    • Antioxidant activity of coumarins and flavonols from the resinous exudate of Haplopappus multifolius 
      Torres, René; Faini, Francesca; Modak, Brenda; Zúñiga Urbina, Francisco; Labbé, Cecilia; Guerrero, Juan (PERGAMON-ELSEVIER SCIENCE LTD, 2006-05)
      The antioxidant activity of eight coumarins and two flavonols isolated from Haplopappus multifolius was studied with the DPPH radical method. Results show that a high concentration of phenolic coumarins and the presence ...
    • Antioxidant capacity of abietanes from Sphacele salviae 
      Escuder, B.; Torres, R.; Lissi, E.; Labbé, C.; Faini, Francesca (2002)
      Carnosol 1, rosmanol 2, carnosic acid 3 and 20-deoxocarnosol 4, the main phenolic abietanes present in aerial parts of the Chilean medicinal plant Sphacele salviae were tested for antioxidant activity of measuring the decay ...
    • Antioxidant properties and TLC characterization of four Chilean Haplopappus-species known as bailahuén 
      Vogel, Hermine; González, Mauricio; Faini, Francesca; Razmilic, Iván; Rodríguez, Jaime; San Martín, José; Urbina, Francisco (ELSEVIER, 2005-02-10)
      "Bailahuen" is the common name of a medicinal shrub native to Chile where this resinous herb is widely used for its liver stimulating properties. Although the official species is Haplopappus baylahuen Remy (Asteraceae), ...

      Faini, Francesca; Castillo, Mariano; Torres, M. René (1982)
    • Hybridization in the Genus Baccharis : Baccharis linearis χ B. macraei 
      Faini, Francesca; Hellwlg, Frank; Labbé, Cecilia; Castillo, Mariano (1991)
      On morphological, chemical composition and field distribution studies, the hybrid condition of Baccharis χ intermedia DC. is discussed. B. linearis (Ruiz et Pavón) Pers. and B. macraei Hook, et Arn. are the parental species. ...
    • Labdane diterpenes from Haplopappus illinitus 
      Faini, Francesca; Labbé, C.; Torres, R.; Monache, G. D.; Monache, F. D. (2002)
      A chemical study of aerial parts of Haplopappus illinitus afforded five labdane diterpenoids whose structures were elucidated by high field NMR spectroscopy and 2D techniques. Four of them are dicarboxylic acids previously ...
