摘要：

A study of the biosynthesis of 3-nitropropionic acid in Indigofera spicata (Jacq.) Forsk. was undertaken by feeding14C-labeled precursors to intact plants or to cuttings. An organic acid fraction containing 3-nitropropionic acid was obtained by extraction of the plant material and separation by column chromatography. The 3-nitropropionic acid and other major organic acids were separated and analyzed quantitatively by gas-liquid partition chromatography. No evidence was obtained to suggest that Krebs cycle acids were precursors of 3-nitropropionic acid. Malonic acid or a derivative of malonate appears to be a fairly immediate precursor since14C was found in 3-nitropropionic acid when malonate-2-14C or malonyl itionohydroxamate- 2-14C were fed as precursors. © 1969, American Chemical Society.
