Essential Oil Chemical Composition of Lavender Varieties Cultivated in an Untraditional Agro-Ecological Region

Abstract

A field experiment has been conducted in the region of Dobrudja with the aim to investigate the essential oil yield and its chemical composition by four lavender varieties: Hemus, Sevtopolis, Yubileyna and Druzhba. The experiment has been arranged according to the Randomized Complete- Block Design in four replications and a plot size of 10 m2. The essential oil yields varied from 90 l ha-1 by the variety Hemus to 131 l ha-1 by the variety Sevtopolis. The major constituents of the essential oil were linalyl acetate (25.5-39.7%) and linalool (27.6- 38.9%). The content of linalyl acetate was the highest by the variety Hemus, as only by this variety the ratio between linalyl acetate and linalool is 1:0.7, which defined the essential oil as high qualitative.

Evaluation and estimation of diuretic activity of the linalyl acetate in the rats

“…In regards to its structure, LA is a racemate that comprises equimolar amounts of both (S)-and (R)-Linalyl acetate. The chemical is additionally represented by the molecular structure C 12 H 20 O 2 with a molecular weight of 196.29 (Georgieva et al, 2022). Diuretics are used for the reduction of blood pressure and edema (Hsieh et al, 2018).…”

Lavender essential oil - properties and uses

“…В България са създадени и одобрени от Държавна сортова комисия 14 сорта лавандула (принадлежащи към вида Lavandula angustifolia Mill.). Те са с много добри показатели, като при някои от сортовете ценната съставка линалилацетат достига до 60% (Georgieva, 2013).…”
