Abstract

Despite several reports on the beneficial effects of buckwheat in prevention of human diseases, little attention has been devoted to the variability of biochemical and physiological traits in different buckwheat genetic resources. The biochemical evaluation of buckwheat genetic resources and the identification of the elite genotypes for plant breeding and exploitation have been studied. Various types of bioactive compounds in different varieties provide basic background information needed for the efficient production of buckwheat food with added values. Results of our research work show that presence of anthocyanins in the vegetative organs of buckwheat can be a reliable genetic marker for screening plants with high content of rutin. We have compared F. esculentum Moench (cultivars Lileya, Bilshovik, Rubra), F. tataricum (ssp. rotundatum Krot. and ssp. tuberculatum Krot.), F. cymosum Meissn, and F. giganteum Krot. The highest rutin content was measured in inflorescences of F. esculentum Rubra. The comparative analysis of total phenolics and phenolic acid composition together with antioxidant activities in inflorescences of F. esculentum, F. tataricum rotundatum and F. esculentum (green-flowers) shown that F. esculentum inflorescences have been characterized by the highest content of salicylic acid (115 mg 100 g-1 DW) and methoxycinnamic acid (74 mg 100 g-1 DW). The highest content among the investigated buckwheat inflorescences of vanillic acid, trans-ferulic acid, chlorogenic, acid and p-anisic acid was found in the F. tataricum. Inflorescences of F. esculentum (green-flowers) have a high content of chlorogenic acid (16 mg 100 g-1 DW), p-anisic acid (872 mg 100 g-1 DW). The highest fagopiryn content was measured in inflorescences of F. esculentum, (green-flowers).
