Garden savory (Satureja hortensis L.) is an ethereal-oil annual plant belonging to the Lamiaceae family. This plant is cultured in many countries and is used as spicy condiment and as a prophylaxis against various diseases [1 – 3]. Garden savory also occurs in Georgia, where it is readily reproduced (sometimes forming pure scrubs) and cultivated for food(More)
The antioxidant activity of extracts obtained from different parts of Georgian flora species Hamamelis virginiana L., Astragalus caucasicus Pall., Astragalus microcephalus Willd., Vitis vinifera L., Rhododendron ponticum L., Rhododendron Ungernii Trautv., Ginkgo biloba L., Salvia officinalis L., Querqus iberica Stev., Maclura aurantiaca Nutt., Cotinus(More)
The North-American bush Hamamelis virghliana L. (Hamamelidaceae) is successfully cultivated in the moist subtropical Adzhariya region of Georgia. The leaves and preparations of this plant are included in pharmacopeia of many countries and are widely used as a vascular circulation regulator, anti-inflammatory, antihemorrhagic, astringent, and cosmetic(More)
A chemical investigation of plant Satureja hortensis L. - garden savory (GS) has been carried out. It is established that the GS is rich in phenolic compounds. Flavonoids apigenin, luteolin, cinaroside, luteolin-glucuronide, luteolin-rutinoside, isoroifolin and phenylcarbonic acids - chlorogenic acid and rosmarinic acid were isolated from the leaves of the(More)
A petroleum ether extract of the flower heads of the plant Leuoanthemum vu~gare Lam. (family Composltae), which grows widely in the territory of the Georgian SSR, was chromatographed on a column of alumina. The material isolated by elutlon with petroleum ether-benzene (I:i)was rechromatographed on a column of type KSK silica gel, and the substance isolated(More)
The recombination kinetics of a series of flavonoids with stable DPPH radicals are studied. Flavonols are the most reactive. Polarization of the carbonyl in flavones reduces the reactivity. Substitution on C-7 and the B ring has practically no effect on the reactivity. Glycosylation of C-3 reduces the reactivity if the sugar can form two intramolecular(More)
In continuation of the study of flowers of Leucanthemum vulgare Lam. (Compositae) [1-6] collected in the vicinity of Tbilisi (Georgia), we studied the chemical composition of its essential oil (EO). The EO makes up 0.4-0.5% of the air-dried mass and was obtained by steam distillation as a thin light-yellow oily liquid with a specific fragrance. It darkens(More)
Essential oil (1.1%) is isolated fromSalvia officinaliscultivated in Georgia. Its properties are: ρ 20 0.921, n D 20 1.463, [α] D 20 +24.91 , acid number 2.8, ketone content 65.4% (oxime method). GLC showed the presence of 11 terpenes, among which α -thujone (31.56%), β-thujone (17.55), camphor (16.48), and 1,8-cineol (17.53) are present in the highest(More)
The aim of the work was the investigation of pharmacological activity of unique dihydroflavonol glycoside, micranthoside, extracted from the leaves Eupatorium micranthum Less. introduced into Georgia. Mature human T-cell leukemia cell lines (Jurkat) were analyzed in the study under the modeled oxidative stress. For modelling of oxidative stress 30% hydrogen(More)
