Article abstract of DOI:10.1016/0031-9422(95)00013-W

Twenty-seven sesquiterpenes were isolated from leaves of Cryptomeria japonica.The new compounds included elem-1-en-4,11-diol, 11-acetoxyeudesman-4α-ol, eudesmane-5α,11-diol, 3-eudesmene-1β,11-diol, 1β-acetoxy-3-eudesmen-11-ol, 4-eudesmene-1β,11-diol, 1β-acetoxy-4-eudesmen-11-ol, 7-epi-4-eudesmene-1β,11-diol, 1β-acetoxy-4(15)eudesmen-11-ol.Their structures were determined by chemical and spectral methods. - Key words: Cryptomeria japonica; Taxodiaceae; leaves; sesquiterpenes.
