| Abstract | Based upon the regulations stipulated by the State Food and Drug Administration of China, only the processed, detoxified tubers and roots of Aconitum are allowed to be administered orally, used in clinical decoctions and adopted as raw materials for pharmaceutical manufacturing, so the processing principle of preparation of Radix Aconiti is important for ensuring the Radix Aconiti praeparata quality. A simple approach was described for HPLC-Q-TOF-MS screening and identification of many of the aconitine alkaloids present in unprocessed Radix Aconiti and Radix Aconiti praeparata. To compare their fingerprints, the processing principle of preparation of Radix Aconiti was developed. Twenty-nine compounds and 26 compounds were assigned to aconitine alkaloids and tentatively identified by comparing accurate mass and fragments information with that of the authentic standards or by mass spectrometry analysis and retrieving the reference literature. The nonester alkaloids were almost the same. The diester diterpene alkaloids were decreased, the monoester-diterpene alkaloids were increased and lipo-alkaloids decreased obviously in the processing of the preparation. These transformed components could be regarded as potential chemical markers that can be used to distinguish between raw and processed herbs. |

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.
