- W2284725507 abstract "Publisher Summary Most of the systems used for study of carotenogenesis are deficient in either yield of β-carotene or incorporation of label. This chapter discusses method for the preparation of 14 C-β-carotene. It is found that multiple crystallization gives higher yield and greater purity than any other method. Evaporate the chromatographic fraction to dryness in vacuum and redissolve in a minimum volume of boiling hexane, about 1 ml of hexane per milligram of carotene. The minimum volume can be determined by removing hexane vapors with a stream of nitrogen while warming the flask in a water or steam bath until an insoluble ring of carotene begins to form. Specific activity can be conveniently determined by measuring the amount of β-carotene spectrophotometrically and counting a known amount in suitable 14 C counting systems. Spectrophotometric determination in hexane at 450 nm using an absorption coefficient of 0.250 mg per liter gives excellent agreement with gravimetric determination." @default.
