Abstract

A novel iridoid glucoside was isolated from the root of Phlomis umbrosa Turcz. (Labiatae) 'Sok-dan' and named as Umbroside. It was obtained as amorphous powder and its molecular formula is C_{19}H_{18}O_{12}$. By enzyme hydrolysis it produced a stable aglucone and ${\beta}-D-glucose$. The structure of Umbroside was determined as 8-O-acetyl shanzhiside methyl ester. Antitumor activity of Labiatae plants was also tested.
