    • Azorellanol: A diterpenoid with a new carbon skeleton from Azorella compacta 
      Loyola, Luis Alberto; Bórquez, Jorge; Morales, Glauco; San Martín Barrientos, Aurelio; Manríquez, Víctor; Wittke, Oscar (Elsevier Ltd, 1998)
      A new diterpenoid, azorellanol (5), was isolated from the whole plant of Azorella compacta (Umbelliferae). The stricture was established by using mainly one- and two-dimensional NMR techniques, whereas the absolute ...
    • 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, ...
    • 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 ...
    • New diterpenes from Azorella spinosa 
      Astudillo, Luis; Gutiérrez, Margarita; Quesada, Luisa; San Martín Barrientos, Aurelio; Espinoza, Luis; Peñailillo, Patricio (2014)
      Two new diterpenes,2-acetoxy-13-hydroxy-mulin-11-ene and 2-acetoxy-mulin-11, 13-diene,have been isolated from the aerial parts of Azorella spinosa and their structures determined by spectroscopic and conventional chemical ...
    • 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, ...
