Besides three known flavonoid glycosides, a new monoterpene glucoside named schizonepetoside C (3) was isolated from the spikes of Schizonepeta tenuifolia BRIQ. (Labiatae), as an amorphous powder. The structure of 3 was established as (1S,4E)-9-O-β-D-glucopyranosyl-p-menth-4(8)-en-3-one by chemical methods and spectral analyses.
