| Abstract | Boehmeria macrophylla is a perennial herb used as folk medicine in Bangladesh for the healing of pathologic conditions like fever, trauma, dermatitis, boils etc. After phytochemical screening of ethanolic extract of B. macrophylla (Urticaceae) leaf (BMET), in vitro antioxidant activity was investigated by free radical (DPPH) scavenging assay. Total tannin, phenolic and flavonoid contents were also estimated. Analgesic, cytotoxic and antibacterial activities were evaluated by ‘acetic acid induced writhing inhibition in mice’, ‘brine shrimp lethality bioassay’ and ‘disk diffusion assay’, respectively. Phytochemical screening indicated the presence of alkaloids, tannins, flavonoids, saponins, steroids and terpenoids. The extract showed scavenging activity with IC$_{50}$ value of 39.76 μg/mL whereas IC$_{50}$ was 6.86 μg/mL for ascorbic acid. The extract also showed the total phenolic, flavonoid and tannin content as 439.48, 356.84 and 395.42 mg QE/100 g of dried plant extract. BMET showed 32.91 % and 54.2 % writhing inhibition in mice at doses 250 and 500 mg/kg, respectively. BMET showed LC$_{50}$ against brine shrimp nauplii at 33.16 μg/mL. The extract also showed antibacterial activity against Vibrio cholerae, Escherichia coli, Staphylococcus epidermidis and Streptococcus ferus. The results suggest that BMET has antioxidant, analgesic, cytotoxic and antibacterial activities. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
