Abstract
Essential oils of the young trees of Metasequoia glyptostroboides Hu et Cheng were examined. The yield of oils from shoots was 0.08-0.09%, and the oils contained l-α-pinene as high as 80.3-86.1%. The branchlet oil was obtained in the yeild of 0.002%, and contained 22.7% of β-pinene, 11.8% of α-terpinyl acetate, and 5.3% of α-calacorene, together with 7.0% of 1-octen-3-yl acetate and 6.0% of 1-octen-3-ol. The yield of trunk oil was 0.009%, and the main constituents determined were calamenene and α-cadinol, and others have not yet been identified.
