Flavonoids are a group of low–molecular-weight polyphenolic compounds. There are more than 6000 naturally occurring flavonoids, many of which are common in higher plants ( Harborne and Williams, 2000 ). The basic structure of flavonoids consists
primarily produced in leaves, among which flavonoids constitute a class of important compounds in herbal medicine ( Guo et al., 2020 ). Flavonoids are the major active secondary metabolites in the leaves of L. polystachyus ( Li et al., 2008 ). The many
species are rich in physiologically active flavonoids that have a wide spectrum of pharmacological activity. The medicinally significant part of the plant is species dependent.
Leaf extracts of Scutellaria barbata , also known as “Ban Zhi Lian
understanding genetic mechanisms of its petal coloration is a key to successful breeding. Flower coloration is due to the accumulation of pigments within epidermal cells, including flavonoids, which include chalcones, anthoxanthins (flavones and flavonols), and

colors has become one of the main research directions of Magnolia specialists. Flavonoids are secondary metabolites of water-soluble aromatics, with a series of two benzene rings connected by a central three-carbon chain, C6-C3-C6 ( Zhao and Tao, 2015
Okinawa, has been used for hypertension, lung disease, and liver disease and underdeveloped children as a folk remedy ( Kan, 1986 ). One of the most active components in Anoectochilus was flavonoid ( Takatsuki et al., 1992 ). Many of flavonoid

-carotene content as in TAM Mild Habanero (TMH) ( Crosby et al., 2005 ). Because peppers can contain both capsaicinoids (capsaicin and DHC) and flavonoids (quercetin and luteolin), they provide a good model for examining the potential health benefits of these

Anthocyanins are the result of the flavonoid pathway, which also produces flavonoids and flavonols at higher points in the pathway. Regulation of the pathway
