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.
研究了'CH-19 甜'中
辣椒碱的
生物合成途径。将[3H]丙
氨酸和[14C]苯丙
氨酸注入完整植株的果实中。在蒴果苷馏分中检测到了这两种放射性物质。在苯丙类化合物、
香兰素、
香草醛、
香草醇和
香草酸中也观察到了 14C 放射性。我们证实蒴果苷是由苯丙
