Application
β-Carotene has been used:
as standard for quantification of b-carotene using HPLC analysis
as a standard for the identification and quantification of authentic standards for carotenoid groups
for standard curve preparation in the measurement of β-carotene production
for standard curve preparation in nutritive assays

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.
