TL;DR: Evaluation of data reveals a correlation in most cases between the occurrence of flavonoid aglycones, the presence of secretory structures and the production of other lipophilic plant products.
319 citations
TL;DR: The biogenesis, structural diversity and distribution of simple, furano- and pyranocoumarins in the Rutaceae is reviewed and the potential value of these compounds as taxonomic markers and their possible functions are discussed.

TL;DR: The major polymethoxyflavones in the fruit (ponkan) peels of Citrus reticulata Blanco cv. ponkan were identified as isosinensetin, sinensetIN, nobiletin and tetramethyl-o-scutellarein by a combined separation using high-speed countercurrent chromatography and preparative high performance liquid chromatography, and structure elucidation by electrospray ionisation mass spectrometry (ESI-MS) and 1H and 13C nuclear magnetic resonance

TL;DR: 7-hydroxycoumarin [umbelliferone, (2)], one of the most widely distributed coumarins, is often regarded as the parent, in a structural sense and also biogenetically, of a large number of the structurally more complex coumarin.
Abstract: Over the past 150 years, since Vogel in 1820 isolated the parent oxygen heterocycle, coumarin (1) from Coumarouna odorata = Dipteryx odorata (1), coumarins have been recognized as widely distributed plant products. The vast majority carry an oxygen substituent at C-7; consequently 7-hydroxycoumarin [umbelliferone, (2)], one of the most widely distributed coumarins, is often regarded as the parent, in a structural sense and also biogenetically, of a large number of the structurally more complex coumarins. A number of review articles on natural plant coumarins have appeared (154, 302, 344, 420, 525, 541, 548) since the last in this series (153), the most comprehensive, albeit dealing solely with coumarins of the Umbelliferae, being that of Nielsen in 1970 (419).
