The analysis of chemical composition of several valuable medicinal and edible plants volatile fraction growing and cultivating in armenian flora by gc-ms method

The analysis of volatile oils` chemical composition by modern chromatographic methods is of great importance nowadays. The chemical composition of the same plants` volatile oil may be changed depending on climatic and cultivating conditions. The chemical composition of a range of plants` volatile oils (such as Smoke tree, Bulbous-rooted chervil, Oregano ordinary, Valeriana cardiola, Germander) studied by GC-MS method, proves, that by chemical composition volatile oils of plants growing in Armenian flora differ from the ones growing in other countries. Besides the chemical composition of the same plants` volatile oils growing in the same flora (Armenian floral also differ depending on cultivating conditions wild, hydroponic, soil culture).
