A multiresidue method for the determination of organofluorine pesticides in fish tissue samples was developed and optimized. This method is based on a cleanup step of the extracted samples with acetonitrile, and carried out by solid phase extraction (SPE) with aminopropyl (NH2) cartridge, before the identification and quantification of the residues by liquid chromatography triple quadrupole tandem...
The bound phenolic compounds in rice bran were released and extracted with ethyl acetate based on alkaline digestion. An investigation of the chemical constituents of EtOAc extract has led to the isolation of a new compound, para-hydroxy methyl benzoate glucoside (8), together with nine known compounds, cycloeucalenol cis-ferulate (1), cycloeucalenol trans-ferulate (2), trans-ferulic acid (3), trans-ferulic...
