Three antifeedants for larvae of the yellow butterfly, Eurema hecabe mandarina de l'Orza, were isolated from Osmunda japonica Thunb. and identified as osmundalin, parasorboside and methyl (3S,5S)-5-hydroxy-3-(beta-D-glucopyranosyloxy)hexanoate. In the course of isolation of the antifeedants, a new glycoside, dihydroisoosmudalin (9), was isolated together with maltol beta-D-glucopyranoside, 2-deoxy-L-ribopyranolactone, 5-hydroxymethyl.2-furfural and glycerin. The structure of 9 was elucidated as (4R,5S)-5-(beta-D-glucopyranosyloxy)hexan-4-olide on the basis of chemical and spectroscopic evidence.
