    • Diterpenoids from Baccharis lejía 
      Labbé, Cecilia; Castillo, Mariano; Hernandez, Margarita (1991)
      Seven new neoclerodanes have been isolated from aerial parts of Baccharis lejía. Four are dimeric diterpenoids linked via a C-18 malonate ester. Relevant toxicity toward Artemia salina (brine shrimp bioassay) was observed ...
    • Efecto del porcentaje de retención de agua en la degradación de urea en suelos con distinto contenido de ... 
      González Rojas, Mitza Macarena (Universidad de Chile, 2018)
      El contenido hídrico afecta la actividad ureásica y nitrificante en los suelos, por ende influye en los cambios de pH y potencial de óxido reducción. Dentro de las etapas del ciclo del nitrógeno en el suelo, la degradación ...
