Abstract

Phytochemical study on the fruit of Cornus officinalis Sieb. et Zucc. yielded two new iridoid glucosides, named cornusglucoside A (1) and cornusglucoside B (2). The structures of 1 and 2 were elucidated via comprehensive NMR and HR-ESI-MS data analysis. Additionally, their inhibitory effects on IL-6-induced STAT3 activation were assessed.
