Genetic Potential

In our study we examined the variability of the essential oil content and composition of chamomile (Matricaria recutita L.) during three years (2005-2007). Twenty-eight populations of wild origin and 4 registered cultivars (‘Soroksári 40’, ‘Lutea’, ‘Goral’ and ‘Bona’) were evaluated in open field experiments. It could be established that the experimental populations represented different genetic potential for essential oil accumulation and composition. The best populations of wild growing origin from the Somogy-region and four cultivars produced the highest essential oil contents (above 0.6 g/100g) in each year. Additionally, the quality of the characteristic main compound of the oil determining the “chemotype “, according to Schilcher, was found to be stable during the three years period. However, the actual chemosyndroms are significantly influenced by the weather conditions. In the three years’ experiment, the moderately warm and relatively wet year of 2006 produced the highest contents of essential oil and also that of its α-bisabolol component. Although bisabolol oxide A also showed a high variability through the years, its direct connection with weather conditions could not be proved. A moderate variability was established for the proportions of chamazulene, and the lowest one for bisabolol-oxide B. Considerable genotype-weather interaction was supposed, especially for the essential oil content and for the ratio of bisabolol-oxide A.

Plants of the genus Dracocephalum belong to the subfamily Nepetoideae of the family Lamiaceae of the order Lamiales and include about 70 species worldwide. In Uzbekistan grows 16 species of this genus. The purpose of this study was to study the chemical composition of the essential oil and gasoline extract of Dracocephalum diversifolium. To obtain the essential oil and gasoline extract were used the aerial parts of the plant (stems, flowers and leaves). Essential oil was isolated by hydrodistillation method. The gasoline extract was obtained by treating the air-dried aerial part of the plant with extraction gasoline. The composition of the isolated essential oil and gasoline extract was studied by GC-MS. It was revealed that the predominant components of essential oil content of D. diversifolium was sabinene (20.7%), β-pinene (10.6%), DL-limonene (7.5%), trans-valerenil acetate (7.5%), m-cymene (6.2%), 1,8-cineole (5.0%), T-cadinol acetate (4.4%), δ-cadinene (3.9%), caryophyllene (2.4%). Among the volatiles of the gasoline extract of D. diversifolium was dominated 1,8-cineole (17.0%), 3,5,5,9-tetramethyl-2,4a,5,6,9,9a-hexahydro-1H-benzo[a]cycloheptene (11.2%), δ-cadinene (8.7%), myrtenyl acetate (4.3%), β-pinene (3.9%), 4-terpinenyl acetate (3.2%), δ-cadinol (3.1%), δ-elemene (2.8%), eremophila-1(10),8,11-triene (2.8%), sabina ketone (2.5%), m-cymol (2.2%), 10,12-octadecadiynoic acid (2.0%). For the first time, by hydrodistillation method isolated essential oil from the aerial part of D. diversifolium, growing in Uzbekistan, in which 29 compounds were identified by GC-MS analysis. For the first time the chemical composition of the gasoline extract of the aerial part of D. diversifolium was studied by GC-MS. It was identified 28 components. A comparative analysis of the component composition of the essential oil and gasoline extract of D. diversifolium was carried out, in which established the dominant components for each sample.

The article presents results of the study of a comparative analysis of essential oil obtained from fresh and dried leaves of medicinal sage (Salvia officinalis L.), growing in the Botanical Garden of the First Moscow State Medical University named after Sechenov. The studies were carried out using gas chromatography– mass spectrometry. Qualitative and quantitative difference in the component composition of the essential oil obtained from fresh and dried raw materials was determined as a result of the study.
