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 ± 307.2 µg/kg) and rutin (73.4 ± 14.0 µg/kg). Apigenin and secoisolariciresinol contents were the highest in yellow lentils (18.5 ± 0.84 µg/kg) and haricot beans (451.9 ± 192.2 µg/kg), respectively. Coumestrol contents of haricot beans (18.5 ± 1.45 µg/kg) and red kidney beans (18.5 ± 1.26 µg/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 ± 0.18 µg/kg) and chickpeas (27.7 ± 1.83 µg/kg). Differences between contents of each sample of the same legume were significant and remarkable, especially for quercetin and secoisolariciresinol.
