摘要：

Maragenins I, II and III, new pentacyclic triterpenes from Marah macrocapus (Greene) Greene, are shown to be respectively Δ12-, Δ12,17- and Δ17-3β-hydroxy-16-oxo-28-norloeananes on the basis of chemical and spectroscopic evidence. The structural proposal for maragenin I is confirmed by synthesis from echinocystic acid. © 1979.
