概要

Two new glucosides, named schizonepetosides A (1) and B (2), were isolated from the spikes of Schizonepeta tenuifolia (Labiatae). The structure of 1 was elucidated as (1S, 4R, 8E)-9-O-β-D-glucopyranosyl-p-menth-8 (9)-en-3-one on the basis of chemical and spectral studies. Compound 2 was identified as a glucoside possessing a dioxane ring formed by the double linkage between glucose and the aglycone, (1S, 4R, 8R)-8,9-dihydroxy-p-menth-3-one, by X-ray crystallographic analysis.
