 note = {論文(Article), The leaf n-hexane extracts (neutral and acidic fractions) in Kurobe (Thuja standishii) collected from Mt. Kamikura in Yamagata prefecture were analyzed by GC and GC-MS comparing with four other conifer leaves.
The results showed that the main constituents in the neutral fraction were α-pinene, sabinene and bornyl acetate for monoterpenes, and hibaene, dolabradiene and nezukol for diterpenes. There was a variation in the contents of nezukol among individuals. The results also showed that the main constituents in acidic fraction were palmitic acid for fatty acid and trans-communic acid for diterpene carboxylic acid, and variation was also found in the content of trans-communic acid among individuals. These results suggested that Kurobe have chemotypes.
As the results of the other conifers, the main constituents in the neutral fraction of Sugi (Cryptomeria japonica) were α-pinene, sabinene and limonene for monoterpenes, elemol and hydroxygermacrene for sesquiterpenes, and kaurene for diterpene. Unknown diterpene carboxylic acids were also found as main constituents in the acidic fraction. The main constituents in the neutral fraction of Hiba (Thujopsis dolabrata) were sabinene for monoterpene, elemol for sesquiterpene, and hibaene and dolabradiene for diterpenes. The main constituent in the acidic fraction was trans-communic acid for diterpene carboxylic acid. The main constituents in the neutral fraction of Hinoki (Chamaecyparis obtusa) were sabinene, β-myrcene, limonene, bornyl acetate and α-terpinyl acetate for monoterpenes, elemol for sesquiterpene, and hibaene for diterpene. Unknown lignans were also found as main constituents in the neutral fraction. Hinoki acid, sesquiterpene carboxylic acid, was also found as a main constituent in the acidic fraction. The main constituents in the neutral fraction of Kouyamaki (Sciadopitys verticillata) were α-pinene for monoterpene, and sclarene, kaurene and six unknown furano-type compounds for diterpenes. trans-Communic acid and unknown diterpene carboxylic acids were also found as main constituents in the acidic fraction.
The cluster analysis was carried out by using Ward’s method on the 53 major constituents found in neutral and acidic fraction. The results suggested that Kurobe (Thuja) had a near relationship with Hiba (Thujopsis), and far relationships with Kouyamaki (Sciadopitys) and Hinoki (Chamaecyparis).},
