摘要：

From the wood of Herrania cuatrecasana two novel triterpenoids have been isolated and structurally elucidated mainly by ID and 2D NMR spectroscopy and X-ray crystallography. The two new compounds have been identified as 3 beta,25-epoxy-25-hydroxy-14-taraxerene-1-one (1) and 6 alpha,25-dihydroxy-3 beta,25-epoxy-14-taraxerene-I, 16,21-trione (2) and were named as herranone (I) and herrantrione (2).
