Abstract
Two new iridoid esters, named patriheterdoid B, C, have been isolated from the rhizomes and roots of Patrinia heterophylla Bunge. Their structures were elucidated by extensive spectroscopic technologies. Together with patriheterdoid B, C, two known analogues have been isolated and identified by means of mass spectrometry and 1H and 13C NMR spectrometry. These compounds showed cytotoxic activity against SGC-7901, PC3 cell lines.
