Influence of the Extractive Method on the Recovery of Phenolic Compounds in Different Parts ofHymenaea martianaHayne.
BACKGROUND
Popularly known as "jatobá,"Hymenaea martianaHayne is a medicinal plant widely used in the Brazilian Northeast for the treatment of various diseases.


OBJECTIVE
The aim of this study was to evaluate the influence of different extractive methods in the production of phenolic compounds from different parts ofH. martiana.


METHODS
The leaves, bark, fruits, and seeds were dried, pulverized, and submitted to maceration, ultrasound, and percolation extractive methods, which were evaluated for yield, visual aspects, qualitative phytochemical screening, phenolic compound content, and total flavonoids.


RESULTS
The highest results of yield were obtained from the maceration of the leaves, which may be related to the contact time between the plant drug and solvent. The visual aspects of the extracts presented some differences between the extractive methods. The phytochemical screening showed consistent data with other studies of the genus. Both the vegetal part as the different extractive methods influenced significantly the levels of phenolic compounds, and the highest content was found in the maceration of the barks, even more than the content found previously. No differences between the levels of total flavonoids were significant. The highest concentration of total flavonoids was found in the ultrasound of the barks, followed by maceration on this drug. According to the results, the barks ofH. martianapresented the highest total flavonoid contents.


CONCLUSIONS
The results demonstrate that both the vegetable and the different extractive methods influenced significantly various parameters obtained in the various extracts, demonstrating the importance of systematic comparative studies for the development of pharmaceuticals and cosmetics.


CONCLUSIONS
The phytochemical screening showed consistent data with other studies of the genus HymenaeaBoth the vegetable part and the different extractive methods influenced significantly various parameters obtained in the various extracts, including the levels of phenolic compoundsThe barks ofH. martianapresented the highest total phenolic and flavonoid contents.
