Three new compounds, peucedalactone, C_<16>H_<18>O_5,m.p. 159.0°, isopeucedalactone, C_<16>H_<18>O_5,m.p. 122.5°, and peucin, C_<15>H_<14>O_4,m.p. 291.5〜292.0°, were isolated from the ether extract of Peucedanum japonicum THUNB. Peucedalactone and isopeucedalactone were obtained, together with a short-chain fatty acid (p-acid), after saponification of a resinous distillate, b.p_1 210〜220°, of the extract. All these three new compounds were optically active and seemed to have coumarin-like skeleton. Some of their properties were also described. Bergapten and palmitic acid were isolated besides above compounds.
