Abstract

From the herbage ofStachys atherocalyx C. Koch, a new flavonoid glycoside has been isolated — acetylspectabiflaside, with mp 237–242°C. On the basis of acetylation, the formation of a hydroxamic acid, alkaline, and enzymatic hydrolysis, and oxidative degradation, and also the results of UV, IR, and PMR spectroscopy, the structure of 4′,5,7,8-tetrahydroxy-3′-methoxyflavone 7-O-{acetyl-[O-β-D-glucopyranosyl-(1→2)-β-D-mannopyranoside]} has been proposed for acetylspectrabiflaside.
