Eight new resin glycosides, pescapreins X-XVII (1-8), were isolated from a lipophilic fraction of an ethanol extract of the entire plant of beach morning glory, Ipomoea pes-caprae. Their structures were elucidated by spectroscopic data analysis and by chemical transformation. These compounds were evaluated biologically in terms of cancer cell line cytotoxicity, antibacterial and antifungal activity, and effects on the mu-opioid receptor.
