Abstract

This study aims to obtain mesocarp films of Orbignya sp. (MB) and carboxymethylcellulose (CMC) for application as a drug release matrix. Tannic acid (TA) was used as a standard drug. The films were evaluated by infrared, swelling power, TA release profile, bioactivity and in vitro cytotoxicity. Infrared results indicated absorption at 1.205 cm-1, which is characteristic of ester group from the incorporated tannin. The MB-CMC film had 449.15% swelling power, release of 71.01% of TA of the matrix after 24 h. Films showed scavenger activity of radicals DPPH (79.07 ± 1.71% to 82.17 ± 1.94%) and ABTS+ (82.20 ± 0.30% to 88.90 ± 1.05). The MB-CMC film also showed in vitro cytotoxicity on sarcoma-180 (91.86 ± 9.97%) and on promastigote forms of Leishmania major (100%). Polymers showed good compatibility in the mixture and the results suggest the films obtained are promising as drug release matrices.
