Rhizome of Polypodium amamianum was shown to contain fern-7-ene(1), hop-22(29)-ene(2), olean-18-ene(3), olean-12-ene(4), taraxer-14-ene(5), multiflor-8-ene(6), multiflor-7-ene(7), friedel-3-ene(8), 22-acetoxyhopane(9), germanicyl acetate(10), cycloeucalenyl acetate(11), cyclolaudenyl acetate(12), cyclomargenyl acetate(13), 7α-hydroxytaraxer-14-ene(14), 17αH-trisnorhopan-21-one(15), 2-oxofriedel-3-ene(17), cyclolaudenone(18) and cyclomargenone(19). They were either individually isolated or identified in the extract by means of GC-MS and ^1H-NMR spectra. Some of these compounds, especially triterpenoids of oleanane or migrated oleanane series contained in P. amamianum suggest close chemotaxonomical relationship between this fern and P. niponicum and P. formosanum. From leaves of the fern, P. amaniamum, two new diterpenoids, (13R)-13, 14-dihydroxyalep-terolic acid(23) and its acetate(22) were isolated and identified. Since 22 and 23 are only in P. amamianum, those two compounds may provide a useful means for the chemotaxonomical identification of this fern.
