Phytoalexins have been defined as compounds formed or activated in a living plant cell in contact with fungi, which are antifungal and thereby prevent the full development of the incipient disease.Elicitors are considered to be agents which cause the accumulation of phytoalexins in higher plants. While various exogenous elicitors have been known, there are few reports of exact isolation of an endogenous elicitor, which has been deduced to exist in plants. We could indicate that hydrogen peroxide is a general and direct trigger substance for phytoalexin production and would activate or increase the presumable endogenous elicitor. These characteristics of hydrogen peroxide were found with potato, sweet potato, kidney bean, and sugar beet. Next, we have attempted isolation of an endogenous elicitor, which increases in potato tissues in contact with hydrogen peroxide. At the present stage, we could refine a compound having the elicitor activity in an almost pure state.

植物抗菌素被定义为在与真菌接触的活植物细胞中形成或激活的化合物，这些化合物具有抗真菌作用，从而防止早期疾病的全面发展。激发子被认为是高等植物中引起植物抗毒素积累的因子。虽然已知各种外源激发子，但很少有报道确切分离出内源激发子，它已被推断存在于植物中。我们可以表明过氧化氢是植物抗毒素产生的一般和直接触发物质，并会激活或增加可能的内源性激发子。过氧化氢的这些特性在马铃薯、甘薯、芸豆和甜菜中都有发现。接下来，我们尝试分离一种内源性激发子，它在与过氧化氢接触的马铃薯组织中增加。在目前阶段，我们可以在几乎纯净的状态下提炼出具有激发子活性的化合物。
