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.
