Application

Beta Carotene USP Reference standard, intended for use in specified quality tests and assays as specified in the USP compendia. Also, for use with USP monographs such as:
  • Beta Carotene Capsules
  • Beta Carotene Preparation
  • Carotenes
  • Oil-Soluble Vitamins Oral Solution
  • Spirulina Tablets
  • Spirulina
  • Oil-Soluble Vitamins with Minerals Oral Solution

Biochem/physiol Actions

The most important of the provitamins A, β-carotene can be classified as an antioxidant due to its inhibition of radical initiated peroxidation in vitro. However, in vivo it appears to act either as an antioxidant or a prooxidant depending on cellular environment. It reduces the incidence of many cancers, but enhances lung cancer incidence in smokers.

Currently, on an industrial scale, synthetic colorants are used in many fields, as well as those extracted with conventional organic solvents (COSs), leading to several environmental issues. Therefore, we developed a sustainable extraction and purification method mediated by ionic liquids
