Taurine is absent from amino components in fruits of Opuntia ficus-indica

Abstract

Abstract Juices of edible fruits from Opuntia ficus-indica (L.) Miller, commonly named prickly pears or Indian figs, were analysed for amino acids using an automated amino acid analyser run in the high-resolution physiological mode. Emphasis was put on the detection of free taurine (Tau), but Tau could be detected neither in different cultivars of prickly pears from Italy, South Africa and the Near East nor in commercially available prickly pear juices from the market.
