Liquid chromatographic-mass spectrometric determination of genistin and daidzin in soybean food samples after accelerated solvent extraction with modified content of extraction cell
Original language description
A newly elaborated accelerated solvent extraction (ASE) procedure allowed more accurate (<2%) and precise (<5-8% rel.) HPLC/UV/MS determination of isoflavones in different kinds of food made from soybean (products of ecological agriculture), i.e. soy farina, soy meat granulate, soy meat laminae, soy meat bits, Protmix and EKO-B1. The on-column limits of detection (LOD) for daidzin/genistin were 1.2/1.6 fmol for the signal-to-noise ratio S/N = 3 and 1-3 fmol for daidzem, genistein, formononetin, biochanin A and ononin, respectively. Final concentrations of daidzin in soybean foods fluctuated between 30 and 60 mug/g of dry matter (DM). Significantly higher concentrations of genistin (between 60 and 130 mug/g DM) were found in the soybean foods.
