| Abstract | Calli cultures derived from the leaves of Saussurea medusa were selected on the basis of colour into three callus, A, B and C, which suggested different levels of metabolite accumulation. An improved reversed phase high performance liquid chromatographic method provided selective determination of the jaceosidin content of these samples. The jaceosidin concentration in callus B was higher than that of the callus A and C. By using 12-day old culture and 9-day old inoculum, jaceosidin yield of 72.91 mg l$^{−1}$was obtained from cell line B in cell suspension cultures. The influence of some factors affecting jaceosidin formation, i.e. temperature, light, inoculum size, type of media, phytohormones, nitrogen and carbon source etc. were also examined. Light irradiation and combination of 3% (w/v) sucrose with 1% glucose brought about a marked increase of jaceosidin production. The effect of blue light on jaceosidin was markedly superior to other kinds of monochromatic light (red and far-red) or white light. Analysis of growth and jaceosidin content of callus cultures and cell suspension cultures demonstrated that the production of jaceosidin was growth-dependent in both cell solid culture and cell suspension culture. |

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.
