COMPONENT COMPOSITION OF THE EXTRACTS AND ESSENTIAL OILS FROM THE ALHAGI PERSARUM, GROWING IN UZBEKISTAN AND THEIR ANTIMICROBIAL ACTIVITY

The volatile compounds of hexane and benzene extracts were studied by GC-MS analysis, as well as were investigated the composition of essential oils obtained by steam and hydrodistillation from the aerial part of Alhagi persarum Boiss. & Buhse, collected during the flowering period in the Fergana region of the Republic of Uzbekistan. As a result of the studies, 44 components were found in the hexane and benzene extracts, among them the neophytadiene (44.0%), hexahydrofarnesyl acetone (20.5%), phytol (17.1%), dihydroactinidiolide (2.0%), a-thujone (32.1%) and b-thujone (9.8%), camphor (30.5%) are dominated. In the composition of essential oils isolated by steam and hydrodistillation methods, were identified 69 and 56 compounds, respectively. The dominating components are eucalyptol (4.7% and 2.9%), a-thujone (44.0% and 35.3%) and b-thujone (17.1% and 14.3%), camphor (12.7% and 28.2%). In vitro screening for antibacterial and antifungal activity of extracts were carried out, as well as EО from Alhagi persarum. Among the samples studied, EO, obtained by steamdistillation, possesses the highest antimicrobial activity against Bacillus subtilis (15 mm), Staphylococcus aureus (13 mm), Escherichia coli (11 mm) and Candida albicans (8 mm).
