six fluorescent compounds were isolated and characterized in rhizomorph of a. mellea and were presented first as: f , f , f , mf , mf and mf . these compounds differed by rf on chromatoplaque, max in uv spectra and ex, em and max in fluorescence spectra. their gc-ms analysis indicated that f has a phenolic moiety and the other five are the benzenic derivatives. f compound was more fluorescent r...

Organotin compound that have at least one Sn-C bond have wide commercial applications as PVC stabilizer, antifouling agent in paint and as agrochemicals. The general formula for organotin compounds is R4SnX4 - n where R is normally alkyl or aryl groups and X=Cl-, OH-, CH3COO- . If n=3, the compound has the highest toxicity, for example Et3SnOAC has LD 50 4mg/Kg ( rats ) and this is the m...
