چکیده
2.1.1 Aqueous extracts preparation The dried form of plant was mixed with sterile distilled water in a ration of 1:20 (100 g in 1 L solvent), and was stirred and heated for about 4 hours. After cooling, the extract was filtered by using Whatman No.1 filter paper. The filtrate was collected and frozen in ice cube container. The frozen ice cube was freeze-dried (i.e. lyophilisation) to obtain concentrated, aqueous extracts in powder form.
