Medicago sativa L. (lucerne or alfalfa) is a species which is generally regarded as a cheap source of valuable protein not only for animal fodder but also for nourishment provided in the poorest and developing countries. Moreover, this plant has a long tradition of use in folk medicine. Numerous studies indicate that besides protein, M. sativa synthesizes a variety of secondary metabolites. Among secondary metabolite classes produced by alfalfa, the saponins and flavonoids are of most interest and well characterized. In the current review, we have summarized their chemical structure and method of identification. The potential of alfalfa extracts in medicine and pharmacology has been highlighted. Furthermore, new ways of utilizing flavonoids as well as saponins in agriculture and horticulture are discussed. Collected data can be the starting point and inspiration for scientists of various specialties for future research on this plant. This review draws attention to the necessity of developing modern analytical tools for identification and quantification of individual M. sativa phytochemicals.
