Another component of the essential oil of the pepper tree (Pseudowintera colorata) has been isolated and assigned the rearranged bicyclofarnesane structure (50). ° Cyclonerotriol (52) has recently been isolated from Fusarium culmorum where it co-occurs with cyclonerodiol (51) cf. Vol. 1, p. 58 Vol. 2, p. 72 Vol. 3, p. 

A second proof comes from wounding experiment of Pseudowintera colorata Raoul (Gould et al, 2002b). In contrast to green leaves, the red ones, enriched in vacuolar antho-cyanins, flavonols, dihydroflavonols, and HCAs, alleviate intensity and duration of the localized burst of H2O2 induced in palisade mesophyll cells by wounding. Vacuolar phenolics participate to scavenge ROS.
