    Diterpenoids from Salvia miltiorrhiza.[Pubmed: 10820810]

    METHODS AND RESULTS:
    The abietane diterpenoid, Neocryptotanshinone II, and the known 6,12-dihydroxyabieta-5,8,11,13-tetraen-7-one were isolated as minor components from the roots of Salvia miltiorrhiza. Their structures were established on the basis of spectral evidence.
