Abstract The phytochemical information on Millettia dura Dunn, M. ferruginea (Hochst.) Baker and M. ferruginea subsp. darassana (Cufod.) J.B. Gillett was reviewed. All the three taxa elaborate mainly isoflavones (33 reported), occurring in the flowers, seeds/seed pods, stem bark and root bark. Out of the 33 isoflavones reported, some 19 (ca. 58%) contain prenyl at C-8 or its modification as 2,2-dimethylchromene ring at C-7/C-8, occurring in all the three taxa. Except for three isoflavones isolated from M. ferruginea subsp. darassana, all the isoflavones of these taxa are 5-deoxygenated. In these taxa, oxygenation at C-6 is a common feature, while isoflavones with C-8 oxygenation are rare, only three reported, and all of these from M. dura. There are 7 rotenoids reported from these taxa, and occur almost entirely in the seeds/seedpods of these plants. The major rotenoid with methylenedioxy group at C-2/C-3, millettone and its 12a-hydroxy derivative, millettosine, occur only in M. dura, this appears to distinguish M. dura from M. ferruginea.

Millettia dura 和 Millettia ferruginea 的类黄酮和异黄酮：植物化学评价和化学分类学价值

摘要 Millettia dura Dunn、M. ferruginea (Hochst.) Baker 和 M. ferruginea subsp. 的植物化学信息。darassana (Cufod.) JB Gillett 被审查。所有三个类群都主要合成异黄酮（33 个报道），存在于花、种子/种荚、茎皮和根皮中。在报告的 33 种异黄酮中，约有 19 种（约 58%）在 C-8 处含有异戊二烯或其修饰为 C-7/C-8 处的 2,2-二甲基色烯环，存在于所有三种分类群中。除了从 M. ferruginea subsp. 中分离出的三种异黄酮。darassana，这些分类群的所有异黄酮都是 5-脱氧的。在这些分类群中，C-6 的氧化是一个共同特征，而具有 C-8 氧化的异黄酮很少见，只有三个报道，并且所有这些都来自 M. dura。从这些分类群中报告了 7 种类胡萝卜素，并且几乎完全发生在这些植物的种子/种荚中。在 C-2/C-3 上具有亚甲二氧基的主要类胡萝卜素，小米酮及其 12a-羟基衍生物，小米酮苷，仅存在于硬脑膜中，这似乎是将硬脑膜与 M. ferruginea 区分开来。
