| Abstract | A rapid, sensitive and highly selective liquid chromatography/tandem mass spectrometry (LC–MS–MS) using an atmospheric pressure chemical ionization (APCI) method was developed to determine the concentration of trans-resveratrol in rat plasma. Samples were extracted using ethyl acetate after daidzein was added as an internal standard (IS). The main advantages of this method were the high sensitivity (a lower limit of quantification, LLOQ, of 0.1 ng mL−1) and the short analysis time (total run time 3.2 min per sample). Separation was performed on a ZORBAX ODS column with a mobile phase that consisted of acetonitrile/water (48:52, v/v). trans-Resveratrol and IS were detected using a triple-quadrupole mass spectrometer in the selective reaction monitoring (SRM) mode with the parent-to-product quantifier transitions [M–H]− m/z 226.8 → 142.9 and [M–H]− m/z 252.9 → 252.9 for trans-resveratrol and IS, respectively. The method was confirmed to be accurate and precise with a linearity range of 0.1–500 ng mL−1 with r > 0.99. Recoveries for trans-resveratrol and IS were within 90–101%. The accuracy and precision for the assay were determined by calculating the intra- and inter-batch variation for quality control (QC) samples at four concentration levels with a relative standard deviation (RSD) of <15%. This method was successfully applied to determine trans-resveratrol in rat plasma and proved suitable for pharmacokinetic study after intragastric administration of trans-resveratrol in sustained release granules and normal granules, 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.
