| Abstract | OBJECTIVE: To evaluate the antileishmanial activity of different extracts from three Cuban Pluchea species. METHODS: In in vitro assays the IC(50) was calculated in the promastigotes and amastigotes forms as cytotoxicity in murine macrophages. In leishmaniasis cutanea experiment, mortality, weight loss, lesion size and burden parasite were measured. RESULTS: Extracts evaluated showed inhibitive effect on growing of promastigote form; however, active extracts caused a high toxicity. Ethanol and n-hexane extracts demonstrated specific antileishmanial activity. Ethanol and n-hexane extracts from Pluchea carolinensis (P. carolinensis) caused similar inhibition against amastigote form. The intraperitoneal administration of the ethanol extract of P. carolinensis at 100 mg/kg prevented lesion development compared with control groups. CONCLUSIONS: The antileishmanial experiment suggests that ethanol extracts from P. carolinensis is the most promising. Further studies are still needed to evaluate the potential of this plant as a source of new antileishmanial agents. |

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.
