Two sesquiterpenic alcohols, cyperol and isocyperol, have been isolated from nutgrass (Cyperus rotundus (Cyperaceae)) and shown to have stereostructures I and IV, respectively, by means of spectral determinations and by transformations to α-cyperone (II) and 4β (H)-eudesman-3-one (IX), respectively.
从坚果草(香柏科)中分离出了两种倍半萜醇,即香柏醇和异香柏醇,并通过光谱测定和转化为 α-cyperone (II) 和 4β (H)-eudesman-3-one (IX),证明它们分别具有立体结构 I 和 IV。
