Abstract

Vellozia piresiana contains β-sitosterol, stigmasterol, taraxerone, compactone, 7β,8β-dihydroxy-3 oxopimar-15-ene and three new diterpenes, one of the pimarane type and the other two with a cleistanthane skeleton. Their structures were deduced on the basis of spectral data and chemical modifications.
