title: Beta-zeacarotene of the bovine ovary.
abstract: An investigation of the carotenoids from a bovine ovary extract has revealed the presence of three Porter-Lincoln pathway intermediates of which beta-zeacarotene is previously unreported. Analysis using spectrophotometric and chemical tests reveals beta-zeacarotene (2.14 micrograms/g), alpha-carotene (0.11 microgram/g), and beta-carotene (27 and 35 micrograms/g).
