Abstract

Essentially complete analyses are reported of the sesquiterpene fractions from the leaf oils of Pinus longifolia, P. pinaster, P. thunbergii, P. densiflora, Chamaecyparis nootkatensis and C. obtusa and of oil from the liverwort S cap a ni a undulata. These species have been recorded as sources of longifolene and related compounds but the present results differ considerably from those of the previous (often incomplete) analyses. The best sources of longifolene and its relatives were P. pinaster and S. undulata (16; 46 % of the steam volatile oil respectively) and enantiomorphic compounds were found in the two species.
