It is well known from literature data that extraction conditions
and characteristics of the sample can affect the efficiency of the
extraction, independently or interactively. The solvent and the temperature are the process parameters that usually have the
greatest impact on the efficiency of extraction of bioactive
compounds from the plant material. In general, alcohol/water
solutions exert a better influence on the extractability of phenolic
compounds in comparison to the mono-component solvents. It is
noted that a solvent system for extraction is selected according to
the purpose of extraction such as preparation or analysis, the
nature of interested components, the physicochemical properties
of the matrix, the availability of reagents and equipment, cost and
safety concerns
