The genus Iris consists of approximately 360 species and is distributed to Eurasia, North Africa, and North America. Belamcanda chinensis was incorporated into the genus Iris by APG III as Iris domestica. Iris species have also been cultivated as ornamentals since ancient times. Many flavonoids are isolated and identified from the flowers, leaves, and rhizomes. So far as we know, 6 anthocyanidins, 13 flavones, 20 flavonols, 20 C-glycosylflavones, 14 flavanones, 11 dihydroflavonols, 6 flavan and proanthocyanidins, and 85 isoflavonoids were reported as aglycones and glycosides. However, chalcones, dihydrochalcones, aurones, biflavonoids, and neoflavonoids are not found in the genus Iris. Fifteen xanthones that are related to flavonoids were also isolated from Iris species. In this review, we describe the flavonoids and xanthones that were isolated and characterized from Iris species. Moreover, their phytochemistry, contribution to the flower colors, relationships with taxonomy, and activities and functions are also discussed.

鸢尾属约有360种，分布于欧亚大陆，北非和北美。贝拉坎达中华草被APG III作为家鸢尾并入鸢尾属。自古以来，虹膜物种还被用作观赏植物。从花，叶和根茎中分离并鉴定出许多黄酮。据我们所知，据报道有6种花色素苷，13种黄酮，20种黄酮醇，20种C-糖基黄酮，14种黄烷酮，11种二氢黄酮醇，6种黄酮和原花色素，以及85种异黄酮类化合物为苷元和糖苷。但是，鸢尾属植物中没有发现查耳酮，二氢查耳酮，金酮，双黄酮类和新黄酮类。还从鸢尾属植物中分离了十五种与类黄酮有关的氧杂蒽酮。在这篇综述中，我们描述了从鸢尾花属植物中分离和表征的类黄酮和黄原酮。此外，还讨论了它们的植物化学，对花色的贡献，与分类学的关系以及活性和功能。
