Physical And Chemical Properties, Elemental Composition And Microbiological Purity Of Oil Extract Of Chamomile Flowers In Bitter Almond Oil, Khakim Tukhtaev, Sevara Khazratkulova
CHEMISTRY AND CHEMICAL ENGINEERING
The aim of the study was to obtain an oil extract with the participation of chamomile officinalis (Matrigaria Recutito) grown in the Tashkent region using bitter almond oil (Amygdalus communis L.). Its chromatographic and elemental analyzes have been carried out, its microbiological purity and physicochemical constants have been determined. For extraction, we used bitter almond oil obtained by cold pressing. Extraction of chamomile flowers in bitter almond oil was carried out by maceration in the ratio of raw material: solvent (1:10). Analysis of fatty acids in the fatty extract was carried out chromatographically. The fatty extract was found to contain …

Obtaining Of Bacterial Polysaccharides, Kulonov Abdulaziz, Mirzarakhmetova Dilbar, Turaeva Nigora
CHEMISTRY AND CHEMICAL ENGINEERING
The aim of this work was to develop a technology for obtaining bacterial exopolysaccharides. The problem was solved by using the bacterial strain Halovibrio variabilis UzAS3 as a polysaccharide producer. The optimal parameters of bacterial cultivation have been determined. A technological scheme for obtaining bacterial polysaccharides has been developed, which includes such stages as the cultivation of bacteria, the separation of bacterial biomass from the culture liquid, desalting, precipitation, washing and drying. The obtained results show that bacteria have a high potential for the yield of bacterial exopolysaccharides (7.1-9.5 mg/ml).
