Aims
This work aimed to identify secondary metabolites from aerial parts of Euphorbia species functional for control of toxigenic Fusarium species responsible of cereal grain rots.
Methods and Results
Aerial parts of Euphorbia serpens, Euphorbia schickendantzii and Euphorbia collina were sequentially extracted with hexane, ethyl acetate and methanol. The extracts were tested against strains of...
A 96-well plate micromethod was developed to measure 5-n-alkylresorcinols (5nARs) in cereal grains and food derived products. The 5nARs reacted in alkaline alcoholic medium with Fast Blue RR ½ZnCl 2 salt to yield coloured azo-derivatives. The highest sensitivity for 5nARs was obtained at 490nm with 0.025% ethanolic Fast Blue RR and 5% K 2 CO 3. This reaction showed good linearity...
