Abstrakt: Various parts of Sesbania grandiflorahave been used in the Indian system of medicine, in particular, the leaves of S. grandifloraare used in Ayurveda for the treatment of epileptic fits. In the present study we have evaluated the anticonvulsive activity of S. grandifloraleaves using a variety of animal models of convulsions. Bioassay guided separation was also carried out to identify the fraction possessing anticonvulsant activity. The benzene:ethyl acetate fraction (BE) of the acetone soluble part of a petroleum ether extract significantly delayed the onset of convulsions in pentylenetetrazol (PTZ) and strychnine (STR)‐ induced seizures in mice and reduced the duration of tonic hindleg extension in the maximum electroconvulsive shock (MES) induced seizures in mice. The BE contained a triterpene as a major component. In addition, the BE also inhibited electrically induced kindled seizures in mice and lithium‐pilocarpine‐induced status epilepticus in rats. It prolonged the duration of sleep induced by pentobarbital and antagonized the effect of D‐amphetamine. Mice treated with BE preferred to remain in the open arm of the elevated plus maze indicating anxiolytic activity. The BE raised the brain contents of gamma‐aminobutyric acid and serotonin. Thus the triterpene containing fraction of S. grandifloraexhibits a wide spectrum of anticonvulsant profile and anxiolytic activity. Copyright © 2002 John Wiley & Sons, Ltd.
