Resumo:
A new bis-diterpene, moldenin (6), derived from the esterification of 3-oxo-8(17)-15-labdenic acid with 3β-hydroxy-8(17)-15-labdenol, four normal-labdane diterpenes 1–4, and betulinic acid were isolated from the stems of Moldenhawera nutans. The structures were established on the basis of their spectral data.
