flavescent

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 ultraviolet - irradiated rice leaves . recent research work on flavanone phytoalexins represented by sakuranetin is reviewed . interesting novel structures , stucture - activity relationships and synthetic methods are discussed 植物抗毒素是植物受到外界病原微生物侵擾后所產生并積累的一類具有抗菌活性的小分子物質,櫻花素是從水稻稻瘟病感染組織中分離鑒定的一種黃烷酮類植物抗毒素.對以櫻花素為代表的水稻抗毒素及其類似物的結構與活性、黃烷酮類植物抗毒素合成方法的研究概況進行了綜述
