摘要

Medicinal plants have been known to treat simple to life-threatening diseases in different co<span><span style="font-family:Verdana;">mmunities of Nepal for many years. This study aims to analyze the phytochemicals as plant secondary metabolites, evaluate the antioxidant and antibacterial activities of </span><i><span style="font-family:Verdana;">Rubus</span></i><span> <i><span style="font-family:Verdana;">ellipticus</span></i><span style="font-family:Verdana;">, </span><i><span style="font-family:Verdana;">Ziziphus</span></i> <i><span style="font-family:Verdana;">mauritiana</span></i><span style="font-family:Verdana;">, </span><i><span style="font-family:Verdana;">Pyrus</span></i> <i><span style="font-family:Verdana;">pashia</span></i><span style="font-family:Verdana;">,</span></span><span style="font-family:Verdana;"> and </span><i><span style="font-family:Verdana;">Drynaria</span></i><span style="font-family:Verdana;"> <i>coronans</i></span><span style="font-family:Verdana;"> extracts that are commonly being used as traditional medicine. Phytochemical analysis was performed to investigate the plant’s secondary metabolites such as polyphenols, alkaloids, flavonoids, terpenoids, reducing sugar, glycosides, tannins, carotene, phytosterols, coumarins, saponins, and anthracenes. The methanol extrac</span></span><span style="font-family:Verdana;">ts of the plants were used to evaluate the </span><i><span style="font-family:Verdana;">in vitro</span></i><span> </span><span style="font-family:Verdana;">antioxidant activity by using 2,2-Diphenyl-1-picrylhydrazyl (DPPH) radical and the antibacterial activity against </span><i><span style="font-family:Verdana;">Staphylococcus</span></i> <i><span style="font-family:Verdana;">aureus</span></i><span style="font-family:Verdana;"> (ATCC 25923), </span><i><span style="font-family:Verdana;">Klebsiella</span></i><span style="font-family:Verdana;"> <i>pneumoniae</i></span> <span style="font-family:Verdana;">(ATCC 700603),</span> <i><span style="font-family:Verdana;">Escherichia<
