盾木酮類化合物是一類黃酮類衍生物，結構類型主要有黃烷醇型、黃酮醇型、二氫黃酮醇型及花色素型，主要分布在豆科云實亞科Umtiza屬、角刺豆屬、紫心蘇木屬、短蓋豆屬、儀花屬、粗豆樹屬、云實屬及兩蕊蘇木屬，含羞草亞科的金合歡屬，蝶形花亞科魚藤屬、雞血藤屬、灰毛豆屬中，零星分布在鳶尾科、蓼科、大戟科、衛(wèi)矛科、藍雪科、楝科、藤黃科、巖蕨科、箭蕨科等植物中，具有重要的植物化學分類學意義。綜述近年來分離得到的盾木酮類化合物的結構及其在植物界的分布情況，為其進一步研究提供依據(jù)。

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.
