| Abstract | Eight antibiotics, chlortetracycline, demeclocycline, doxycycline, methacycline, minocycline, oxytetracycline, tetracycline and rolitetracycline, were separated and quantified in Spanish honey extracts of different floral origin using a commercial RP-C18 HPLC column and two different on-line detectors (diode array and electrospray time-of-flight mass spectrometry (ESI-TOF-MS) systems). Operating a linear gradient at a flow of 2 ml min(-1) the HPLC separation of the eight antibiotics was obtained within 10 min with good peak symmetry and an acceptable resolution (2.1) for the critical band pair rolitetracycline and oxytetracycline. Values of the numbers of theoretical plates (N) were comprised between 2328 and 19448 while the limits of detection in honey were within 0.02-1.03 microg kg(-1) in the case of UV detection and 0.05-0.76 microg kg(-1) for ESI-TOF-MS detection (operating in negative mode). A recovery study was carried out by preparing some quality control samples at four levels of concentration (10, 25, 50 and 100 microg kg(-1)) and percentages between 72% and 98% were attained. |

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.
