Ten samples of sugi (Cryptomeria japonica D. Don) wood from different localities were extracted with acetone, and the hexane or ether soluble parts of the extracts were compared. The obisugi variety yielded more extracts and components than those of any other locality. Commonly, sesquiterpene alcohols were minor components, and cubenol and/or epicubenol in addition to an unidentified secondary alcohol were present. However, the obisugi variety contained additionally, much cubebol, 4-epicubebol, in addition to elemol, cedrol, eudesmols and so forth. 2,7 (14),10-Bisabolatrien-1-ol-4-one (50) and 1,3,5,7(14),10-bisabolapentaen-2-ol (51b) were found as new compounds.The main acidic component was sandaracopimaric acid. The ratio of isopimaric acid to sandaracopimaric acid varied with samples and was very low in the obisugi variety. A race which contain much myrtenic acid was discovered.Extract from the part stained by Guignardia dieback yielded much extract in which the sesquiterpene alcohols increased. Extract from sapwood was small, and the composition was different from that of heartwood.
