The rhizomes of Curcuma xanthorrhiza ROXB, are used in Indonesian folk medicine as cholagogues, aromatic stomachics, analgesics, a rheumatic remedy, etc. The present study was carried out to elucidate the antiinflammatory effect of the methanol extract obtained from these rhizomes and its active principles. The methanol extract was partitioned between ether and water, and then the ether-soluble fraction was extracted with n-hexane. The n-hexane-soluble fraction was chromatographed (fr. I-IV), fr. II was rechromatographed (fr. V-VII), and then fr. V was rechromatographed (fr.VIII-X) by silica gel column chromatography. The antiinflammatory activity of these fractions was investigated on carrageenin-induced edema in rats and acetic acid-induced vascular permeability as well as the writhing symptom in mice. The methanol extract (p.o.) showed both an antiinflammatory activity and an analgesic activity and these activities shifted successively to the ether-soluble fraction, the n-hexane-soluble fraction, fr. II, V and IX. The chemical structure of fr. IX was identified as germacrone. These results suggest that the antiinflammatory action of Curcuma xanthorrhiza is the result of the germacrone that it contains.
