Popis: Two new iridoid tetramers with four glucosides, dipsanosides H (1) and I (2), as well as one new bis-iridoid glucosides dipsanosides J (3), along with four known polymer iridoid glycosides dipsanosides A (4) and B (5), pterocephaline (6), triplostoside A (7) were isolated from Dipsacus asper. Their structures were determined by analysis of 1D and 2D NMR data. All of them were found to be inactive in anti-inflammatory activity.
