Abstract
Averrhoa bilimbi Linn. fruit and its extracts were screened for antihypercholesterolemic activity
using Triton-induced hypercholesterolemia in rats as a model. The fruit and its water
extract, but not alcohol and hexane extracts, showed remarkable antihypercholesterolemic
activity. An active fraction, which showed activity at a low dose of 0.8 mg/kg, was
purified from the water extract. An active component was isolated from the active
fraction, which showed optimum activity at a dose of 0.3 mg/kg. The efficacy of the
fruit was tested in chronic high-fat diet fed hyperlipidemic rats. The fruit (125 mg/kg)
as well as its water extract (50 mg/kg) were found to be effective in lowering lipids
in the high-fat diet fed rats. The fruit was subjected to preliminary general toxicity
evaluation in mice. Oral administration of the fruit homogenate daily for 15 days
did not result in any toxic symptoms up to a dose of 1 g/kg studied. Thus, this fruit
can be used as a dietary ingredient to prevent as well as treat hyperlipidemia.
