A New Coumarin Glucoside from Daphne arisanensis.

Abstract

A new coumarin glucoside named daphneside was isolated along with two known coumarin glucosides, daphnin and daphnetin-8-glucoside, and two known phenylpropanoid glucosides, syringin and syringinoside, from a water-soluble fraction of Daphne arisanensis HAYATA (Thymelaeaceae) collected in Taiwan. The structure of daphneside was elucidated by spectroscopic and chemical methods.
