The volatiles isolated by distillation-extraction from 48 samples of seven liverwort Radula species collected on Azores and Madeira archipelagos and mainland Portugal, as well as one from Switzerland, were analysed by GC and GC-MS. Cluster analysis of the volatiles composition resulted in two major clusters. The chemically very diverse cluster I included the oil samples of Radula aquilegia from Madeira, R. jonesii, R. holtii, R. nudicaulis, R. lindenbergiana as well as R. complanata from Switzerland. Cluster 11 was characterized by high relative amounts of several sesquiterpenes and included the oil samples of R. aquilegia from the Azores as well as R. carringtonii and R. wichurae. 3-Methoxy bibenzyl was the major oil component from R. complanata and R. lindenbergiana. Except for R. aquilegia and the closely related species R. complanata and R. lindenbergiana, the cluster analysis allows distinction of all studied species, indicating the chemotaxonomical value of the volatile oil characters.
