| Abstract | A rapid and sensitive method based on magnetic solid-phase extraction coupled to high-performance liquid chromatography with ultraviolet detection was developed for the simultaneous determination of buprenorphine (BPN) and its major metabolite, norbuprenorphine (N-BPN), in human plasma samples. Poly (para-phenylenediamine)-modified Fe$_{3}$O$_{4}$ nanoparticles (PpPDA/Fe$_{3}$O$_{4}$) were synthesized and used as a magnetic adsorbent for the extraction and preconcentration of BPN and N-BPN in biological samples. The synthesized nanocomposites were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, field emission scanning electron microscopy, transmission electron microscopy, energy-dispersive X-ray spectroscopy and vibrating sample magnetometery. An isocratic separation was achieved on a Nova-Pak C18 reversed-phase column using a mobile phase consisting phosphate buffer (pH 3.4) and acetonitrile (50:50, v/v) at a flow rate of 1.0 mL min$^{−1}$. The detection was conducted at 280 nm. Under the optimum conditions, the calibration curves for BPN and N-BPN were linear in the ranges 3.0–150.0 and 1.0–120.0 ng mL$^{−1}$, respectively. The sensitivity was also high with limit of detection of 0.8 and 0.3 ng mL$^{−1}$ for BPN and N-BPN in plasma, respectively. The method was successfully applied to the extraction and determination of BPN and N-BPN in human plasma samples with an average recovery of 98.10 and 96.41%, respectively. |

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.
