Pericarp disks from the fruit of the jackbean (Canavalia ensiformis) when exposed to (14)CO2 for 2 days carried out photosynthesis and the canavanine extracted from the tissue was labeled with the radioisotope. When beef liver arginase was allowed to react with this canavanine the products were homoserine, canaline, urea and an unknown compound. The activity ratio of C4:C1 compounds was close to 2:1. No label could be detected in the canavanine from leaves exposed in the same way to (14)CO2 and it was concluded that normally canavanine synthesis occurs in the pericarp chlorenchyma.
刀豆果皮组织在暴露于（14）CO2 下 2 天后，能够进行光合作用，并且从组织中提取的刀豆氨酸被放射性同位素标记。当牛肝精氨酸酶与这种刀豆氨酸反应时，产物是同型丝氨酸、瓜氨酸、尿素和一种未知化合物。C4：C1 化合物的活性比接近 2:1。用同样的方法暴露于（14）CO2 的叶片中的刀豆氨酸没有检测到标记，因此可以得出结论，刀豆氨酸的合成通常发生在果皮的绿薄壁组织中。
