Peroxides - Isolation & purification
Research News and Information
Definition of 'Peroxides'A group of compounds that contain a bivalent O-O group, i.e., the oxygen atoms are univalent. They can either be inorganic or organic in nature. Such compounds release atomic (nascent) oxygen readily. Thus they are strong oxidizing agents and fire hazards when in contact with combustible materials, especially under high-temperature conditions. The chief industrial uses of peroxides are as oxidizing agents, bleaching agents, and initiators of polymerization. (From Hawley's Condensed Chemical Dictionary, 11th ed) |

30 Jul 2009 
Six unreported aromatic compounds, 1-6, were isolated, along with the known compounds dehydrocurcuphenol and manoalide, from a sample of Plakortis sp., which was the main component of a Pacific sponge consortium. The new molecules were chemically ... Read more...
Mycangimycin, a polyene peroxide from a mutualist Streptomyces sp.
3 Feb 2009 
A mutualist actinomycete of the southern pine beetle, Dendroctonus frontalis, produces a polyene peroxide with pronounced antifungal activity. Its structure, absolute configuration, and biological activity were determined by spectral analysis, ... Read more...
Larvicidal and nematicidal activities of the leaf essential oil of Croton regelianus.
29 Nov 2008 The chemical composition of the leaf essential oil of Croton regelianus collected from wild plants growing in two different sites at Ceará State (Brazil) was analyzed by GC/MS and GC-FID. Twenty monoterpenoids, representing more than 96% of the ... Read more...
