| Abstract | Cathodic adsorptive stripping voltammetry (CASV) was applied for the determination of rutin in pharmaceuticals, human urine, and blood serum. An electrochemical stripping procedure for trace measurements of rutin was developed based on the adsorption of the Cu2+-rutin complex on a hanging mercury drop electrode and applied to the quantification of the drug. Cyclic voltammetry was used to characterize the interfacial and redox behavior of the adsorbed Cu2+-rutin complex. Experimental and instrumental parameters for quantitative determination were optimized, and a detection limit of 4.9 × 10−9 mol · L−1 in presence of Cu2+-ions for quantification of rutin under optimum conditions was derived. The sharp peak of the adsorbed Cu2+-rutin complex associated with an effective interfacial accumulation of this compound facilitates the determination of rutin in biological fluids with good recoveries. The degree of interference from potentially present metal ions and organic compounds on the CASV signal for Cu2+-rutin complex was evaluated. |

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.
