for its attributed medicinal activity; however, its chemical properties remain to be elucidated. The present work aimed at analyzing the babassu mesocarp phytochemical const...

The Babassu nut (Orbignya phalerata Mart.) mesocarp is traditionally transformed to flour and consumed in some Brazilian areas for its attributed medicinal activity; however, its chemical properties remain to be elucidated. The present work aimed at analyzing the babassu mesocarp phytochemical constituents. Babassu nut samples were collected in the Brazilian Amazon, and their mesocarps were prepared and macerated in different solvents. The chromatographic fractionation of selected methanol extracts yielded three fractions, A-5, A-6, and B-1 that were characterized with high resolution methods. Fraction A-5 was characterized through GC/MS as a fatty acid mixture with predominance of eicosanoic (38.67 %) and 11-octadecanoic (21.71 %) acids. Fraction A-6 was characterized by the presence of three phytosteroids (32.02 %), sesquiterpene (nerolidol; 24.89 %), and diterpene (17-acetoxy-19-kauranal; 15.17 %). The 1H and 13C NMR spectra on fraction A-6 showed characteristic chemical shifts for its compounds. Compound B-1 was identified as ergostanol-3-benzoate based on NMR experiments in one and two dimensions. These results constitute the first identification of babassu mesocarp chemical constituents in 1 and 2-dimensions, paving the way to understanding its role in popular medicine. |
