Capillary electrophoresis was found to give significantly higher efficiency, selectivity and speed than high-performance liquid chromatography for the separation of a mixture of flavonoid-3-O-glycosides differing in their sugar moiety. Boric acid running buffer (0.2 M, pH 10.5) was used for this ...
1) flavonoid glycosides 黄酮苷类化合物1. A high performance liquid chromatography-electrospray ionization mass spectrometric method was developed for analysis and identification of flavonoid glycosides extracts from Fructus aurantii. 利用高效液相色谱与电喷雾质谱联用技术研究了枳壳中的黄酮苷类化合物。
Citrus fruit and juices are reported to have diverse methoxyflavonoids, such as hesperetin, isosakuranetin, chrysoeriol, and nobiletin, and their respective glycosides [19,20,21]. To identify functional FOMTs, orange (C. sinensis) OMT genes (CsOMTs) were retrieved from the Citrus Genome Data...
In food, flavonoids exist primarily as 3-O-glycosides and polymers [2]. Several types of higher structure exist, and polymers comprise a substantial fraction of dietary flavonoid intake [33]. Enzymatic oxidation of green tea leaves (Camellia sinensis) during fermentation to black tea results in ...

Data are presented as mean values ± SD (n = 3 biologically independent samples) (3a and c). The source data underlying Fig. (3a and c) are provided in a Source Data file. Full size image GuApiGT mainly catalyzed the apiosylation of flavonoid 7- or 4′-O-glycosides. The...
The extraction and solvent partition of the leaves of Eucalyptus citriodora , and repeated column chromatography for n -BuOH fraction yielded a new flavonoid glycoside, citrioside C ( 1 ), along with three known flavonoid glycosides ( 2–4 ). The latter were identified with kaempferol-3- O -...
AIM FiveIsoflavonoid glycosideswere isolated from the pericarps of Sophora japonica L. 方法:采用波谱和化学方法对 6 6个异黄酮甙类成分进行了鉴定。 更多例句>> 2) Isoflavone aglycones 异黄酮甙元 例句>> 3) isoflavone glycosides 异黄酮糖甙
Flavonoids generally occur as O-glycosides with sugars bound in nature, while aglycones and their derivatives are the main flavonoids in propolis. The objective of this work was to study the propolis β-glycosidase activities toward flavonoid β-glycosides and their conjugated forms. β-Glycosidase ...
