Objective
To investigate effects of ethanol extract of
Abrus precatorius leaves (EAPL) on egg albumin induced mast cell degranulation in mice and passive cutaneous anaphylaxis in rats.
Methods
In present study ethanol extract of Abrus precatorius leaves (EAPL) at doses of 100, 125, 150 mg/kg i.p were evaluated for preliminary phytochemical screening, acute toxicity studies and egg albumin induced mast cell degranulation in mice and passive cutaneous anaphylaxis in rats.
Results
The results of present investigation showed that the LD50 of EAPL is more than 1?00 mg/kg. EAPL (100-150 mg/kg, i.p.) significantly protect egg albumin induced degranulation of mast cell and inhibit area of leakage of dye in passive cutaneous anaphylaxis. Phytochemical studies observed presence of saponin, alkaloids, flavonoids, and glycosides.
Conclusions
In conclusion EAPL possesses anti asthmatic potential.
