Abstract

Widely consumed legumes including chickpeas, red kidney beans, haricot beans, yellow lentils, red lentils and green lentils were analysed to determine the content of non-isoflavone phytoestrogenic compounds such as quercetin, rutin, apigenin, coumestrol and lignan (matairesinol and secoisolariciresinol). Methanolic extracts obtained by ultrasound-assisted extraction were analysed by the triple quadrupole LC-MS/MS. Red kidney beans were the best source of quercetin (603.2 +/- A 307.2 mu g/kg) and rutin (73.4 +/- A 14.0 mu g/kg). Apigenin and secoisolariciresinol contents were the highest in yellow lentils (18.5 +/- A 0.84 mu g/kg) and haricot beans (451.9 +/- A 192.2 mu g/kg), respectively. Coumestrol contents of haricot beans (18.5 +/- A 1.45 mu g/kg) and red kidney beans (18.5 +/- A 1.26 mu g/kg) were equal to each other, and these were determined as the highest coumestrol content values. The best sources of matairesinol occurred in green lentils (28.2 +/- A 0.18 mu g/kg) and chickpeas (27.7 +/- A 1.83 mu g/kg). Differences between contents of each sample of the same legume were significant and remarkable, especially for quercetin and secoisolariciresinol.
