SUMMARY The guluronate (G) content of alginate in the fronds of Laminaria japonica and Laminaria angustata , cultured in the laboratory from zoospore via gametophyte using PESI medium, was determined by the 1 H‐nuclear magnetic resonance spectroscopic method. The G content of alginates in young fronds cultured in various conditions were shown to exceed 55%. These values were remarkably higher than those in field kelp. The G content increased with extending culture period and at low temperature.
