title: Iridoid glucosides from Caryopteris mongholica.
abstract: Two new iridoid glucosides, 8-acetyl-6'-O-(p-coumaroyl) harpagide and 6'-O-(p-coumaroyl) antirrinoside, were isolated from the Caryopteris mongholica, together with two known iridoid glucosides, 8-acetylharpagide and harpagide. Their structures were elucidated, mainly by interpretation of their spectroscopic data (UV, IR, MASS, 1H, 13C, 1H/1H-COSY, HMQC, HMBC and NOESY NMR) and chemical methods.
