Abstract

The methanol extract of Kalopanax pictus bark was evaluated on anti-inflammatory and anti-nociceptive activities in animal models. The extract produced a significant inhibition of vascular permeability at doses of 1 and 3 g/kg, p.o. in mice and of leucocyte emigration at doses of 0.15 and 0.3 g/rat, s.c., in CMC-pouch of rats. However, the extract (0.25 and 3 g/kg, p.o.) did not show anti-inflammatory activity in carrageenan induced edema of rats. The extract at a dose of 2.5 g/kg, p.o. inhibited writhing syndromes, whereas it did not exhibit anti-nociceptive in Randall-Selitto assay. The methanol extract was then partitioned with n-hexane, chloroform, ethyl acetate and butanol to give each soluble fraction and finally water soluble fraction. Among those fractions, the inhibitory effect on vascular permeability in mice was produced by ethyl acetate soluble fraction in this activity-guided fractionation. The methanol extract showed low acute toxicity in mice. These results suggest that the methanol extract of Kalopanax pictus bark has an anti-inflammatory activity which is distributed in the ethyl acetate fraction.
