“…This result was consistent with the research of Karimirad et al stated that encapsulation of essential oil by chitosan nanoparticles can extend shelf life and there are more antioxidant enzymes than controls [7]. The increased antioxidant activity is also caused by chitosan which has hydroxyl and amine groups which can prevent free radical chain reactions [13,20,21].…”

“…The mixture was homogenized at a speed of 1000 rpm for 24 h in a room temperature. After being homogeneous, 0.01% of NaTPP was added as much as 3.5 ml drop by drop then stirred again for 3 h. The nanoparticle produced was characterized by Particle Size Analyzer [PSA] to determine the particle size distribution and zeta potential to determine its stability [13].…”

Objective: The aim of this study was to determine the antioxidant activity of Chromolaena odorata. Methods: Encapsulation of Chromolaena odorata leaf extract by nano chitosan was synthesized by using chitosan and NaTPP as the crosslinking agent. The antioxidant activity was conducted by using the DPPH method. Results: Nanoparticles of Chromolaena odorata leaf extract has an average diameter of 675±218 nm and+23.4±7.14 mV of zeta potential. The antioxidant activity of its extract was 0.86 ppm, while its nanoparticle has the better antioxidant activity of 0.21 ppm. Conclusion: Nanoparticles of Chromolaena odorata have very strong antioxidant activity and the potential to be external antioxidants.
