Description: Natural tomato lycopene is a mixture of isomers, primarily (all-E), but also some (5-Z) and two lesser and unidentified cis isomers, all of which are difficult to resolve by LC. Lycopene is an open chain unsaturated carotenoid that gives tomatoes, guava, rose hip, watermelon and pink grapefruit its red color. Studies show that lycopene intake is significantly associated with lower risk of lung, colon and stomach carcinogenesis. It is an antioxidant.
Isolated from commercially-grown tomatoes (L. esculentum) and once recrystallized and hexane washed.
Antioxidant micronutrient of tomatoes associated with decreased risk for cancer and cardiovascular disease. Enhances gap junction communication between cells via upregulation of connexin 43 and reduces proliferation of cancer cells in culture. Inhibits cholesterol synthesis and enhances low-density lipoprotein degradation. In vitro, lycopene is a powerful carotenoid quencher of singlet oxygen, being 100 times more efficient in test tube studies of singlet-oxygen quenching action than vitamin E, which in turn has 125 times the quenching action of glutathione (water soluble). Lycopene metabolite apo-10'-lycopenal, or ALA, may have an important role in the metabolism of hepatic lipids, and may prevent build up.

Description: Bilirubin is the principal pigment of bile and constituent of many biliary calculi and also found in blood. As the major end-product of the biological breakdown of heme, bilirubin is the chromophore responsible for coloration in various forms of jaundice.
Bilirubin is suitable for use in the preparation of standard stock solutions of bilirubin for color density comparison in the determination of serum bilirubin.
It appears to function as an antioxidant and efficient peroxyl radical scavenger, protecting membrane lipids from oxidation by these radicals. At nanomolar concentrations it has been shown to protect neurons from oxidative damage.
Bilirubin is produced from Ox-gall which is sterilized before extraction with high pressure vapour at 120 °C. Then the bilirubin is extracted in a continuous extraction process with chloroform as a crude product. Recrystallization and purification is with ethanol and chloroform.
-20°C. Protect from light.

Supplier: Spectrum Chemicals
Description: Acetic Acid, Glacial, Reagent, ACS, also known under the name ethanoic acid, it is an organic compound and a colorless liquid. It has a distinctive sour taste and pungent smell. It is the main component of Vinegar after water (8% by volume). Classified as a weak Acid, when concentrated it is corrosive and can attack the skin. In its Glacial form (undiluted), it is used as a polar protic solvent. As a solvent it is used for purification by recrystallization of organic compounds and in the production of terephtalic acid. As an ACS grade Reagent, Spectrum Chemical manufactured Acetic Acid is used as the quality standard against which other substances are graded and has met the toughest regulatory standards for quality and purity
