From the crude drug 'takusha', wich is the rhizomes of Alisma plantago-aquatica var. orientale, two new sesquiterpenoids, alismol and alismoxide, have been isolated.Their structures have been estabished on the basis of chemical and physical evidence to be 1β,5β-guaia-6,10(15)-dien-4-ol and 4,10-epoxy-1β,5β-guaia-6-ene, respectively. - Key Word Index: Alisma plantago-aquatica var. orientale; Alismataceae; sesquiterpenoid; guaiane skeleton; alismol; 1β,5β-guaia-6,10(15)-dien-4-ol; alismoxide; 4,10-epoxy-1β,5β-guaia-6-ene
