Antioxidant activity of mandarin (Citrus reticulata) peel [PDF]

Acta Periodica Technologica, 2010
Mandarin peel, a waste product coming from juice production, was extracted by conventional extraction with 70% acetone. Content of flavonoids in mandarin peel extract (MPE) was determined by HPLC. Hesperidin was the most dominant flavonoid.

The Colorimetric Detection of the Hydroxyl Radical

International Journal of Molecular Sciences, 2023
An aromatic substrate for hydroxylation by hydroxyl radicals (•OH) was investigated. The probe, N,N’-(5-nitro-1,3-phenylene)-bis-glutaramide, and its hydroxylated product do not bind either iron(III) or iron(II), and so they do not interfere with the Fenton reaction.

Preindustrial to present-day changes in tropospheric hydroxyl radical and methane lifetime from the Atmospheric Chemistry and Climate Model Intercomparison Project (ACCMIP) [PDF]

, 2013
We have analysed time-slice simulations from 17 global models, participating in the Atmospheric Chemistry and Climate Model Intercomparison Project (ACCMIP), to explore changes in present-day (2000) hydroxyl radical (OH) concentration and methane (CH4 ...

Mitochondrial toxins potentiate hydroxyl radical production in rat striatum during carbon monoxide poisoning

Journal of Pharmacological Sciences, 2021
Hydroxyl radical (•OH) production in the rat striatum during carbon monoxide (CO) poisoning, which inhibits complex IV, was enhanced synergistically by malonate, a mitochondrial complex II inhibitor, but not N-methyl-4-phenylpyridinium or NaCN, complex I

Proteomic analysis of hydroxyl radical-induced resuscitation of hypoxia-induced dormant mycobacterial cells

International Journal of Mycobacteriology, 2018
Background: The genus Mycobacterium has an ability to persist in hostile environments for years before its reactivation in favorable conditions. The major bottleneck in decades of mycobacterial research is a poor understanding of molecular mechanism ...
