| Abstract | In vitro antibacterial activities of acetone, ethanol, methanol and water extracts of leaves and bark of Croton roxburghii L. studied against ten human pathogenic bacterial strains showed significantly higher activity in acetone extract and least activity in case of aqueous. Minimal inhibitory concentration (MIC) values of all extracts ranged between 0.62 and 10 mg/ml, while minimal bactericidal concentration (MBC) values ranged from 1.25 to values greater than 10 mg/ml. The antioxidant assays viz. DPPH, hydrogen peroxide scavenging, iron reducing and iron chelating assays along with total phenol and ascorbic acid content were carried out with aqueous extracts of leaves and bark. While the total phenol contents in leaves and bark extracts were 0.766 ± 0.014 and 0.735 ± 0.028% respectively their ascorbic acid contents were found to be 0.252 ± 0.019 and 0.431 ± 0.013% respectively. DPPH activities in both (leaves and bark) extracts increased with the increase in concentrations. Iron chelating capacity of leaves extract is significantly higher than that of the bark. Leaves extract showed an increase in percentage of scavenging property with the increase in concentrations. Plant extracts showed low amount of iron reducing property at all concentrations. Hydrogen peroxide scavenging properties of bark was low than that of the leaves. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
