| Abstract | Annona muricata Linn. also called “Soursop” or “Sharp Sharp” is traditionally used in treatment of cancer. There are many claims that Annona muricata L. can kill cancer cells, since its leaves, seeds and fruits contain active compound called annonaceous acetogenins. This research was aimed to evaluate the antiproliferative and chemopreventive effect of Annona muricata L. leaf extract against Ehrlich ascites carcinoma and benzo[a]pyrene induced lung carcinoma. In Ehrlich ascites carcinoma model, the tumor bearing mice treated with methanol extract of Annona muricata leaves 200 mg/kg and 400 mg/kg once daily orally started 24 h after inoculation significantly reduced the viable cell count. The dose level of 400 mg/kg showed a significant increase in non-viable count with a significant decrease in body weight of animals compared to EAC control animals. The haematological parameters were reverted to more or less normal levels in animals treated with extract 400 mg/kg. In benzo[a]pyrene induced lung cancer model, treatment with extract started 1 week before benzo[a]pyrene induction and continued once daily for 16 weeks, effectively suppressed lung cancer. There was a significant increase in weight gain during experimental period with a significant decrease in relative lung weight and serum cancer marker - carcinoembryonic antigen at the end of experimental period. Gross morphology of lung also appeared near normal to lung of normal animals. Moreover, with reference to lipid peroxidation and antioxidant system, Annona muricata leaf extract decreased the extent of lipid peroxidation with concomitant increase in activities of superoxide dismutase, catalase and reduced glutathione compared to lung cancer bearing untreated animals. It was observed that extract 400 mg/kg showed a significant protection against benzo[a]pyrene induced carcinogenesis. Histological examination of lung tissue too correlated with morphological and biochemical observations. Our data suggest that, the potential anti-proliferative and chemopreventive action of Annona muricata leaves might be due to cytotoxic mechanism against cancer cells in the pathway of apoptosis and inhibition of cell cycle. Furthermore, our in-vitro investigation on extract showed a potent free radical scavenging activity. An additional antioxidant property of Annona muricata leaves might be responsible for chemoprevention by stabilizing all the components of antioxidant defense which were disturbed during benzo[a]pyrene induced oxidative damage. |

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.
