摘要：

A procedure was devised to determine cis- and trans-aconitate in plant materials through conventional polarography. The procedure minimizes both nonenzymatic aconitate isomerization and sample cleanup and manipulation. Variations in recovery of cis- and trans-aconitates added at known levels were within instrumental error. The trans-aconitate levels determined compared favorably with analyses by silica gel column chromatography, in tests with low-cis-aconitate plant materials. A discrepancy in high-cis-aconitate plants appeared to be due to enhanced isomerization rates in the chromatographic process. The procedure was applied to show variations in plant aconitate with time, species, plant part, and anatomical location. © 1969, American Chemical Society. All rights reserved.
