γ-Polypodatetraene (6), the first example of a bicyclic triterpenoid hydrocarbon, has been isolated from fresh leaflets of Polystichum polyblepharum and its structure has been elucidated on the basis of Mass, ^1H- and ^<13>C-NMR spectral analyses. More than 30 species and 40 hybrids in the genus Polystichum are known in Japan. Further investigation on the some species of this genus, led us to the finding that Polystichum species contained mainly hopane and migrated hopane triterpenoids, viz. hop-22(29)-ene (1), fern-9(11)-ene (2), hydroxyhopane (3), dryocrassol (4), dryocrassyl acetate (5) along with the other type triterpenoids, viz. γ-polypodatetraene (6), squalene (7), α-polypodatetraene (8), dammara-18(28),21-diene (9) and a diterpenoid, phytol (10). On the basis of their triterpenoid (6, 8) and diterpenoid (10) profiles, those 16 Japanese Polystichum species could be divided into three groups chemotaxonomically.
