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