Abstract | Curcumin is a natural active constituent with a great variety of beneficial biological and pharmacological activities, is a practically water-insoluble component. The scope of the present work was to prepare a solid dispersion (SD) formulation to enhance the dissolution rate of curcumin. The SD was prepared using curcumin and β-cyclodextrin (CD)/HA via a classical ethanol-based solvent evaporation method. The as-prepared β-CD/HA and SDs were selectively characterised by various analytical techniques including X-ray diffraction, transmission electron microscopy, scanning electron microscopy, specific surface area/pore size analysis, Fourier transform infrared spectroscopy, and high-performance liquid chromatography. According to the dissolution tests, it was confirmed that β-CD/HA–curcumin SD can significantly enhance the dissolution of curcumin. In addition, an increasing trend was seen between the β-CD weight ratio and the dissolution rate of curcumin, and β-CD/HA–curcumin (9:1) SD was shown to be the best formulation among all tested samples with over 90% curcumin dissolved in 180 min. Besides, β-CD/HA–curcumin (9:1) SD exhibited pH and medium-dependent curcumin release behaviours. The antioxidant activity of released curcumin showed no difference to original curcumin. These results clearly demonstrated β-CD/HA can be a promising SD carrier to improve the dissolution of curcumin. |

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.
