Flavone glucosides

Vitexin is an apigenin flavone glucoside, a chemical compound found in the passion flower, Vitex agnus-castus (chaste tree or chasteberry), in the Phyllostachys nigra bamboo leaves, in the pearl millet (Pennisetum millet), and in Hawthorn.

Orientin is a flavone, a chemical flavonoid-like compound. It is the 8-C glucoside of luteolin.

Tetuin is the name originally allocated to a chemical constituent of the seeds of Oroxylum indicum, the Indian trumpetflower, known as टेटु tetu in Marathi. The original authors identified this chemical as the 6-O-glucoside of baicalein, a flavone, a type of flavonoid. Their identification was probably incorrect, as subsequent authors were able to demonstrate that baicalein 6-O-glucoside has different properties to the original tetuin from O. indicum seeds, and were unable to find baicalein glycosides in the seeds. Nevertheless, modern authors have used the name tetuin as a trivial name for ba

Apigetrin is a chemical compound that can be found in dandelion coffee and in Teucrium gnaphalodes.

Isovitexin (homovitexin or saponaretin) is a flavonoid, namely the apigenin-6-C-glucoside. In this case, the prefix 'iso' does not imply an isoflavonoid (the position of the B-ring on the C-ring), but the position of the glucoside on the flavone, in comparison to vitexin.

Cynaroside (also known as luteoloside) is a flavone, a flavonoid-like chemical compound. It is a 7-O-glucoside of luteolin.

Saponarin is a flavone glucoside. It is found in Saponaria officinalis and in Strongylodon macrobotrys where it imparts the characteristic jade color to the flower. This coloration has been shown to be an example of copigmentation, a result of the presence of malvin (an anthocyanin) and saponarin in the ratio 1:9. Under the alkaline conditions (pH 7.9) found in the sap of the epidermal cells, this combination produced a blue-green pigmentation; the pH of the colorless inner floral tissue was found to be lower, at pH 5.6. Experiments showed that saponarin produced a strong yellow colo

Isoorientin (homoorientin) is a flavone, a chemical flavonoid-like compound. It is the luteolin-6-C-glucoside.
