M. Wichlacz et al., A caryophyllene-related sesquiterpene and two 6,7-seco-caryophyllenes fromliquid cultures of Hebeloma longicaudum, J NAT PROD, 62(3), 1999, pp. 484-486
Three new caryophyllene-related sesquiterpenes, hebelophyllenes D (1), E (2
), and F (3), were isolated from liquid cultures of the ectomycorrhizal fun
gus Hebeloma longicartdum. Their structures were determined by modern spect
roscopic methods. Hebelophyllene D has a tricyclo[5.4.0.0(2,5)]undecane ske
leton. while hebelophyllenes E and F are the first naturally occurring 6,7-
seco-caryophyllenes.
