Optimization of the extractions process of biological active substances from eucalyptus leaves: choice solvents
The Study of hydrocinamic acids, flavonoids, phenolic substances and chlorophyll extraction from Eucalyptus viminalis leaves has been carried out. For extraction of BAS solvents with different dielectric constants have been used. It was installed, that the contents of main BAS in ethylacetate extract were comparable with their contents in primary alcohol extract, from which hereinafter got the thick extract chlorophyllipt. By the way of the studies of chemical composition and antibacterial activities the possibility of the making the modified extract from Eucalyptus leaves, similar chlorophyllipt, without use the alcohol, by means of ethylacetate extractions were proved.
