✦ Synopsis

During the search for the lipase formation stimulating factor in Sclerotinia libertiana, one of the authors (Y .S.) succeeded in isolating the active substance, C13H1404 (MS m/e 234), m.p. 123' , [ a]D+7.850, which was designated sclerin (2). Further study on this compound revealed a number of interesting physiological activities-specially the growth promoting effect for varidw plants. The second minor metobolite,C,2H1404, m.p. 163' , was isolated from the mycelium by a larger scale extraction, and the name sclerolide is proposed for it. The present paper concerns with the structure elucidations of sclerin and sclerolide. Sclerin exhibited the following spectral properties:
