The hexane and methanol-extracts of inner and outer harks of sugi (Cryptomeria japonica) were analyzed. The neutral fraction of the bark extracts consisted mainly of phyllocradanol and abietatriene type diterpenes. The barks contained a small amount of sandaracopimarinol, known as a major component in heartwood of sugi. An acidic solid was the major component in the methanol extract of barks. Based on alkali fusion and ozonolysis, it was surmised that the solid was a suberin polymer containing carboxyl groups and ester bonds of aliphatic acid and an aromatic ring.
