the extracts were applied to 2 species of weeds, a broadleaf (Eclipta prostrata L.) and a narrowleaf (Chloris barbata Sw.), and 3 crop species (Oryza sativa L., Lactuca sativa L. and Brassica alboglabra L.H. Bailey) on filter paper. The results demonstrated that yields of oil, hexane, DCM, EtOAc and EtOH extracts were 0.25%, 1.86%, 8.14%, 11.21% and 9.57% respectively.
