Biopolymers based on the pequi oil (Caryocar brasiliense Cambess) were synthesized in order to be implemented as drug vehicles. The polymers were characterized by various techniques. Associated with these techniques were the release tests (diclofenac sodium - DS) at pH 1.2 and pH 7.4. According to the results, the technique of FTIR and 1H NMR prove the effectiveness of the synthesis; the XRD technique...
In this study, we have developed phenolic acid grafted chitin-glucan complex via new, simple and effective free radical mediated method by using gallic acid (GA) and chitin-glucan complex. The chemical structure of Gallic acid grafted chitin-glucan complex (GA-g-chitin-glucan complex) was characterized by proton nuclear magnetic resonance (1H-NMR) and Fourier-transform infrared spectroscopy (FT-IR)...
