Picrolemma pseudocoffea

Until 1985, only two quassinoids possessing the C22 basic skeleton were known sergeolide (206) [86] and 15-deacetylsergeolide (207) [87] isolated from the roots of Picrolemma pseudocoffea. Sergeolide... [Pg.461]

Sergeolide (62) 60) is the first natural quassinoid to possess a butenolide function. It was isolated along with the known isobruceine B (45) 45) from the roots of the French Guyanan Simaroubaceae Picrolemma pseudocoffea. The structure of sergeolide was established by analysis of the 400 MHz- H-n.m.r. data and the C-n.m.r. spectrum. [Pg.233]
