Preparation of nanosilica-immobilized antioxidant and the
3,5-Di-tert-butyl-4-hydroxybenzoic acid is not a high efficiency antioxidant and often used as an intermediate to prepare other kinds of antioxidant and light stabilizer. In the present work, the immobilized antioxidant (SiO 2 -APTMS-AO) was prepared by grafting 3,5-di- tert -butyl-4-hydroxybenzoic acid onto silica nanoparticle which acted as solid support.

Antioxidant behaviour of a nanosilica-immobilized
In our previous work, reactive antioxidants were chemically immobilized onto a nanosilica surface [25]. The efficiency of the nanosilica-immobilized antioxidant has been evaluated in low density polyethylene (LDPE) by the DSC method.

Antibacterial, Antioxidant, and Anticholinesterase
The antimicrobial, antioxidant, and anticholinesterase activities of ethanolic seed extracts of twenty-one plant species from Brazilian semiarid region were investigated. The extracts were tested for antimicrobial activity against six bacteria strains and three yeasts.

Screening of Brazilian plant extracts for antioxidant
Brazilian plant extracts belonging to 16 species of 5 different families (71 extracts) were tested against. the stable DPPH (2,2-diphenyl-1-picryl-hydrazyl-hydrate) free-radical. The ability to scavenge DPPH. radical was measured in these experiments by the discoloration of the solution.
