Orientin

Description:

Orientin, with the CAS number 28608-75-5, is a flavonoid glycoside primarily found in various plants, particularly in the leaves of certain species like the common buckwheat and in some herbs. It is characterized by its yellowish color and is known for its antioxidant properties, which contribute to its potential health benefits. Orientin is soluble in water and exhibits a sweet taste due to its glycosidic structure. This compound is often studied for its pharmacological effects, including anti-inflammatory, anti-diabetic, and neuroprotective activities. Additionally, orientin may play a role in protecting cells from oxidative stress and has been investigated for its potential in promoting cardiovascular health. Its presence in dietary sources suggests that it may contribute to the overall health benefits associated with a plant-rich diet. As with many flavonoids, the bioavailability and efficacy of orientin can be influenced by various factors, including the method of extraction and the presence of other compounds in the source material.

Orientin

CAS: 28608-75-5

Orientin has various activities including anti-oxidant, anti-aging, anti-viral, anti-bacterial, anti-inflammation, vasodilatation and cardioprotective, antiadipogenesis, antinociceptive, radiation protective, neuroprotective, and antidepressant-like effects. Orientin protects H9c2 cardio-mytocytes against I/R-induced apoptosis by modulating the mPTP opening, and this role of orientin may involve the PI3K/Akt signaling pathway; it also can decrease C/EBPα and PPARγ protein expression level in 3T3-L1 cells.

Orientin

CAS: 28608-75-5

Orientin (Luteolin-8-C-glucoside) is a flavonoid that has been shown to have biological properties, such as anti-inflammatory and antioxidant activities, which may be due to its ability to inhibit toll-like receptor 4. Orientin is an effective inhibitor of the growth of Leishmania amazonensis in vitro. It also inhibits the growth of Candida glabrata, a fungus that causes oral thrush and other infections. Orientin has been shown to have high values in inflammatory bowel diseases (IBD).
