N2 - Four new triterpenoids, hopan-29,17a-olide (1), hopan-17a,29-epoxide (2), 3a-hydroxyfilic-4(23)-ene (3), and 2-oxofilic-3-ene (4), were isolated from the dried leaflets of Cyathea spinulosa, together with hop-22(29)-ene (5), fern-7-ene (6), fern-9(11)-ene (7), filic-3-ene (8), hydroxyhopane (9), dryocrassol (10), tetrahymanol (11) and cyclolaudenyl palmitate (12). The structures of the new compounds were elucidated on the bases of spectral data and chemical correlations.
