SUMMARY:

Pentaclethra macroloba (Willd.) Kuntze is an oilseed species that occurs naturally in the states of Amapá, Amazonas and Pará, popularly known as pracaxi. Found in floodplain forest, igapó and upland forests. The oil from its seeds has aroused great interest in the industry, especially for cosmetics. In addition to being able to be used for ecological purposes in forest conservation and recovery. Therefore, describe the anatomical and histochemical aspects and the composition of the photochemical profile of the seeds of Pentaclethra macroloba (pracaxi). The fruits were identified from matrices of three populations located in the municipalities of Belém, Marituba and Domingos do Campi. The seeds were removed from the fruits manually. For the anomic study, and microscopy, seeds, cross-sectioned and electronically scanned for embryonic axis and chemically 70 to embryonic axis 5% chemical in FAA 50%, TNF, and electronic stored in 5% ethyl alcohol. For the anatomical study, the seeds were changed to the usual techniques of plant anatomy. Histochemical testswere performed on manual sections and included in paraplast, free dyes and specific reagents. Atomically, the seed coatof P. macroloba is formed by exotesta (external epidermis), mesotesta (mesophyll) with idioblasts and endotesta (internal epidermis). its vascular effects. The rubberized protoderm is uniseriate, covered by rectangular cells and covered by a cuticle. The ones with the highest concentration are; P. macroloba are; oleic acid, behenic acid, lignoceric acid, linoleic acid. Therefore, the presented P. macroloba seeds. Pentaclethra macrolobaal seeds have anatomical characteristics to distinguish the species within the fabaceae subfamily and the fabaceae family and its oil is rich in essential fats for human health, such as fatty acids belonging to the omega family (Linoleic, Oleic).
