The structure of davallialactone (1), obtained from the rhizomes of a fern, Davallia mariesii MOORE, was revised on the basis of chemical and spectroscopic evidence. Also, the absolute stereochemistry of 1 was determined to be 5'R, 6'S from a circular dichroism (CD) study of dihydrodavallialactone (2).
