| Abstract | For the first time simple, rapid, and systematic methods have been established for preparative isolation and purification of coumarin compounds in an important traditional Chinese Medicine, Radix Angelica dahurica, and for simultaneous determination of several of the compounds in the medicine. Bergapten, imperatorin, and cnidilin, three of the biologically active coumarin compounds, were isolated from the chloroform-soluble fraction of the ethanol extract of Radix Angelica dahurica. After further purification by open column ODS chromatography the purified components were simultaneously determined, with two other coumarins (osthole and isoimperatorin), by reversed phase high-performance liquid chromatography (RP-HPLC) on a C18 column, with methanol–water, 66:34 (v/v), as mobile phase at a flow rate of 0.8 mL min−1. The compounds were detected by UV absorption at 310 nm. Calibration plots for all the coumarins had correlation coefficients close to unity. Limits of detection (S/N = 3) were <92 ng mL−1 and limits of quantification (S/N = 10) were <259 ng mL−1. Mean recovery of the coumarins was in the range 96.7–101.9% and the intra-day and inter-day precision, as relative standard deviation, was <2.3 and <2.9%, respectively. This simple, sensitive, and reproducible method can be used for quality control of Radix Angelica dahurica. |

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.
