The different solvents used were methanol, ethanol, acetone at three different concentrations (50%, 80%, and 100%) and 100% distilled water. The crude extracts were filtered through Whatman No. 1 filter paper, and the residues were washed with the
corresponding solvents to maintain 50 ml final volume of the filtrate. In the second part of this work, the effects of different extraction techniques were studied.
