European journal of clinical nutrition, 1996 Beta-carotene has been shown to exhibit a good radical-trapping antioxidant activity in vitro. We were interested to see if dietary beta-carotene in combination with various intake levels for vitamin A would also inhibit lipid peroxidation.Sixty male Wistar rats received vitamin A (as retinyl palmitate) for 14 weeks in the diet (40,000, 4000 and 400 IU/

Abstract A body of factual information has accumulated during the past decade which, in general, supports or is compatible with the proposal of Porter and Lincoln on the mechanism of biosynthesis of carotenes. However, some information has been obtained which necessitates a revision in details of the proposed scheme.

Kuhn and Winterstein reported the isolation of 2,6-dimethylnaphthalene from the products of pyrolysis of carotenoid pigments. The production of alkyl derivatives of phenanthrene and chrysene by the same type of cyclization can readily be formulated.

Formation of Carotene in vitro
Nature, 1960RESULTS presented in this communication indicate that both β-hydroxy β-methylglutarate and mevalonate may be considered precursors of carotene formation in an in vitro extract obtained from mycelial mats of the mould Phycomyces blakesleeanus. This extract, capable of synthesizing carotene, can also be used for establishing the existence of a back ...

The safety of beta-carotene, a widely distributed food colorant was assessed in tests with cells and in sub-chronic and chronic experiments with animals. Mutagenicity evaluations which included the standard Ames test and the micro-nucleus test of bone marrow cells from mice showed that beta-carotene exerted no mutagenic properties.
