This study, hexane extract of E. prostrata Linn was evaluated for bioactivities. The extract showed its new action as a potential vasorelaxant. Moreover, antioxidative (SOD and DPPH assays) and cytotoxic activities of the extract were also observed. Isolation of the extract provided a stigmasterol including eight fractions of triterpenoids along with long chain hydrocarbons. All the fractions exhibited antimicrobial activity with minimum inhibitory concentration (MIC) range of 64-256 μg/mL. The results imply therapeutic value of the plant species as an alternative medicinal source of potential vasorelaxants. © EuroJournals Publishing, Inc. 2010.Mahidol UniversityAgricultural and Biological SciencesComputer ScienceEarth and Planetary SciencesEngineeringMaterials ScienceMathematicsArticleSCOPUS
