Anticonvulsant Effect of Berberis integerrima L. Root Extracts in Mice
Hossein Hosseinzadeh,Mohammad Ramezani,Hojjat Shafaei,Elahe Taghiabadi 사단법인약침학회 2013 Journal of Acupuncture & Meridian Studies Vol.6 No.1
Berberis integerrima is a member of Berberidaceae family. Berberine is one of the main constituents of this plant, having neuroprotective effect on central nervous system diseases. In this study, the anticonvulsant activity of methanolic extract, and hydromethanolic fraction, and chloroform fraction of B integerrima was assessed. The anticonvulsant effect of B integerrima was investigated using both pentylenetetrazole (PTZ) and maximal electroshock (MES)-induced seizure models. The LD50 value of the methanolic extract was 302.676 mg/kg. In the PTZ test, methanolic extract (140 and 200 mg/kg,i.p., p < 0.01), hydromethanolic fraction (200 mg/kg, p < 0.01), and chloroform fraction (200 mg/kg, p < 0.01) increased the onset time of hind limb tonic extensions (HLTEs). The protective effect against mortality (convulsion survivors/animals tested) was 2/8 in methanolic extract, and 3/8 in hydromethanolic fraction at a dose of 200 mg/kg and in chloroform fraction at a dose of 140 mg/kg. In the MES test, this plant did not display any significant effect in reducing HLTE duration. According to phytochemical screening,methanolic extract contained alkaloids and tannins. The present study, conducted in mice, indicated that B integerrima has anticonvulsant activity in PTZ-induced seizures. It is concluded that B integerrima may be useful in petit mal epilepsy.
