Abstract
Two new diterpenoids were isolated from the New Zealand liverwort Lepidolaena clavigera. Spectroscopic studies identified the structures as atisanes 1 and 2, with an unprecedented level of oxygenation. This is the first report of the atisane skeleton from a liverwort. Compound 2 showed cytotoxic and insecticidal activity. [structure: see text]
