Two bisabolene sesquiterpenes (1 and 2), two nor-sesquiterpene ketones (3 and 4) and one humulene epoxide (6) were identified from the Taiwanese liverwort Bazzania tridens. Among them, 3 was novel, and 2, 4 and 6 were reported for the first time from a natural source. Their structures were mainly elucidated by analysis of various NMR spectra.
