Examinations were made on the glucoside (colorless crystalline powder, m.p. 300-301°, [α]D30-26° (pyridine)), obtained from the nonsaponifiable matter of the crude oil of Pinellia ternata BREIT. (Japanese name “Hange”). Analytical values of this glucoside correspond to the formula of C35H60O6 and its hydrolysis with ethanolic hydrochloric acid afforded β-sitosterol as the aglycone and d-glucose as the sugar, which were identified with authentic samples. β-Glucoside tetraacetate was prepared from acetobromoglucose and β-sitosterol and identified with the tetraacetate obtained from the plant product. These experiments have proved that the glucoside obtained from the plant is β-(β-sitosteryl)-D-glucoside.
