neo-Clerodane diterpenoids from Baccharis flabellata.
Three diterpenoid derivatives were isolated from the acetone extract of Baccharis flabellata. Their structures were elucidated as 2,19;15,16-diepoxy-neo-clerodan-3,13(16),14-trien-18-oic acid, 15,16-epoxy-5,10-seco-clerodan-1(10),2,4,13(16),14-pentaen-18,19-olide and 15,16-epoxy-neo-clerodan-1,3,13(16),14-tetraen-18,19-olide through spectroscopic analyses.
