Isoegomaketone chemotype of Perilla frutescens var. nankinensis (Lour.) Britton

Abstract

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.
