TITLE:

"HISTOCHEMISTRY OF Pentaclethra macroloba (WILLD.) KUNTZE (FABACEAE) SEEDS FROM THREE NATURAL POPULATIONS IN THE EASTERN AMAZON"

KEY WORDS:

Anatomy, histochemistry, chemical profile, pracaxi.

BIG AREA: Ciências Biológicas
AREA: Botânica
SUMMARY:

Pentaclethra macroloba (Willd.) kuntze (Fabaceae), popularly known as pracaxi, is naturally found in floodplain, upland, and stream forests in the Amazon region, more specifically in the states of Amazonas, Acre, and Pará. Since it has useful chemical properties for the pharmaceutical and cosmetic sectors, it has been studied mainly regarding the composition of its oil, but the chemical profile nor its histochemistry have been described in the literature yet. In this context, the present work aims to determine the histochemical profile of Pentaclethra macroloba (Willd.) Kuntze (Fabaceae) seeds, from three natural populations of the Eastern Amazon, through the anatomical description of the structures present in the seed coat and embryo, and the chemical profile of the oil extracted by screw press and soxhlet. The ripe fruits were collected in three populations of Pentaclethra macroloba. The seeds will be subjected to anatomy, histochemistry, scanning electron microscopy (SEM); and the oils will be analyzed by gas chromatography (GC-FID). It is expected to determine the histological structures (trichomes, secretory cavities) responsible for storing the main classes of metabolites, and to obtain the chemical profile of the oil obtained by two extraction techniques.
