Desde de las partes aéreas de Laretia acaulis (Cav.) Gill et Hook hemos aislado azorellanol y un nuevo diterpenoide 7-desacetilazorellanol. Su estructura esta basada en la comparación de sus datos espectroscópicos con los de azorellanol y transformaciones químicas. Azorellanol y 7-desacetilzorellanol muestran una marcada actividad inhibitoria frente a los trofozoitos del protozoo parásito Toxoplasma gondii. La dosis inhibitoria 50 (DI50) de azorellanol es 54 myM y para 7-desacetylazorellanol 42 myM

In addition to azorellanol a new diterpenoid 7-deacetylazorellanol, has been isolated from the aerial parts of Laretia acaulis (Cav.) Gill et Hook (Umbelliferae). Its structure was based on spectroscopic comparison with azorellanol and chemical grounds. Azorellanol and 7-deacetylazorellanol showed marked inhibitor activity against trophozoites of protozoan parasite Toxoplasma gondii. The 50 % inhibitory dose for azorellanol was calculated in 54 muM and for 7-deacetylazorellanol was 42 mM.
