| Abstract | An application of comprehensive two-dimensional gas chromatography-time-of-flight mass spectrometry (GC x GC-ToF MS) use for the analysis of trichothecene mycotoxins is described. Trichothecenes belonging to group A (scirpentriol, HT-2, T-2, 15-monoacetoxyscirpenol (15-MAS), 4,15-diacetylscirpenol (DAS), triacetoxyscirpenol (TAS)) and those belonging to group B (deoxynivalenol (DON), 3-acetyldeoxynivalenol, fusarenone-X, nivalenol) were analyzed and quantified as trifluoroacetic acid anhydride (TFAA) and trimethylsilyl (TMS) derivatives, respectively. The application has been developed for the determination of trichothecenes in wheat grain, after extraction, without any cleanup step. The separation of trichothecenes from matrix constituents was possible due to the vast peak capacity of comprehensive two-dimensional gas chromatography. Despite the presence of uncleaned matrix constituents signal-to-noise ratios for 25 pg of injected trichothecenes ranged from 11:1 to 78:1. Identification of compounds was based on their full spectra. The linearity in a range of 25-2,500 pg was generally 0.999 except for 3-acetyldeoxynivalenol deoxynivalenol and fusarenone-X. RSD for peak areas was <9% for all analyzed toxins. |

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.
