The study of indicators of authenticity and goodness of flowers of narrow-leaved lavender (<i>Lavandula angustifolia</i> L.)

Abstract

The study is dedicated to the analysis of the cultural and medicinal plant Lavandula angustifolia Mill. from the Lamiaceae Martinov family. The plant is widely used in the food and perfume-cosmetic industries, as well as in traditional medicine for treating various diseases including rheumatism and migraines. The research focuses on the analysis of phenolic compounds and terpenoids, which are the main pharmacologically active components of narrow-leaved lavender. Phenolic compounds include flavonoids, phenolic acids, and coumarins, while terpenoids such as linalool and linalyl acetate are responsible for the aromatic essential oil. The experiment involved studying the quantitative content of flavonoids, chromatographic analysis of secondary metabolites, and microscopic analysis of the structure of narrow-leaved lavender flowers. The obtained data expand the nomenclature of pharmacopoeial herbal raw materials. The quantitative content of flavonoids and the profile of major polyphenolic secondary components have been established. These results can serve as a basis for standardization and quality assessment of narrow-leaved lavender flowers, as well as for further phytochemical and pharmacological research.
