ABSTRACT
This study evaluated the antilipidemic activity of water extracts from leaves
of Desmodium velutinum on albino wistar rats. The phytochemical analysis
of the leaf extract showed the presence of tannins, saponins, alkaloids,
soluble carbohydrates, flavonoids, reducing sugar, steroids, cyanide and
terpenoids. The animals were treated with known drugs (atorvastatin 2ml).
There were significantly reductions in HDL 13.00 1.41 mg/dl LDL 1.20
0.14 mg/dl and triglyceride 39.00 0.14 mg/dl, compared with water extract
of Desmodium velutinum (0.5ml). when administered was found to
significantly reduce lipid plasma which was LDL 1.90 0.00mg/dl,
triglyceride 50.00 0.00mg/dl and increase HDL 25.00 0.00 mg/dl which
is the good cholesterol. The water extract of Desmodium velutinum leaf can
possibly normalize the plasma lipid when compared with the group given
atorvastatin. The phytochemicals analysis showed that the association
between these complexes and compounds and other constituent play an
important role in the biological activity of the leaf. This study suggested that
the water extract of D.velutinum leaf posses hypolipidemic as well as
antilipidemic effect.
