黄烷酮类植物抗毒素的研究简介

Research advances on flavanone phytoalexins

植物抗毒素是植物受到外界病原微生物侵扰后所产生并积累的一类具有抗菌活性的小分子物质,樱花素是从水稻稻瘟病感染组织中分离鉴定的一种黄烷酮类植物抗毒素.对以樱花素为代表的水稻抗毒素及其类似物的结构与活性、黄烷酮类植物抗毒素合成方法的研究概况进行了综述.

Phytoalexins are low molecular weight chemicals that plants produce and accumulate in response to infection especially of fungal origin. Sakuranetin is a kind of flavanone phytoalexin isolated from ultravioletirradiated rice leaves. Recent research work on flavanone phytoalexins represented by sakuranetin is reviewed. Interesting novel structures, stuctureactivity relationships and synthetic methods are discussed.
