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.

What's We Know About Brucine




Product name:Brucine
CAS:357-57-3
Molecular Formula:C23H26N2O4
Molecular Weight: 394.46g/mol
Description of Brucine:
Synonyms:Strychnidin-10-one, 2,3-dimethoxy-;(-)-Brucine;Brucine alkaloid;Brucin;Brucina;Dimethoxy strychnine;2,3-Dimethoxy-strychnine;10,11-Dimethystrychnine;Rcra waste number P018;Strychnine, 2,3-dimethoxy-;UN 1570;10,11-Dimethoxystrychnine;2,3-Dimethoxystrychnidine-10-one;2,3-Dimethoxystrychnidin-10-one
Appearance:  white crystalline powder
Melting Point:  177 C
Water Solubility:  slight
Stability:  Stable. Combustible. Incompatible with strong oxidizing agents.
Brucine is a bitter alkaloid closely related to strychnine. It occurs in several plant species, the most well known being the Strychnos nux-vomica tree, found in South-East Asia.
While brucine is related to strychnine, it is not as poisonous. Nevertheless, a human consuming over 2 mg of pure brucine will almost certainly suffer symptoms resembling strychnine poisoning (LD50 (rats, oral) 1 mg/kg, LD50 (rabbit, oral) 4 mg/kg). The probable fatal dose in adults is estimated at 1 gram.Another source gives the minimal lethal dose in humans as 30 mg.

Export High Quality Rutin




Product name:Rutin
CAS:153-18-4
Molecular Formula:C27H30O16
Molecular Weight: 610.52g/mol
Description of Rutin:
Rutin belongs to a class of plant secondary metabolites called flavonoids that are also known as rutoside, sophorin and quercetin-3-rutinoside. Rutin is a bioflavonoid, at times mentioned as vitamin P, which comprises citron, hesperidin and eriodictyl and is essential for assimilating vitamin C. In fact, bioflavonoids, such as quercetin and hesperidin, are quite identical to the composition of rutin and, hence, several experts agree that rutin and quercetin actually work in tandem by harmonizing each other. Hence, it is suggested that rutin and quercetin are taken collectively. In fact, bioflavonoids are becoming increasingly popular owing to their high nutritional value and positive health value. Hence, it is not surprising that rutin is always present in extremely nourishing foods, for instance, red apples, broccoli, citrus, onions and even different teas. Rutin is normally available as a supplement and consumed easily. Since our bodies are unable to produce bioflavonoids, it is essential to include them in our diets in order to remain in the pink of health.
