| Abstract | Ulmus wallichiana is an endangered and folk medicinal plant used for healing fractures in India. Recently, the secondary metabolites isolated and identified from its bark revealed osteogenic activity. Considering the medicinal properties of its bark and the source for its identified and isolated metabolites, the requirement for production of alternative pathways was crucial. This study aimed to determine its bioactive metabolite using Quadrupole time-of-flight liquid chromatography-mass spectroscopy (Q-TOF LC/MS) in different parts of this plant with seasonal and altitudinal variability pertaining with the development of a protocol for induction of callus cultures and biomass production. Plant samples were collected during December–March, April–July and August–November in the year 2010–2012 from three different altitudinal locations (Nainital, Almora and Bageshwar districts) of Kumaon region, Uttarakhand, India. The results obtained from Q-TOF LC/MS analysis demonstrated the presence of four bioactive metabolites known for osteogenic activity in bark and stem samples round the year. Syntheses of bioactive metabolites in leaf samples were significantly affected by sampling season as well as altitudinal locations respectively. Callus derived from leaf explants was maintained in Murashige and Skoog medium containing (0.25 mg l−1) 2,4-Dichlorophenoxy-acetic acid (2,4-D) + (0.05 mg l−1) Kinetin and (0.25 mg l−1) α-Naphthaleneacetic acid + (0.5 mg l−1) 6-Benzylaminopurine in liquid phase showed optimal conditions for accumulating biomass and synthesis of identified bioactive metabolites. |

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.
