Two unusual monoterpenes, densispicnins A (1), B (2), together with the four known monoterpenes, mussaenoside (3), yuheinoside (4), mussaenin A (5), argyol (6), were isolated from the whole plant of Pedicularis densispica Franch. The structures of 1 and 2 were elucidated mainly based on spectral data including 1D-, 2D-NMR (HSQC, HMBC, ROESY) and MS experiments.
