The biosynthetic pathway of capsinoid in ‘CH-19 Sweet’ was investigated. [³H]Valine and [¹⁴C]phenylalanine were injected into the fruits of the intact plant. Both of radioactivities were detected in capsinoid fractions. ¹⁴C radioactivity was observed in phenylpropanoid compounds, and in vanillin, vanillylamine, vanillyl alcohol, and vanillic acid. We confirmed that capsinoid is biosynthesized from phenylalanine and valine.
