SUMMARY
Sainfoin (Onobrychis) is a genus of the legume family that is notable for its high species diversity. The plant O. bobrovii is one of the most widespread species of the genus sainfoin in Azerbaijan, exhibiting a wide range and substantial raw material base. A chromatographic and identititative analysis of flavonoids obtained from the grass of this plant was conducted. The spectrophotometric method also revealed that the grass of O. bobrovii contains 4.34% flavonoids. As with other types of sainfoin, O. bobrovii represents a promising source for the production of individual flavonoids, and further studies are currently underway to develop new dosage forms based on isolated flavonoids.
Keywords: Onobrychis bobrovii Grossh., flavonoids, qualitative reactions, chromatographic
