    • Azorellane diterpenoids from laretia acaulis, and its toxoplasmacidal activity 
      Loyola, Luis A.; Borquez, Jorge; Morales, Glauco; Araya, Jorge; Gonzalez, Jorge; Neira, Ivan; Sagua, Hern A.N.; San Martín Barrientos, Aurelio (Sociedad Chilena de Quimica, 2001)
      In addition to azorellanol a new diterpenoid 7-deacetylazorellanol, has been isolated from the aerial parts oiLaretia acaulis (Cav.) Gill et Hook (Umbelliferae). Its structure was based on spectroscopic comparison with ...
    • Diterpenoids from Azorella compacta 
      Loyola, Luis A.; Bórquez, Jorge; Morales, Glauco; San Martín Barrientos, Aurelio (1997)
      In addition to mulinolic acid, a new diterpenoid, mulin-11,13-dien-20- oic acid, has been isolated from the aerial parts of Azorella compacta. Its structure was based on a spectroscopic comparison with mulinolic acid and ...
    • Diterpenoids from Azorella yareta and their trichomonicidal activities 
      Loyola, Luis A.; Bórquez, Jorge; Morales, Glauco; Araya, Jorge; González, Jorge; Neira, Ivan; Sagua, Hernan; San Martín Barrientos, Aurelio (2001)
      Diterpenoids with trichomonicidal activity were isolated from the aerial parts of Azorella yareta Hauman. One was 13β-hydroxyazorellane, together with the known constituents mulinolic acid, mulin-11,13-dien-20-oic acid, ...
    • Experimental antihyperglycemic effect of diterpenoids of llareta Azorella compacta (umbelliferae) phil in rats 
      Fuentes, Nelson L.; Sagua, Hernan; Morales, Glauco; Borquez, Jorge; San Martín Barrientos, Aurelio; Soto, Julia; Loyola, Luis A. (2005)
      Aqueous or ethanol infusions of Azorella compacta (llareta) in common with many other plants have been used as antidiabetic in the popular medicine in the altiplanic region of Chile. In order to determine if the diterpenic ...
    • Mulinane-type diterpenoids from Azorella compacta display antiplasmodial activity 
      Loyola, Luis A.; Bórquez, Jorge; Morales, Glauco; San Martín Barrientos, Aurelio; Darias, Jose; Flores, Ninoska; Giménez, Alberto (2004)
      Two mulinane-type diterpenoids were isolated from Azorella compacta; namely 20-hydroxymulin-11,13-dienyl acetate and 13,14-dihydroxymulin-11-en-20-oic acid. The structures were elucidated by analysis of their spectroscopic ...
    • Mulinane-type diterpenoids from Laretia acaulis 
      Loyola, Luis A.; Bórquez, Jorge; Morales, Glauco; San Martín Barrientos, Aurelio (2000)
      In addition to the known mulinolic acid and mulin-11, 13-dien-20-oic acid, 13-epimulinolic acid has been isolated from the aerial parts of Laretia acaulis (Cav.) Gill et Hook (Umbelliferae). Its structure was based on ...
    • Triterpenoids from Azorella trifurcata (Gaertn.) pers and their effect against the enzyme acetylcholinesterase 
      Areche, Carlos; Cejas, Patricia; Thomas, Pablo; San Martín Barrientos, Aurelio; Astudillo, Luis; Gutiérrez, Margarita; Loyola, Luis A. (Sociedade Brasileira de Quimica, 2009)
      The inhibition of the enzyme acetylcholinesterase is considered as a strategy for the treatment of Alzheimer's disease, senile dementia, ataxia, and myasthenia gravis. Three lanostane- and two cycloartane-type triterpenes, ...
