[摘要]
盾木酮类化合物是一类黄酮类衍生物,结构类型主要有黄烷醇型、黄酮醇型、二氢黄酮醇型及花色素型,主要分布在豆科云实亚科Umtiza属、角刺豆属、紫心苏木属、短盖豆属、仪花属、粗豆树属、云实属及两蕊苏木属,含羞草亚科的金合欢属,蝶形花亚科鱼藤属、鸡血藤属、灰毛豆属中,零星分布在鸢尾科、蓼科、大戟科、卫矛科、蓝雪科、楝科、藤黄科、岩蕨科、箭蕨科等植物中,具有重要的植物化学分类学意义。综述近年来分离得到的盾木酮类化合物的结构及其在植物界的分布情况,为其进一步研究提供依据。

[Abstract]
Peltogynoids are derivants of flavonoids found in recent years. These compounds are mainly divided into the following types according to their chemical structures: flavanols, flavonols, flavanonols, and anthocyanosides. They are mostly distributed in Fabaceae such as Caesalpinioideae (genus Umtiza L., Goniorrhachis Taub., Peltogyne Vogel., Brachystegia Benth., Lysidice Hance., Trachylobium, Caesalpinia Linn., and Distemonanthus Benth.), Mimosoideae (genus Acacia Mill.), and Papilionideae (genus Derris Lour., Millettia Wight et Arn. and Tephrosia Pers.). They are also distributed sporadically in the family Iridaceae, Polygonaceae, Euphorbiaceae, Celastraceae, Plubaginaceae, Meliaceae, Clusiaceae, Woodsiaceae, and Ophioglossaceae. Because peltogynoids have limited distribution in plant kingdom, they have important chemotaxonomic significance. This paper reviewed in researches recent years on peltogynoids isolated from natural products and their distribution in plant kingdom, so as to provide scientific basis for further study.
