The aim of this study was to investigate and assess the effects of propolis flavonoids liposome imposed on the immune system by comparing it to propolis flavonoids and blank liposome. In vitro, the effects of the above drugs on macrophages were assessed by measuring the phagocytic function and cytokine production. In vivo, the immunological adjuvant activity of propolis flavonoids liposome was ...

reseda (tourn.) et l. is a genus inresedaceae family with 153 species and subspecies in the world and 14 species in iran. some flavonoid compounds have been reported from the reseda genus. flavonoids are as one set of the polyphenolic compounds among secondary metabolites in different organs of plants that are used in plant chemotaxonomy. they have basic role in pollination and life cycle of an...

There is increasing interest in the potential health benefits of dietary flavonoids. Fruits and vegetables, tea, and cocoa are rich natural sources of flavonoids. Epidemiological studies have indicated that consumption of these foods is likely to be associated with a reduced risk of cardiovascular disease, but the etiology of this benefit is not yet clearly defined. Furthermore, in some acute i...

In recent years, there is an increasing interest in antioxidants. The main reason for this interest is the protection of cells, their organelles (especially membranes) and metabolic pathways against oxygen free radicals and their reactive derivatives (ROS). They participate in formation of chronic inflammation states and other diseases associated with oxidative stress, such as cancer, hypertens...

It was hypothesized that 5,7,4'-OH-flavonoids disappeared more rapidly from human fecal incubations and were less absorbable by humans than flavonoids without 5-OH moieties. Anaerobic fecal disappearance rates over 24 h were determined for 15 flavonoids in samples from 20 men and 13 women. In these anaerobic fecal mixtures, flavonoids with 5,7,4'-OH groups, genistein, apigenin, naringenin, lute...

OBJECTIVE To determine the antitumor activity of Radix tetrastigmae flavonoids and their inhibitory effect on regulatory T cells (Tregs) in mice. MATERIALS AND METHODS Total flavonoids were isolated from Radix tetrastigmae, the root of Tetrastigma hemsleyanum Diels et Gilg, and administered to C57BL/6 mice by oral gavage after inoculation with Lewis lung carcinoma (LLC) cells. The effects of ...

Flavonoids and carotenoids with rich structural diversity are ubiquitously present in the plant kingdom. Flavonoids, and especially their glycosides, are more hydrophilic than most carotenoids. The interaction of flavonoids with carotenoids occurs accordingly at water/lipid interfaces and has been found important for the functions of flavonoids as antioxidants in the water phase and especially ...

Stress-responsive dihydroxy B-ring-substituted flavonoids have great potential to inhibit the generation of reactive oxygen species (ROS) and reduce the levels of ROS once they are formed, i.e., to perform antioxidant functions. These flavonoids are located within or in the proximity of centers of ROS generation in severely stressed plants. Efficient mechanisms have been recently identified for...

Flavonoids and their photochemical transformations play an important role in biological processes in nature. Synthetic photochemistry allows access to molecules that cannot be obtained via more conventional methods. This review covers all published synthetic photochemical transformations of the different classes of flavonoids. It is first comprehensive review on the photochemistry of flavonoids.

Larix gmelinii, Pinaceae, Flavonoids, High-Performance Liquid Chromatography From needles of Larix gmelinii sixteen flavonoids were isolated and identified. The main flavonoids had been analyzed before, eight minor ones were identified as quercetin-3-glucoside, isorhamnetin-3-glucoside and -3-arabinoside, a somewhat lipophilic kaempferol-3-glucoside derivative, apigenin-7-glucoside, laricitrin-...
