Repraesentins D, E and F, new plant growth promoters from Lactarius repraesentaneus.
Three new plant growth regulatory sesquiterpenes were isolated from the Lactarius repraesentaneus fungus. Their structures were elucidated to be lactarane sesquiterpenes, namely repraesentins D (1) and E (2), and a protoilludane-related sesquiterpene, namely repraesentin F (3). Repraesentin E (2) showed the strongest promotion activity, 164% at 3.6 microM, of the three compounds toward the radicle elongation of lettuce seedlings.
