The creation of promising varieties of medicinal plants with useful properties is an actual direction. The acquisition of new highly productive varieties of medicinal plants and their introduction into the culture are successfully implemented in the Nikitsky Botanical Garden, R. Krym. The purpose of this work was to determine the specific features of the essential oil composition of the highly productive varieties Monarda fistulosa L. to determine the prospects of its use in pharmacy and further standardization of raw materials. Essential oil from the aboveground part of Monarda fistulosa L. was obtained by hydrodistillation using the Ginsberg instrument, its content in the raw material reached 2.38% in terms of absolutely dry raw materials. The component composition of essential oil from the aboveground part of the Monarda fistulosa L. was studied by chromatography-mass spectrometry. The presence of 41 components was revealed, 38 of them were identified, the main group being monoterpenes and their derivatives. The highest content of p-cymene, thymol, thymoquinone, thymohydroquinone, carvacrol, γ-terpinene was found in the sample of essential oil. Evaluation of the data of chromatography-mass spectrometry confirms the prospects of using essential oil and Monarda fistulosa L. grass of the assayed variety in pharmaceutical and medical practice as an antimicrobial, anti-inflammatory, antifungal and immunostimulating agent.
The article presents data on the content and component composition of essential oil in the aerial mass of a valuable essential oil crop - Shrub Perilla (Perilla frutescens var. nankinensis (Lour.) Britton), which grows in anthropogenic and natural phytocenoses in the Republic of Abkhazia and it is grown in the Nikitsky Botanical Gardens (the Southern Coast of the Crimea). It was revealed that in the aerial mass of the railing contains from 0.24 to 0.68% of essential oil. The prevalence of perillacetone essential oil (with a relative mass fraction of 39.09-47.79%) and isoegomaketone (40.65-52.40%) in the component composition allows us to attribute the studied samples to isoegomaketone-perillaketone and perilloketone- isoegomaketone chemotypes. Egomaketone (as a precursor in the biosynthesis of perillaketone and isegomaketone), f-karyofellen and a-farnesene are present in small amounts. The results obtained characterize Perilla frutescens var. nankinensis, growing on the territory of the Republic of Abkhazia, as a source of valuable pharmacological essential oils.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
