SUMMARY:

Protium heptaphyllum (AUBL.) March is a native species of Brazil with medicinal properties and pharmacological potential, and vegetable tannins are secondary compounds that act in the treatment of different diseases. The objective of this work was to evaluate the characteristics and composition of the bark, leaf and fruit of the species, as well as the number of tannins in each structure. The content of moisture, ash content, volatile content and fixed carbon, as well the amount of crude protein, hemicellulose, lignin and cellulose were determined. Afterwards, extracts were obtained, evaluating in the samples the amount of total solid, Stiasny Index, condensed tannins and not tannins. Thermogravimetric analysis and Fourier transform infrared spectroscopy of the biomass and tanning extracts were also performed. The bark presented higher moisture content and ashes. The leaf was the structure that obtained higher amount of volatiles and the fruit a higher fixed carbon content. The leaf is the structure that has more crude protein and hemicellulose, and the lignin content was higher in the bark. The amount of cellulose is statistically the same for the three structures. The fruit contains a more significant amount of total solids, condensed tannins and no tannins, since the bark and leaf are structures that also have greater value in the Stiasny Index. The extracts showed different weight loss than biomass, and above 900 °C, the fruit has different thermal characteristics of the bark and leaf. Spectroscopy shows that the biomass and extracts of the three structures are similar.
