Bio-activities of the methanol extracts from some species belonging to the family Asteraceae in Lam Dong province

Abstract

The methanol extracts from 8 species belonging to the family Asteraceae in Lam Dong province were evaluated through antibacterial, DPPH radical scavenging and cytotoxic tests. The MeOH extracts from Ageratum conyzoides L. (whole plant), Bidens pilosa L. (whole plant) and Chromolaena odorata (L.) R. M. King & H. Rob. (aerial parts) showed the highest capacities in Esherichia coli and Staphylococus aureus tests. In the DPPH radical scavenging test, the MeOH extracts from Sonchus oleraceus L. (whole plant), Pluchea indica (L.) Less (aerial parts) and Xanthium strumarium L. (fruits) were the most active. The MeOH extracts from Elephantopus mollis H. B. K. (whole plant), Chromolaena odorata (L.) R. M. King & H. Rob. (aerial parts) and Xanthium strumarium L. (fruits) showed cytotoxic activities.
