Cancer is one of the most prominent human diseases which has stimulated scientific and commercial
interest in the discovery of new anticancer agents from natural sources. The current study investigates the
cytotoxic activity of ethanolic extracts of sixteen Nigerian plants used locally for the treatment of cancer using
the MTT assay on the HeLa cell line.
Sapium ellipticum
leaves showed activity comparable to the reference
compound Cisplatin and greater cytotoxic activity than
Combretum paniculatum
,
Celosia trigyna
,
Drymaria
cordata
,
Cyathula achyranthoides
and
Cyathula prostata
.
Justica extensa
,
Pupalia lappacea
,
Hedranthera
barteri
leaves,
Alternanthera sessilis
,
Ethulia conyzoides
leaves,
Combretum zenkeri
root,
Sapium ellipticum
stembark and
Lannea nigritana
stembark showed very low activity while
Combretum molle
,
Adenanthera
parvoniana
and
Lannea acida
showed no activity. The results justify the use of
Sapium, Combretum, Celosia,
Drymaria and
Cyathula in traditional treatment of cancer.
