Three growth inhibitors which might be involved in phototropism of Sakurajima radish (Raphanus sativus var. hortensis f. gigantissimus Makino) hypocotyls, were isolated as crystalline forms from light-exposed radish seedlings and identified as cis- and trans-raphanusanins and 6-methoxy-2,3,4,5-tetrahydro-1,3-oxazepin-2-one (designated raphanusamide). The cis- and trans-raphanusanins inhibited growth of etiolated radish hypocotyls at concentrations higher than 1.5 micromolar, raphanusamide at concentrations higher than 20 micromolar.
从暴露在光线下的萝卜幼苗中分离出三种可能参与樱岛萝卜(Raphanus sativus var. hortensis f. gigantissimus Makino)下胚轴向光性的生长抑制剂,它们以结晶形式存在,并被鉴定为顺式和反式莱菔硫烷以及 6-甲氧基-2,3,4,5-四氢-1,3-恶唑-2-酮(命名为莱菔酰胺)。顺式和反式莱菔硫烷在浓度高于 1.5 微摩尔时抑制黄化萝卜下胚轴的生长,莱菔酰胺在浓度高于 20 微摩尔时抑制生长。
