Constituents of the Essential Oils from Lindera glauca (Sieb. et Zucc.) Blume

Abstract

The constituents of essential oils obtained from the root, mesocarp, seed and leaf of L. glauca (Sieb. et Zucc.) Blume grown in Toyono-cho (Osaka prefecture) were investigated by chromato-graphical and spectral methods. From the neutral fraction of the root oil, three compounds isolated: a new sesquiterpene hydrocarbon “aciphyllene” [5 S-(5 α, 8 β, 8 aα)]-l, 2, 4, 5, 6, 7, 8, 8 a-octahydro-3, 8-dimethyl-5-(1-methyl ethenyl)-azulene (V) and two new sesquiterpene alcohols “aci-phyllyl alcohol” [5 S-(5 α, 8 β, 8 a)]-1, 2, 4, 5, 6, 7, 8, 8 a-octahydro-3, 8-dimethyl-α-methylene-5-azulene-methanol (III) and “glaucyl alcohol” [3 S-(3 α, 5 α, 8 α)]-1, 2, 3, 4, 5, 6, 7, 8-octahydro-3, 8-dimethyl-α-methylene-5-azulenemethanol (VIII). The major components of the neutral fraction of root oil were α-guaiene, aciphyllene and δ-guaiene. Those of mesocarp oil were trans-β-ocimene and glaucic acid, and those of the seed oil were decanoic and lauric acid, while the characteristic components of leaf oil were trans-2-hexenoic acid, cis-3-hexenol and trans-2-hexenal.
