Popis: | Anacardic acids synthesized from [1-14C] and [2-14C] acetates byGinkgo biloba were subjected to chemical degradation to locate the14C in the molecules. Radioactivity in the carboxyl group was determined by decarboxylation and counting the resulting CO2; in the aliphatic chian, by oxidation of anacardol from which three homologous fatty acids are obtained; and in ring C-6, chain C-1 and chain C-2 by decarboxylation of these fatty acids where the carboxyl groups represent these respective C atoms. Distribution of14C in the anacardic acids indicates that synthesis of the chain and of the ring are separate processes. According to its radioactivity, ring C-6 originates from the chain. A polyketide mechanism appears likely for the ring synthesis, although considerable randomization of 1-14C and of 2-14C from the acetates had occurred in the plants. |
