Alicyclic Diterpenes fromSolidagoSpecies

Abstract
The aerial parts of Solidago drummondii afforded in addition to known compounds like germacrene D and β-caryophyllene, eight alicyclic diterpenes all derived from geranylgeraniol. The main constituent was also isolated from S. racemosa and S. flexicaulis. The structures were elucidated by highfield 1H-NMR spectroscopy.
