“…In terms of the chemical composition of essential oils, there are certain molecules with phenolic structure like carvacrol whose concentrations affect the total phenolic content. But the total phenolic content is not explainable simply based on phenol molecules, due to the fact that the Folin-Ciocalteu reagent measures reducing agents, and essential oils present different kind of molecules with reducing capacity (Lester et al, 2012). The chemical composition of laurel EO did not show phenol structures.…”

“…The total phenolic content was determined using a modified procedure of Medina and Lester [46,47]. A total of 1 mL of 0.05 M sodium phosphate buffer (pH 7.4) was added to a microcentrifuge tube filled with 50 mg of ground cotton fibers, ~80 mesh.…”

Greige cotton is an intact plant fiber. The cuticle and primary cell wall near the outer surface of the cotton fiber contains pectin, peroxidases, superoxide dismutase (SOD), and trace metals, which are associated with hydrogen peroxide (H2O2) generation during cotton fiber development. Traditionally, the processing of cotton into gauze involves scouring and bleaching processes that remove the components in the cuticle and primary cell wall. The use of unbleached, greige cotton fibers in dressings, has been relatively unexplored. We have recently determined that greige cotton can generate low levels of H2O2 (5–50 micromolar). Because this may provide advantages for the use of greige cotton-based wound dressings, we have begun to examine this in more detail. Both brown and white cotton varieties were examined in this study. Brown cotton was found to have a relatively higher hydrogen peroxide generation and demonstrated different capacities for H2O2 generation, varying from 1 to 35 micromolar. The H2O2 generation capacities of white and brown nonwoven greige cottons were also examined at different process stages with varying chronology and source parameters, from field to nonwoven fiber. The primary cell wall of nonwoven brown cotton appeared very intact, as observed by transmission electron microscopy, and possessed higher pectin levels. The levels of pectin, SOD, and polyphenolics, correlated with H2O2 generation.

A novel method was designed for the synthesis of polyphenol capped amorphous iron oxide nanoparticles (ION) using an agro waste (peanut skin). The synthesized nanoparticles were characterized by absorption spectroscopy, TEM, SEM, IR, Raman and XRD. An increased rate of formation of the nanoparticles is observed upon low dose gamma irradiation. ION shows specific spectral features with perchlorate anion even in presence of other anions selected for the anion sensing study. The nanoparticles formed in presence of irradiation was found even more sensitive to lower concentration of perchlorate owing to its finely dispersed nature and increased surface area.
