| Abstract | A high-performance liquid chromatographic method with ultraviolet detection has been developed for the analysis of the polypeptide antibiotic zinc bacitracin in adulterated animal feed. Firstly, the process for extraction of the antibiotic from the feed was optimized. This process involved extraction from the feed at pH 2, centrifugation, liquid-liquid extraction, then solidphase extraction. The extract obtained was then dissolved in the mobile phase and injected into the chromatograph. The best analytical results were obtained by use of a C18 column with a mobile phase comprising a 50:50 (%,v/v) mixture of 0.3m phosphate buffer, pH 3, containing 20mm sodium dodecyl sulfate (SDS) and 19:1 (v/v) acetonitrile-methanol. The analytical signal (peak area) was monitored at 254 nm. The calibration function was estimated between 200 and 1000 mg L−1. The proposed method was applied to the analysis of zinc bacitracin present in different fortified animal feed products at levels between 5 and 200 mg kg−1. Recovery rates were between 66 and 85% and the relative standard deviation was below 7%. |

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.
