Article abstract of DOI:10.1016/S0040-4020(01)87350-6

From the aerial parts of Chiliotrichium rosmarinifolium in addition to known compounds nine diterpenes were isolated, three isolabdanes, three seco-isolabdanes, a cis-clerodane, a rearranged di-lactone and a geranyl geraniol derivative.The aerial parts of Nardophyllum lanatum gave two of the new diterpenes and three further diterpenes which are closely related to those of the Chiliotrichium species.Furthermore two new geranyl geraniol derivatives were present.The structures were elucidated by highfield NMR specroscopy.
