Two serrulatane diterpenes have been isolated from Eremophila duttonii. The structure of (3R)-serrulat-14-ene-3,7,8,20-tetraol, a compound suitable for conversion into the seco-pseudopterosins, was established on the basis of spectroscopic and chemical evidence. Further data are provided for serrulat-14-ene-7,8,20-triol and its derivatives.
