β¦ Synopsis
From the aerial parts of Chiliotrichium rosmarinifolium in addition to known compounds nine diterpenes were isolated, three isolabdanes, three seco-hvolabdanes, a c&clerodane, a rearranged dilactone and a geranyl geraniol derivative. The aerial psrts of Rardo lum lanatum gave two of the new diterpenes and three further aE$% which are closely related to those of the Chiliotrichium species. Furthermore two new geranyl geraniol derivatives were present. The structures were elucidated by highfield NUR spectroscopy.
