Abstract

<abstract abstract-type="main"> <title>Abstract</title> <sec id="jsfa5955-sec-0001" sec-type="section"> <title>BACKGROUND</title> <p> <bold> <italic>Jatropha cordata</italic> and <italic>Jatropha cardiophylla</italic> are native to northwestern Mexico and are adapted to arid and semi‐arid conditions (<500 mm of precipitation and temperatures from 8 to 45 °C). The aim of this study was to evaluate the chemical composition of <italic>J. cordata</italic> and <italic>J. cardiophylla</italic> kernels and oils as well as antinutrients in the defatted kernel meals of these species.</bold> </p> </sec> <sec id="jsfa5955-sec-0002" sec-type="section"> <title>RESULTS</title> <p> <bold>Kernels of <italic>J. cordata</italic> and <italic>J. cardiophylla</italic> seeds analysed in this study were rich in crude protein (283 and 289 g kg<sup>−1</sup> respectively) and lipid (517 and 537 g kg<sup>−1</sup> respectively). The main fatty acids in <italic>J. cordata</italic> and <italic>J. cardiophylla</italic> oils were linoleic and oleic acids. High levels of trypsin inhibitor and phytates and low levels of saponins were present in the meals. The phorbol ester contents in <italic>J. cordata</italic> and <italic>J. cardiophylla</italic> kernel meals were 2.73 and 1.46 mg g<sup>−1</sup> respectively.</bold> </p> </sec> <sec id="jsfa5955-sec-0003" sec-type="section"> <title>CONCLUSION</title> <p> <bold>For both <italic>J. cordata</italic> and <italic>J. cardiophylla</italic> it could be inferred that (a) the oil and kernel meal were toxic and the kernel meal could be used as livestock feed only after detoxification, (b) the oil could be used for non‐alimentary purposes, i.e. biodiesel production, and (c) the seed or oil could be used for isolating various bioactive compounds for pharmaceutical and agricultural applications. © 2012 Society of Chemical Industry</bold> </p> </sec> </abstract>
