LIMONOIDS FROM TIMBER OF TRICHILIA HEUDELOTTII PLANCH EX OLIV

Extraction of the timber of Trichilia heudelottii gave a series of esters of an oxidised triterpene alcohol with formic, acetic, and 2-methylbutyric acids and with unidentified hydroxy-acids. These are referred to as heudelottins. The parent alcohol has been assigned the structure 14β,15β-epoxy- 7α,11β,12α-trihydroxy-3-oxomeliac-1-ene. The name is based on the furyl cyclopentanophenanthrene meliacan, which is the parent of a number of limonoid triterpenes.
