Phenolic glycosides and ionone glycoside from the stem of Sargentodoxa cuneata

Four phenolic glycosides, cuneatasides A-D, and one ionone glycoside cuneataside E were isolated from the water-soluble constituents of the stem of Sargentodoxa cuneata. Of these, in vitro tests for antimicrobial activity showed compounds 1 and 2 to possess significant activity against two Gram-positive organisms, Staphylococcus aureus and Micrococcus epidermidis.
