T. Wada et al., STUDIES ON CHEMICAL-COMPONENTS OF MUSHROOMS .5. 2 CHEMOTYPES OF BOLETINUS CAVIPES, Bioscience, biotechnology, and biochemistry, 59(6), 1995, pp. 1036-1039
Eight terpenes, including four new compounds, were isolated from Bolet
inus cavipes collected from two different districts (strains A and B)
in Japan, Their structures were determined by spectroscopic and chemic
al methods, these compounds being geranylgeraniol (diterpene) or farne
sol (sesquiterpene) derivatives. The geranylgeraniol derivatives were
isolated from strain A, while the farnesol derivatives were isolated f
rom strain B, These results indicate the presence of two chemotypes of
the fungus B. cavipes.
