[Studies on the analgesic and anti-inflammatory effect of bornyl acetate in volatile oil from Amomum villosum].

To study analgesic and anti-inflammatory effects of bornyl acetate, the main ingredient of Amomum villosum volatile oil. The analgesic effects were tested by hot-plate and writhing reaction method, the ear swelling caused by dimethylbenzene in mice. Bornyl acetate could restrain writhing reaction caused by acetic acid glacial, lighten the pain caused by hot-plate. It could also suppress ear swelling caused by dimethylbenzene in mice. Bornyl acetate shows analgesic and anti-inflammatory effects.
