A diterpene quinone from the bark of Cryptomeria japonica

Phytochemistry, 2002
A diterpene, cryptoquinone, was isolated from the bark of Cryptomeria japonica, the structure, 7,11,14-trioxoabieta-8,12-diene, was established by spectral analyses and X-ray crystallography. This diterpene quinone showed moderate antifungal activities against Pyricularia orizae and Alternaria alternata, and cytotoxic activity against mouse lymphoid ...

Translocation of 133Cs administered to Cryptomeria japonica wood

Science of The Total Environment, 2017
To reveal the in planta behaviour of caesium (Cs), the stable isotope 133Cs was administered into 3-year-old Cryptomeria japonica seedlings by the application of 133CsCl aqueous solution to the bark surface. The administered 133Cs was quantified by ICP-MS measurements, which showed transportation of 133Cs in an ascending direction in the stem ...
