  Abstract From the rhizomes of Polypodium formosanum, new triterpenoids of the cycloartane group, (24R)-cyclolaudenol and (24R)-cyclomargenol, were isolated as the corresponding acetates, alcohols and ketones, and their structures were established. Also, from the rhizomes of P. niponicum eight acetates of cycloartane derivatives and two acetates of new methyl sterols were isolated and characterized

  New tetracyclic triterpenoids, (24R)-cyclolaudenyl acetate(Ia) and (24R)-cyclomargenyl acetate(Ib), and their corresponding alcohols(IIa, IIb) and ketones(IIIa,IIIb) were isolated from the rhizomes of Polypodium formosanum. The structure of Ia and Ib were deduced by chemical and spectroscopic methods to be (24R)-24-methylcycloart-25-en-3β-yl acetate and (24R)-24-ethylcycloart-25-en-3β-yl acetate, respectively.
