摘要

黄酮是一种非常简单的未取代类黄酮，在植物界的分布很有限。长期以来，人们一直知道它是许多报春花和洋二仙草腺毛分泌物的主要成分，其数量异常巨大，通常作为植物气生部分上的一种远志糖（蚧壳虫）沉积物。人们对这种独特的粉糖沉积物及其主要化合物黄酮的生态功能仍不甚了解。关于黄酮，与迄今已知的所有类黄酮生物合成途径相比，其生物合成起源仍是一个知识空白。因此，这篇综述不仅探讨了这种化合物的历史及其在植物中的存在及其各自的组成部分，而且还讨论了有关其推测生物合成的观点。此外，我们还全面提供了关于这种来自天然来源而非化学合成的化合物的最新分析数据。生态功能方面对这项研究进行了补充，旨在对未来的生态学和进化研究产生极大的推动作用。

Flavone From Plants—Uncommonly Common? A Comprehensive Review

Flavone is a very simple and unsubstituted flavonoid of restricted distribution in the plant kingdom. Historically it is known for a long time as major constituent of many Primula and Dionysia exudates produced by glandular hairs in unusually large amounts, often as a farinose (mealy) deposit on aerial plant parts. The ecological function of this unique farinose deposit and its main compound flavone is still not really understood. Concerning flavone, a knowledge gap exists about its biosynthetic origin, when compared to all of the flavonoid biosynthetic routes known to date. Thus, this review addresses not only the history of this compound and its occurrence in plants and in their respective compartments, but also discusses ideas on its putative biosynthesis. Furthermore, we provide up-to-date analytical data on this compound from a natural source, rather than from chemosynthesis, in a comprehensive way. Eco-functional aspects complement this study that is intended to be highly stimulating for future research in ecology and evolution.
