| Abstract | Bamboo leaves are considered as an important source of bioactive molecules. In this work, leaves from young bamboo (Phyllostachys pubescens Mazel) aged 3 months were subjected to aqueous extraction and 2% NaOH solution extraction followed by precipitation in ethanol-water medium with different ethanol concentrations. The dissolved hemicellulosic polysaccharides presented a total recovery of 67.83% based on the total hemicellulose content in bamboo leaves. Chemical analysis of the fractions was performed by sugar composition analysis, Fourier-transform infrared spectrometry, and 1D nuclear magnetic resonance imaging. The results revealed that all polysaccharide fractions contained xylose, arabinose, glucose, galactose, ribose, and uronic acid. The polysaccharides from young bamboo leaves mainly consisted of arabinoxylans, arabinogalactans, and non-cellulosic ß-D-glucans having (1â3)- and (1â4)-glucosidic linkages. The content of these polysaccharides was found to vary among the fractions depending on the separation method. Finally, the thermal behavior was also discussed. |

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.
