On the basis of our findings that the germination of intact wheat seeds (with husks) belonging to dormancy varieties was restrained as compared with that of the dehusked seeds (grains), the germination inhibitors in the husks were explored. The water-soluble extracts from the husks were separated by the aid of inhibition assay experiments, resulting in the characterization of 2-phenylethyl alcohol
根据我们的发现,与脱壳种子(谷粒)相比,属于休眠品种的完整小麦种子(有壳)的发芽受到抑制,因此探索了壳中的发芽抑制剂。借助抑制试验实验分离了壳中的水溶性提取物,从而表征了2-苯乙醇1、4-乙烯基苯酚2及其2-甲氧基衍生物3和二氢actinidiolide 4。在水溶液中以500 ppm抑制发芽。相关的化合物1-苯乙醇5和四氢放线菌二醇6的活性与1和4相同,而在两种对映异构体和化合物4-6的DL-形式之间均未检测到明显的活性差异。在4与1以及4与3之间观察到明显的协同关系。
