A trisaccharaide and four new glycosidic acids named cuscutic acids A-D along with known organic acids were isolated from the alkaline hydrolysate of the ether-insoluble resin glycoside-like fraction of the seeds of Cuscuta chinensis, and their structures were determined on the basis of chemical and physical data. A trisaccharide and four new glycosidic acids, named cuscutic acids A-D, along with known organic acids, acetic acid, propionic acid, (2 S)-2-methylbutyric acid, tiglic acid, (2 R, 3 R)-nilic acid, (11 S) convolvulinolic acid and (11 S)-jalapinolic acid have been isolated from the alkaline hydrolysate of the ether-insoluble resin glycoside-like fraction of the seeds of Cuscuta chinensis. The compounds were characterized on the basis of chemical and physical data.
