Abstract

Abstract: A new arbutin derivative, namely dunalianosides J (1 ), along with six known compounds, arbutin (2 ), robustaside A (3 ), 6′- O -caffeoylarbutin (4 ), dunalianoside D (5 ), kaempferol 3- O - β -D-glucopyranoside (6 ) and kaempferol 3- O - β -D-sambubioside (7 ) were isolated from the leaves of Vaccinium dunalianum Wight (Ericaceae). The structure of1 was elucidated by extensive 1D and 2D NMR, HR-MS and CD spectroscopic analyses. In which, kaempferol 3- O - β -D-sambubioside (7 ) was isolated from the genus Vaccinium for the first time. Abstract :
