Wei–Chang–An–Wan (WCAW) as one of them has been used for treating various gastrointestinal diseases several decades. The secondary WCAW is progress so to interpret the effective material basis or find new pharmacological activity.Objective: To evaluate antinociceptive effect methanol extract (ME) well four fractions (P.E., EtOAc, n-BuOH, H2O) obtain information on correlation between contents effect.Materials methods: ME was divided into parts extracted by petroleum ether, ethyl acetate n-butanol. Antinociceptive activity evaluated three models acetic acid–induced writhing, formalin hot-plate test mice after repetitive administration at 200, 400 800 mg/kg, P.E. 132 mg/kg, EtOAc 106 mg/kg, n-BuOH 176 mg/kg H2O six days. chemica...
