| Abstract | ETHNOPHARMACOLOGICAL IMPORTANCE: Cecropia obtusifolia Bertol (Cecropiaceae) is a plant extensively used for the empirical treatment of type 2 diabetes in México. Although some of its hypoglycemic principles have been described, their mechanisms of action remain unclear. AIM OF THE STUDY: To investigate the anti-diabetic mechanisms of Cecropia obtusifolia aqueous extract (CAE) and its active compound chlorogenic acid (CGA). MATERIALS AND METHODS: Non-toxic concentrations of CAE and CGA were assayed on the adipogenesis and 2-NBDglucose uptake in 3T3-F442A murine adipocytes. RESULTS: Added to adipogenic medium, CAE 70 microg/ml induced a modest increment (20%) in 3T3 adipogenesis whereas CGA did not affect adipogenesis at any of the tested concentrations (0.1-100 microM). Both preparations stimulated 2-NBDG uptake in adipocytes by 51% (CAE) and 176% (CGA) in the absence of insulin, and by 174% (CAE) and 404% (CGA) in the presence of the hormone. CAE and CGA also stimulated the 2-NBDG uptake in insulin-resistant 3T3 adipocytes by 35% and 141%, respectively, compared with the incorporation shown by insulin-sensitive adipocytes stimulated by the hormone. The potency of CGA to stimulate 2-NBDG uptake was comparable to the anti-diabetic drug rosiglitazone. CONCLUSION: Cecropia obtusifolia and CGA exert their anti-diabetic effects stimulating glucose uptake in both insulin-sensitive and insulin-resistant adipocytes without appreciable pro-adipogenic effects. |

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.
