To elucidate the structure-activity relationships of saponin on fruiting body induction in <I>Pleurotus ostreatus</I>, monodesmosidic saponins comprising a triterpenoid and glucose residues were synthesized. Betulin, a triterpenoid present in <I>Birch</I> bark, was used as the aglycon. The fruiting body induction activity increased with the number of glucose residues, from one to four. The most active betulinic saponin was betulin-3-yl β-<small>D</small>-(4-<I>O</I>-β-<small>D</small>-maltotriosyl)-glucoside.
