Background: Eclipta alba Hassk. (Family: Compositae) contains coumestans
useful in liver problems. The present work is aimed to develop a new formulation of
plant-derived coumestans in combination with the soya-phosphatidylcholine (PC) and it
is expected to improve the absorption of coumestans. The study also examines the protective
effect of coumestans-phosphatidylcholine complex (C-PC) on carbon tetrachloride
(CCl4) induced acute liver injury in rats.
Method: Coumestans (C) were characterized in the ethyl acetate fraction of methanolic
extract (EFME). The C-PC was characterized by DSC and FTIR spectroscopy. In vitro
drug release from EFME and C-PC through egg-membrane was measured using a UVVisible
spectrophotometer. The hepatoprotective activity of C-PC (equivalent to 5.35 and
10.7 mg/kg body weight of EFME), ME 250 mg/kg and EFME 5.35 mg/kg was analyzed
by assessing the level of various enzymes.
Conclusion: C-PC significantly (P<0.001) provided better protection to the liver by normalizing
the levels of enzymes SGPT, SGOT, ALP and total bilirubin when compared to
CCl4 group. The histopathological study showed that C-PC showed improvement in rat’s
liver as compared to ME and EFME at similar doses as they showed regeneration of hepatocytes,
central vein, intact cytoplasm and nucleus.
