Summary

Saurin, a sesquiterpene isolated fromSaussurea pulchella Fisch., has the composition C15H15O5 · 0.5 H2O. It It contains a γ-lactone ring, two hydroxy groups, two terminal methylene groups, and a keto group in a five-membered ring. Dehydrogenation with selenium gives chamazulene and, apparently, guaiazulene. Two possible structural formulas of saurin, (Ia) and (Ib), are proposed.
