Supernatant solutions of jellyfish (Aurelia aurita and Nemopilema nomurai) suspensions are useful for the soilless culture of the common ice plant (Mesembryanthemum crystallinum L.）. The plants were cultivated using supernatant solutions of jellyfish suspensions concentrated by means of in-vacuo heating with a control of edible salt. The culture fluids were prepared by measuring electric conductivity so that concentrations provided a final NaCl concentration of 0.5 or 1 ％ （w/v）. After harvesting the common ice plants, they were weighed. Concentrations of inorganic anions, organic acids, and amino acids in the edible portion of the common ice plant were determined using capillary zone electrophoresis （CZE）. Concentrations of Ca, Fe, and Zn in the common ice plant were determined using inductively coupled plasma （ICP） emission spectroscopy. Results were analyzed statistically. Except for nitrate, citric acid, and metal concentrations, no significant differences in other results were observed among the different concentrations of NaCl, the two kinds of jellyfish, and edible salt.
