Polymethoxylated flavonoids from Citrus reticulata Blanco
Biochemical Systematics and Ecology, 2016Abstract A new glycoside of polymethoxylated flavonol, citrusunshitin A (1), together with five known analogues (2–6) were isolated from peels of Citrus reticulata Blanco. The structure of 1 was elucidated by NMR and MS data, and further confirmed by single-crystal X-ray diffraction. Compounds 1–5 were isolated from C. reticulata Blanco.

Biosynthesis of citrus flavonoids and their health effects
Critical Reviews in Food Science and Nutrition, 2018Citrus-derived flavonoids play important roles in the regulation of physiological conditions of citrus plants, including color changes of flower and fruit, flavor development, and anti-stress physiology. Moreover, citrus flavonoids possess multiple health-promoting effects in humans, and they are important ingredients for nutraceuticals and functional ...

The use of citrus flavonoids in infections. II
The American Journal of Digestive Diseases, 1955In 69 cases of acute respiratory infections (of which23 have previously been reported), including the common cold, acute follicular tonsillitis and influenza, oral therapy with the whole water soluble citrus flavonoid complex (vitamin “P” complex) led to rapid subsidence of the infection usually in from 8 to 48 hours, occasionally somewhat longer ...

Flavonoid Composition of Fruit Tissues of Citrus Species
Bioscience, Biotechnology, and Biochemistry, 2006An HPLC analysis was performed on the concentrations of flavonoids in 42 species and cultivars of the Citrus genus and those of two Fortunella and one Poncirus species according to the classification system established by Tanaka. The composition of 8 flavanones and 9 flavone/ols for these species was determined in the albedo, flavedo, segment epidermis

Quantitation of Flavonoid Constituents in Citrus Fruits
Journal of Agricultural and Food Chemistry, 1999Twenty-four flavonoids have been determined in 66 Citrus species and near-citrus relatives, grown in the same field and year, by means of reversed phase high-performance liquid chromatography analysis. Statistical methods have been applied to find relations among the species.

Citrus flavonoid naringenin inhibits TLR2 expression in adipocytes
The Journal of Nutritional Biochemistry, 2013Toll-like receptors (TLRs) were recently shown to be involved in obesity-induced inflammation in adipose tissue, which contributes to the development of insulin resistance and type 2 diabetes. Thus, the appropriate regulation of TLR expression or activation is an important strategy for improving obesity-related diseases.

Nobiletin: a citrus flavonoid displaying potent physiological activity
Acta Crystallographica Section C Structural Chemistry, 2016Nobiletin [systematic name: 2-(3,4-dimethoxyphenyl)-5,6,7,8-tetramethoxy-4H-chromen-4-one; C21H22O8] is a flavonoid found in citrus peels, and has been reported to show a wide range of physiological properties, including anti-inflammatory, anticancer and antidementia activities. We have solved the crystal structure of nobiletin, which revealed that the

Antioxidant Activity of Citrus Limonoids, Flavonoids, and Coumarins
Journal of Agricultural and Food Chemistry, 2005A variety of in vitro models such as beta-carotene-linoleic acid, 1,1-diphenyl-2-picryl hydrazyl (DPPH), superoxide, and hamster low-density lipoprotein (LDL) were used to measure the antioxidant activity of 11 citrus bioactive compounds. The compounds tested included two limonoids, limonin (Lim) and limonin 17-beta-D-glucopyranoside (LG); eight ...

Citrus Flavonoid Complex: Chemical Fractionation and Biological Activity
Science, 1963A study was made of the anti-inflammatory activity of the fractionated components of a citrus flavonoid complex. Several highly active components, distinct from hesperidin and naringin, were isolated and tested for anti-inflammatory activity. A method for evaluation of this biological activity is recommended.
