title: Repraesentins D, E and F, new plant growth promoters from Lactarius repraesentaneus.
abstract: 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.
