Anti-adenovirus Cycloartane Triterpenoids from the Rhizome of Cyathea lepifera

Abstract

A new cycloartane triterpenoid, cyclolaudenyl acetate (2), together with three known compounds, were isolated fromthe rhizome of Cyathea lepifera (J. Sm.) Copel. (Cyatheacea). Its structure was established on the basis of spectral evidence. Cyclolaudenol (1) and cyclolaudenyl acetate (2) showed a significant against adenovirus in vitro at dose of 50 and 10 g/mL, respectively.
