A full assignments. of the proton resonance signal of rhodojaponin-Ⅱ isolatedfrom Chinese azalea (Ericaceae Rhododendron Molle G. Don) has been accomplished by me-ans of the ~1H-~1H COSY, DQF ~1H-~1H COSY, long range ~(13)C-~1H COSY and ~1H-~1H NOESYtechniques. In addition, some earlier reported ~(13)C signal assignments of the compound have beencorrected based on the results of ~1H-~1H NOESY and ~(13)C-~1H COSY.
