C-黄酮苷 1. C-glycosides and phenolic acids in the extracts were analyzed qualitatively,and the contents of C-glycosides and phenolic acids in different eluent were quantified by detective high-performance liquid chromatography(HPLC ). 结果:在总提取物中检测到C-黄酮苷类和酚酸类两类生物活性的物质...
The antioxidant activity and radical-scavenging activity of flavonoids depend highly on their structure, especially the presence of a free C-3–OH, a free C-4–OH, a double bond between C-2 and C-3, and an O-dihydroxy group in the B-ring [31]. The isolated flavonoids were a good ...
Flavonoid 3′-hydroxylase (F3′H) and flavonoid 3′5′-hydroxylase (F3′5′H) are the enzymes that diverge the biosynthetic branch from dihydrokaempferol into dihydroquercetin and dihydromyricetin, leading to the generation of catechin compounds and quercetin/myricetin glycosides. For galloylated ...
The aim of this study was to evaluate the anti-inflammatory and hepatoprotective effects of the total flavonoid C-glycosides isolated from Abrus mollis extracts(AME).In the anti-inflammatory tests,xylene-induced ear edema model in mice and carrageenan-induced paw edema model in rats were applied....
In tea leaves, flavonols are mainly found as O-glycosides with a glycoside moiety located at the C-3 position of aglycones such as quercetin, kaempferol, and myricetin [5]. These flavonol glycosides are not only associated with tea flavor, but also have an influence on its coloration [6, ...
Three reference flavonoid C-glycosides including vicenin-2, isoschaftoside and schaftoside, were isolated from A. mollis in our lab and identified based on 1 H, 13 C NMR and MS spec- troscopy and comparisons with literature data [5,8]. The purity of each reference was determined to ...
Hepatitis C virus (HCV) infection is a major cause of chronic liver diseases that often requires liver transplantation. The standard therapies are limited by severe side effects, resistance development, high expense and in a substantial proportion of cases, fail to clear the infection which bespeak...
Motif 7 was the consensus PSPG-box present at the C-terminal of all AhUGTs. While motif 8, 9, 10, 11, and 12 occurred in most of AhUGTs, other motifs existed in specific groups. For instance, motif 3 was only found in group D, B and J, and motif 5 was uniquely present in ...
Icaritin and its glycosides enhance osteoblastic, but suppress osteoclastic, differentiation and activity in vitro Life Sci. (2007) S. Peng et al. The beneficial effect of icaritin on osteoporotic bone is dependent on the treatment initiation timing in adult ovariectomized rats Bone (2013) C.A. ...
Soybean seeds from the cultivars, Conrad, AC Colombe, AC Glengarry and Pagoda, were planted in Pro-Mix BX Mycorrhizae™ soil (Rivière-du-Loup, Canada) in a growth chamber with a 16 h light cycle at 25 °C, and an 8 h dark cycle at 20 °C, with 60-70% relative humidity, with...
