, p. 603 - 608 (1995)
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.

, p. 5907 - 5910 (1989)
Novel sesquiterpene-neolignans, eudesobovatols A (1) and B (2) isolated from Magnolia obovata have been assigned structures on the basis of detailed spectroscopic analyses and chemical degradation, and eudesobovatol A has been found to exhibit neurotrophic activity at 1E-5 M 1E-7 M on neuronal cell culture system of fetal rat cerebral hemisphere.
Biotransformation of (+/-)-4,8-dimethylcyclodeca-3(E),7(E)-dien-1β-ol and (+)-Hedycaryol by Cichorium intybus

The biotransformation of the synthetic (E,E)-1,5-cyclodecadienol 5 and (+)-hedycaryol (11) by a root suspension of fresh chicory has been investigated.Incubation of 5 with a root suspension gave a 2:1 mixture of epimeric eudesmanediols 7a and 7b whereas 11 was selectively converted into cryptomeridiol (12).An explanation for the obtained results is proposed.
