Description
Summary:•Sour cherry (Prunus cerasus L.) cultivars grown in Hungary were studied.•Screening and quantitation of genistein compounds were carried out.•Genistein and genistin were found in substantial amounts in 4 cultivars. The isoflavone genistein on the contrary to its well-established health-beneficial effects is not a major component of the Western diet, since soy consumption, considered as the main dietary source of genistein, in these populations is low. Genistein compounds in twelve commercial sour cherry (Prunus cerasus L.) cultivars grown in Hungary were studied. High performance liquid chromatography coupled to electrospray ionisation quadrupole/time-of-flight mass spectrometry (HPLC-ESI-qToF-MS) was used for screening and confirmatory analyses. Genistin and genistein were found in ‘Pipacs1’, ‘Kántorjánosi’, ‘Debreceni bőtermő’ and ‘Éva’, which are native cultivars to Hungary. Genistein content of the latter three were in the range of 0.4–0.6, while in ‘Pipacs1’ in total 4.4mg genistein compounds were measured expressed as aglycone equivalents per 100g of fresh fruit flesh. These cultivars may play important role as complementary genistein sources in the Western diet. Especially ‘Pipacs 1’, may be best utilised in functional food products.
