Two new ionone glucosides, named apocynosides I and II, were isolated from the roasted leaves of Apocynum venetum L. together with nine known compounds. The absolute stereostructures of apocynosides I and II were determined by chemical and physicochemical evidence, which included the application of a modified Mosher’s method and the circular dichroism helicity rule.
