A new sweet diterpene glucoside in leaves of Rubus suavissimus

Acta Botanica Sinica 34(4): 315-318

ISSN/ISBN: 0577-7496

From leaves of Rubus suavissimus, two minor ent-kaurane type diterpene glucosides were isolated in addition to the major sweet principle, rubusoside. The bitter glycoside was identified as surgeroside which has been isolated form leaves of Ilex sugerokii var. brevipedunculata etc. The new glucoside named suavioside-A has a sweet taste and the structure was elucidated as 3-alpha,16-beta,17-trihydroxy-ent-kaurane-17-0-beta-D-glucopyranoside.
