title: Water-soluble constituents from the bark of Elaeagnus pungens and their cytotoxic activities.
abstract: Three new water-soluble compounds, pungens A-C, along with four known compounds including two phenol glycosides, one secoiso-flavanol and one phenol ether, have been isolated from the bark of Elaeagnus pungens. Among them, pungen C (7) (200 microg/ml) was tested in SGC-7901 and BEL-7404 tumor cell lines, and showed moderate cytotoxic activity. The structures of the new compounds were elucidated on the basis of spectroscopic data and chemical evidence.
