What's We Know About Aesculetin
Product name:Aesculetin
CAS:305-01-1
Molecular Formula:C9H6O4
Molecular Weight: 178.14g/mol
Description of Aesculetin:
Aesculetin (also known as esculetin, 6,7-dihydroxycoumarin and cichorigenin) is a derivative of coumarin. It is a natural lactone that derives from the intramolecular cyclization of a cinnamic acid derivative.
It is present in many toxic and medicinal plants, in form of glycosides and caffeic acid conjugates.
Esculetin-containing preparations used systemically can have an anticoagulant effect and might interact with anticoagulent drugs such as warfarin.
This compound is used in some sunscreens, but there is evidence that it acts as a photosensitizer for DNA damage.The sodium salt of its methyl-derivative is used in dermatology for the treatment of varicose veins.

Sell Apigenin at Competitive Price
Product name: Apigenin
CAS:520-36-5
Molecular Formula:C15H10O5
Molecular Weight: 270.24g/mol
Description of Apigenin:
Apigenin is an antioxidant plant flavanoid which contains anti-inflammatory and anticancer properties. It may induce apoptosis and may inhibit proliferation of tumor cells by arresting the cell cycle at the G2/M phase. Is also known to be a MAP kinase inhibitor and a selective inhibitor of Protein Kinase 2 (CK2). Apigenin is capable of exerting diverse effects on a vast variety of molecular targets. Most effects appear to be mostly mediated through suppressing nitric oxide synthase-2 (NOS2), Hypoxia-inducible factor 1 alpha (HIF-1α), lipoxygenase, cyclooxygenase-2 (COX-2) and vascular endothelial growth factor (VEGF) expression. Blocks proliferation of Wnt-1 transfected cells, dephosphorylates beta-catenin and lowers levels of beta-catenin and Dvi.

Aescine Sodium Information
Product name:Aescine Sodium
CAS:20977-05-03
Molecular Formula:C55H85NaO24
Molecular Weight: 1153.2g/mol
Description of Aescine Sodium:
Specifications: ≥97%
Ingredients: Aescigenin
Characteristics: white or off-white powder, bitter, dissolve in water, methanol, ethanol, and butanol, unsoluble in chloroform and acetic acid.
Indications:
Aescigenin has been shown to promote circulation through the veins. Aescigenin fosters normal tone in the walls of the veins, thereby promoting return of blood to the heart.
This has made both topical and internal horse chestnut extracts popular in Europe for the treatment of chronic venous insufficiency and, to a lesser extent, varicose veins. Aescigenin also possesses ant-iinflammatory properties and has been shown to reduce edema (swelling with fluid) following trauma, particularly following sports injury, surgery, and head injury.

What is Luteolin
Product name:Luteolin
CAS:491-70-3
Molecular Formula:C15H10O6
Molecular Weight:286.24 g/mol
Description of Luteolin:
Luteolin is a yellow crystalline compound. It is a flavonoid; to be specific, it is one of the more common flavones. From preliminary research, it is thought to play a role in the human body possibly as an antioxidant, a free radical scavenger, a promoter of carbohydrate metabolism, or an immune system modulator. If applicable to the human condition, these characteristics may inhibit cancer mechanisms. Basic research results indicate luteolin as an anti-inflammatory agent with other potential effects on septic shock. It has been suggested for multiple sclerosis on the basis of in vitro work.
Luteolin is most often found in leaves, but it is also seen in celery, thyme, dandelion, rinds, barks, clover blossom, and ragweed pollen. It has also been isolated from Salvia tomentosa. Dietary sources include celery, green pepper, thyme, perilla, chamomile tea, carrots, olive oil, peppermint, rosemary, navel oranges, and oregano.
