A novel method for measuring the antioxidant activity using N, N-dimethyl-p-phenylenediamine (DMPD) was developed. The radical cation of this compound gives a stable colored solution and a linear… Expand
Occurrence of fusaproliferin, fumonisin B1, and beauvericin in maize from Italy
The occurrence of fusaproliferin (FP) was investigated in 22 samples of preharvest maize ears Fusarium rot, collected in 1994 in Italy. The most frequently recovered Fusarium species were Fusarium… Expand

Fusarium subglutinans is an important pathogen of maize and other commodities worldwide. We examined MRC-115 and 71 other F. subglutinans strains from various geographic areas for their ability to… Expand
Natural occurrence of beauvericin in preharvest Fusarium subglutinans infected corn ears in Poland
Fourteen samples of preharvest infected corn ears, collected in 1990-1991 from different Polish cornfields, were found to be highly infected by fusarium subglutinans. This species was recently shown… Expand
Beauvericin production by Fusarium subglutinans from different geographical areas
The capability of sixty-five F. subglutinans, mostly from maize, isolates to produce beauvericin (BEA) was evaluated. Strains from various geographic areas were cultured on autoclaved corn kernels… Expand
Teratogenic Effects of Fusaproliferin on Chicken Embryos
Fusaproliferin (FP) is a sesterterpene mycotoxin produced by some species of Fusarium, common contaminants of maize. Toxicity assays on Artemia salina L. brine shrimp larvae using FP and its… Expand
Identification of a β-lactoglobulin lactosylation site
Thermal treatment of milk leads to non-enzymatic glycosylation of proteins through Maillard reaction. Free NH2 groups of basic amino acids react with the reducing carbonyl group of lactose forming… Expand
Isolation and characterization of fusaproliferin, a new toxic metabolite from Fusarium proliferatum.
A new toxic sesterterpene, named fusaproliferin, was purified from corn kernel cultures (120 mg/kg dry culture) of a strain of Fusarium proliferatum isolated from corn ear rot in northern Italy. The… Expand

Six selected samples of preharvest maize ear rot, from different localities in Sardinia, Italy, were examined for causal Fusarium species and associated mycotoxins. All samples were almost… Expand
1H and 13c nmr analysis of lycorine and α-dihydrolycorine
Abstract -The 1 H and 13 C NMR spectra of lycorine and its α-dihydro derivative have been studied. The employment of nuclear magnetic double resonance, nuclear Overhauser effect and acetylated… Expand
