✦ Synopsis

Chemical constituents of many species of w genus, Aristolw, have been investigated. 1 We wish to describe the isolation and structure of a novel compound, named "Asatone" obtained from Asarum taitonense Hayata. The carbon skeleton of this compound consists of two C6-C3 units. A sample of pulverized material of the whole herb was refluxed with n-hexane for 3hr., and then filtered. The filtrates were concentrated under reduced pressure to give greenish yellow crude crystals which were chromatographed on silica gel and eluted with n-hexane-EtOAc (8 : 1) to give white crystals of asatone (I) in ca.O.Z% yield, m.p. lOl-2"(from n-hexane); W~'='D' -(in MeOH); 2 C24H3208 (m/e 448); X. max(MeOH) 278 and 229nm (6, 5660 and 5100, respectively);
