Popis: | An antiplasmodial activity-guided isolation was carried out on the dichloromethane extract of Tithonia diversifolia dried leaves. A total of five germacranolide type sesquiterpene lactones and a new flavonol, 3,6-dihydroxy-2-(4′-hydroxyphenyl)-7-methoxy-4H-chromen-4-one, were isolated. The flavonol reported an IC50 above 6.00 µM against the chloroquine sensitive strain, NF54. The antimalarial activity of the Tithonia diversifolia dichloromethane leaf extract was attributed to orizabin and tagitinin C. |
