A New Monoterpene Glucoside ℓ-Menthyl 6′-O-acetyl-β-D-glucoside

ABSTRACT l-Menthyl-6′-O-acetyl-β-D-glucoside has been isolated and characterized as a new constituent of a leaf extract of “Wasenami,” a Japanese cultivar of Mentha arvensis L. var. piperascens Malinv. Its structure was confirmed by 13C-NMR. β-Sitosteryl-β-D-glucoside and l-menthyl-β-D-glucoside were also isolated and characterized along with the 6′-O-acetyl derivative.
