Abstract:
The structures of three new compounds isolated from Peperomia proctorii, named proctoriones A-C, have been established by spectroscopic and chemical methods as 2,3-dihydro-5, 8-dihydroxy-2-pentadecyl-4H-benzopyran-4-one (1) and enolic forms of 4-hydroxy-2-octadecanoylcyclohexane-1,3-dione (2) and 4-hydroxy-2-octadec-(11Z)-enoylcyclohexane-1,3-dione (3).
