Medicinal use of plants is as old as human history. , seeds, and have been widely used in various remedies since ages. In this study, the effect of extraction method on different bioactivities and phytochemical constituents of , seeds, and were evaluated and compared using single solvent system (50% ethanol). Plant extracts were prepared by percolation-assisted extraction, sonication-assisted extraction, microwave-assisted extraction, and polyphenol extraction. Following phytochemical screening, extracts were screened for antioxidant activity, antihemolytic activity, osmotic tolerance, and osmotic fragility. All plant extracts showed good phytochemical content irrespective of extraction method. However, activities antioxidant assays were dependent on plant as well as on extraction methods. Promising results were observed for antihemolytic activity against hydrogen peroxide-treated erythrocytes. Overall, exhibited the highest bioactivities followed by and seeds.
植物的药用与人类历史一样悠久。自古以来,种子等就已广泛用于各种疗法。在本研究中,使用单一溶剂系统(50%乙醇)评估并比较了提取方法对[植物名称1]、[植物名称2]种子和[植物名称3]不同生物活性及植物化学成分的影响。通过渗滤辅助提取、超声辅助提取、微波辅助提取和多酚提取制备植物提取物。经过植物化学筛选后,对提取物进行抗氧化活性、抗溶血活性、渗透压耐受性和渗透脆性的筛选。无论采用何种提取方法,所有植物提取物均显示出良好的植物化学成分含量。然而,抗氧化测定的活性取决于植物以及提取方法。在针对过氧化氢处理的红细胞的抗溶血活性方面观察到了有前景的结果。总体而言,[植物名称1]表现出最高的生物活性,其次是[植物名称2]和[植物名称3]种子。
