Herbicidal activity of constituents isolated from Solanum elaeagnifolium (Solanaceae)
The bioactivity of chemical extracts from silverleaf nightshade <em>Solanum elaeagnifolium</em> Cav. seeds and leaves were tested for herbicidal activities, through water and ethanol extracts, against <em>Portulaca oleracea</em> L., <em>Corchorus olitorius </em>L<em>.</em>, <em>Convolvulus arvensis </em>L.and <em>Echinochloa crus-galli</em> (L.) found in most <em>Zea mays </em>L.fields. Characterization of the isolated constituents from ethanol extract was conducted by various spectroscopic techniques. Purification of chloroform (100%) column fraction carried out by TLC plate using developing system; chloroform: ethanol: acetic acid (92:4:4) and hexane: chloroform: ethyl acetate (16:16:1) resulted chlorogenic acid, kaempferol and mangiferin. The second active column fraction eluted by chloroform: ethyl acetate was purified on TLC by chloroform: methanol: water (13:7:1) and butanol:water:formic acid (4:5:1) resulted in (coumaroyl glucoside, coumaroyl quince acid) and (kaempferol β-D-(6”-O-cis-cinnamoyl glucoside), dicaffeoyl quinic acids) respectively. The most active isolated component from<em>S. elaeagnifolium </em>seeds was chlorogenic acid which decreased <em>P.oleracea </em>total biomass fresh weight by (86.5%) followed by kaempferol β-D-(6”-O-cis-cinnamoyl glucoside) (84.4%), while a moderate effect was achieved from coumaroyl glucoside (79.37%), mangiferin (76.98), kaempferol (72.48%) and coumaroyl quince acid (66.47%); finally the lowest activity (63.6%) was achieved by dicaffeoyl quinic acids compared with the controls. Thus, the herbicidal activity of these constituents suggests their potential for development as natural herbicides.
