Flavonoid glucuronides

Scutellarin is a flavone, a type of phenolic chemical compound. It can be found in the Asian "barbed skullcap" Scutellaria barbata and the North American plant S. lateriflora both of which have been used in traditional medicine. The compound is found only in trace amounts in the "Chinese skullcap" Scutellaria baicalensis, another plant used in traditional Chinese medicine.

Baicalin is the glucuronide of the polyphenolic compound baicalein.

Miquelianin (quercetin 3-O-glucuronide) is a flavonol glucuronide, a type of phenolic compound present in wine, in species of St John's wort, like Hypericum hirsutum, in Nelumbo nucifera (Indian lotus) or in green beans.

Oroxindin is a flavone, a type of phenolic chemical compound. It is a wogonoside, more accurately a wogonin glucuronide isolated from Oroxylum indicum (Bignoniaceae), Bacopa monnieri (Plantaginaceae), and Holmskioldia sanguinea (Chinese hat plant, Verbenaceae).
