A cardenolide glycoside was isolated from the aerial parts of Gomphocarpus sinaicus Boiss. along with the previously known cardenolide glycoside 15β-hydroxycalotropin. The structure of the new glycoside was elucidated on the basis of spectroscopic data and comparison of NMR data with those of the congeners. It was identified as 15β-hydroxy-7,8- dehydrocalotropin.
