Abstract: The structure and stereochemistry of two plienolic compounds from aster tataricus were determined employing a variety of NMR experiments. Phase-sensitive COSY experiment was sunasfully used to resolve the crowded, strong coupled spin systems.The conformation of compound Ⅰ was discussed with the aid of molecular mechanism calculations.
