Фитохимическое и ботаническое исследование перспективного лекарственного растения Nonea rossica Steven

Abstract

Introduction. Nonea rossica Steven is a widespread in Western Siberia herbaceous plant of the Boraginaceae family. It is used in folk medicine as an antimalarial, antibacterial, analgesic, anti-inflammatory and anticoagulant agent, and in this regard, the plant is promising for study with a view to introducing it into practice as an officinal medicine. Aim. Phytochemical and morpho-anatomical study of aboveground and underground organs of Nonea rossica Steven. Materials and methods. A phytochemical analysis was performed using conventional methods. The anatomical structure of plant organs was reveal using microscopic analysis. Results. The presence and content of the main groups of biologically active substances was established: the content of flavonoids in the aboveground part in terms of rutin was 0.2%; tannins of the condensable group in aboveground parts of plant – 3.8%, in roots – 0.6%; xanthones in terms of mangiferin in roots – 0.01%, in herb – 0.008%; polysaccharides in herb – 4.37%. Microscopic analysis allowed to establish the main microdiagnostic signs of vegetative and reproductive organs of Nonea rossica Steven. Conclusion. The diverse chemical composition of Nonea rossica Steven allows us to conclude that it is promising to study the plant in order to create new medicines based on it. As a result of micromorphological examination of the aboveground and underground organs of Nonea rossica Steven, it was possible to identify diagnostic signs for the identification of raw materials, which will become the basis for the draft of a monograph.
