Abstract
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.This publication has 0 references indexed in Scilit:
