Two new iridoid glucosides from Picrorhiza scrophulariiflora.
Two new iridoid glucosides with 3,4-dihydrocatalpol skeleton, piscrosides A (1) and B (2) together with nine known iridoid glucosides and three known cucurbitacin glucosides, were isolated from the stems of Picrorhiza scrophulariiflora. Their structures were established by MS, 1H NMR, 13C NMR and 2D NMR methods (including HSQC, HMBC and NOESY experiments).
