 AB    From Isodon loxothyrsa, one new diterpenoid, loxothyrin A, together with
       one known diterpenoid, adenolin B, from I.pleiophyllus, three known
       diterpenoids, coetsoidins A, B and G, and from I. adenoloma, one known
       diterpenoid, longikaurin F, were isolated. The structure determination
       of loxothyrin A, and the unambiguous NMR spectral assignments of the
       known compounds were made by a combination of 1D and 2D NMR techniques
       and computer modelling calculations. The isolates showed potent
       cytotoxic activities.
