    • (25R)-Isonuatigenin, an unusual steroidal sapogenin from Vestia lycioides 
      Faini, Francesca; Torres, René; Castillo, Mariano (1984)
      (25R)-Isonuatigenin, a 5-spirosten-3β,25-diol, was isolated from aerial parts of Vestia lycioides. Its structure was elucidated mainly by 1H NMR and 13C NMR spectroscopy. A mixture of (25R)-nuatigenin and (25S)-isonuatigenin ...
    • Costunolide and Flavonols from Gochnatia Foliosa Var. Fascicularis 
      Faini, Francesca; Castillo, Mariano; Torres, René (1984)
      As part of a systematic chemical investigation of Chilean Compositae (1-3), we examined the secondar chemistry of a member of the genus Gochnatia (tribe Mutisieae, subtribe Gochnatiinae): Gochnatia foliosa var. fscicularia ...

      Faini, Francesca; Labbé, Cecilia; Torres, René; Delle Monache, Franco; Delle Monache, Giuliano (1999)
      Three new diterpenes were isolated from the aerial part of Haplopappus chrysanthemifolius and assigned the structures 6α-hydroxy-ent-labd-8(17)-en- 15-oic acid, 3β-acetoxy-ent-labd-8(17)-en-15-oic acid and 18α-acetoxylabd- ...

      The in vitro effect of the resinous exudate of Heliotropium filifolium, of the 3 H-spiro[1-benzofuran-2,1'-cyclohexane] derivative called filifolinol 1, isolated from the resin and the semi-synthetic compounds filifolinone ...
    • New phenolic esters from the resinous exudate of Haplopappus taeda 
      Faini, Francesca; Labbé, Cecilia; Torres, René; Rodilla, Jesús M.; Silva, Lucía; Monache, Franco Delle (2007)
      Two new phenolic esters 9-trans-p-coumaroyloxy-α-terpineol (1) and 7-trans-p-coumaroyloxy-taedol (2), both endowed with free radical scavenger activity and cleroda-3,13 (E)-dien-15,18-diol (3) for which a cis stereochemistry ...
    • Two new O-geranyl coumarins from the resinous exudate of Haplopappus multifolius
