Oil palm (Elaeis guineensis Jacq.) is a crop that has great economic potential, since its productive potential is extremely high. It is grown in several countries in Asia, Africa and South America, with the main purpose of producing biodiesel raw material for the cosmetics and food industry. In Brazil, its cultivation is concentrated in only a few small regions, distributed mainly in the Northeast and North of the country. However, in spite of the few areas with commercial cultivation, the oil palm has potential of planting in other diverse areas such as the plantations of São João da Baliza in the of Roraima state. Sample collection was in São João de Baliza city, Roraima (Brazil). The pulp of fruit was taken out and dried in an oven with air circulation, material was milled and sieved to 20-40 Mesh. The lipid was obtained by Soxhlet and hexane as solvent. The lipid yield was 21.34%. The lipid analysis was on HP5890 gas chromatograph equipped with flame ionization detector, GC-FID. Eleven fatty acids were identified, where the majority were UFA were ?-9 (32.68%), ?-6 (8.34%) and ?-3 (0.29%) and the majority SFA were palmitic (44.16%) and palmitoleic acid (0.17%). The concentration of total carotenoids in the pulp from where were 587±0.21 mg kg-1 and the antioxidant activity by the DPPH method was 44.17 ± 0,12 % and by the iron reduction method of 117.31 ± 0.21??mol FeSO4100g-1 and the total phenol compounds in the palm oil pulp was 4.19 ± 0.32 mg GAE g-1.

A novel series of copper(II) derivatives of bis(pyrimidin-2-ylthio)- and bis(4,6-dimethylpyrimidin-2-ylthio)alkane of general formula [CuxCly(L)z]n {x = 1, y = 2, z = 1, L = ptm (1), pte (2), dptm (4), dpte (5), dpth (6); x = 2, y = 4, z = 3, L = pth (3) were tested for antimicrobial activity. These complexes were characterized by elemental analysis, infrared spectroscopy (IR) and gel permeation chromatography (GPC). Complex-4, 5 and 6 have the metal at the center of a square planar geometry and in complex-1, 2 and 3 the metal is at the center a square pyramidal geometry. The structure of complex-4, determined by X-ray diffraction analysis, shows this compound as an oligomer with one-dimensional chain in zigzag conformation. The high average molecular mass (Mw) of these copper(II) complexes confirms their oligomeric character. Although the free ligands were inactive agaisnt the microorganisms tested, the copper(II) derivatives showed good antifungal and antibacterial inhibition against C. albicans, C. tropicalis, S. aureus and E. coli, more effective than Nystatin and Norfloxacin.
