FERN CONSTITUENTS: NEW CYCLOARTANE TRITERPENOIDS, (24R)-CYCLOLAUDENYL ACETATE AND (24R)-CYCLOMARGENYL ACETATE, AND THEIR CORRESPONDING ALCOHOLS AND KETONES, ISOLATED FROM POLYPODIUM FORMOSANUM

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.
