Resumo: | The carotenoid composition of &lt;i&gt;Artemia&lt;/i&gt; cysts from 17 geographical strains was studied. All-&lt;i&gt;trans&lt;/i&gt;-canthaxanthins and &lt;i&gt;cis&lt;/i&gt;-canthaxanthins were quantitatively determined using a non-aqueous reversed phase chromatographic method. In dehydrated cysts, the average &lt;i&gt;cis&lt;/i&gt;- and &lt;i&gt;trans&lt;/i&gt;-canthaxanthin levels (+/- SD) were 152 +/- 52 and 134 +/- 42 µg/g, respectively (range 38-227 and 67-201µg/g). The corresponding concentrations in hydrated cysts were (&lt;i&gt;cis&lt;/i&gt;) 177 +/- 60 µg/g (range 47-271 µg/g) and (&lt;i&gt;trans&lt;/i&gt;) 112 +/- 35 µg/g (range 52-169 µg/g). The &lt;i&gt;cis/trans&lt;/i&gt; concentration ratios averaged 1.13 (range 0.57-1.47) and 1.60 (range 0.84-2.54) for dehydrated and hydrated cysts, respectively. Differences in total canthaxanthin content in &lt;i&gt;Artemia&lt;/i&gt; cysts may partly reflect environmental variability (e.g. algal supply), whereas the divergence in the relative abundance of &lt;i&gt;cis&lt;/i&gt;- and &lt;i&gt;trans&lt;/i&gt;-canthaxanthin may be associated with differences in some physical and biological characteristics of the cysts.
