[摘要]:Two unusual monoterpenes, densispicnins A (I), B (II), together with the four known monoterpenes, mussaenoside, yuheinoside, mussaenin A, argyol, were isolated from the whole plant of Pedicularis densispica Franch. The structures of densispicnin A and densispicnin B were elucidated mainly based on spectral data including 1D-, 2D-NMR (HSQC, HMBC, ROESY) and MS expts. |
