Abstract
Two new phenolic glycosides, syringic acid-4-O-α-L-rhamnoside (1) and ( − )-hydnocarpin-7-O-β-D-glucoside (2), were isolated from the traditional Chinese medicinal herb Inula cappa. The structures of the new compounds were elucidated by means of spectroscopic methods such as 1D, 2D NMR, and HR-ESI-MS.
