| Abstract | This article reports on the structural characteristics and antioxidant activity of unmodified autohydrolyzed ethanol organosolv lignin (AH EOL) extracted from oil palm fronds (OPF) and modified autohydrolyzed ethanol organosolv lignin via incorporation of p-nitrophenol (AHNP EOL). The isolated lignin were analyzed by FTIR, H and C NMR spectroscopy, 2D NMR; HSQC and HMBC, CHN analysis, molecular weight distribution using GPC analyzer, thermal analysis; TGA and DSC. The chemical modification by utilizing an organic scavenger during delignification process provided smaller lignin fragments and enhanced the solubility of lignin by reducing its hydrophobicity properties. It was revealed that the antioxidant properties increased as compared to the unmodified organosolv lignin. Additionally, the modified lignin has better solubility in water (D =35%>D =25%). |

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.
