The results of the six deciduous conifers, the main constituents in the neutral fraction of Ichou were two unknown diterpenes, and two unknown hydrocarbons. Palmitic acid was also found in the acidic fraction. The main constituents in the neutral fraction of Metasequoia wereα-pinene and 3-carene for monoterpenes, caryophyllene for sesquiterpene. The main constituent in the acidic fraction were palmitic acid and an unknown compound for fatty acids, and trans-communic acid and two unknown compounds for diterpene carboxylic acids. The main constituents in the neutral fraction of Rakuushou wereα-pinene for monoterpene, caryophyllene and germacrene-D for sesquiterpenes, and two unknown diterpenes. The main constituent in the acidic fraction were palmitic acid, and trans-communic acid and two unknown compounds for diterpene carboxylic acids. The main constituents in the neutral fraction of Pondsypress wereα-pinene and limonene for monoterpenes, caryophyllene, germacrene-D and an unknown compounds for sesquiterpene, and four unknown diterpenes. The main constituent in the acidic fraction were palmitic acid and an unknown compound for fatty acids, and trans-communic acid and five unknown compounds for diterpene carboxylic acids. The main constituents in the neutral fraction of Suishou wereα-pinene, 3-carene and limonene for monoterpenes, caryophyllene and an unknown compound for sesquiterpenes, and four unknown diterpenes. The main constituent in the acidic fraction were palmitic acid for fatty acids, and three unknown compounds for diterpene carboxylic acids. The main constituents in the neutral fraction of Karamatsu wereα-pinene, sabinene, 3-carene, limonene and bornyl acetate for monoterpenes, germacrene-D and hydroxygermacrene for sesquiterpenes. The main constituent in the acidic fraction were palmitic acid and an unknown compound for fatty acids, and five unknown compounds for diterpene carboxylic acids. The cluster analysis was carried out by using Ward’s method on the 36 major constituents found in neutral and acidic fraction. The results suggested that the all deciduous conifers had a near relationship without Ichou (Ginkgo biloba ).}, pages = {27--45}, title = {落葉性針葉樹葉のヘキサン抽出成分について}, volume = {19}, year = {2022} }
