%X Samples of Eisenia arb車rea from Baja California Sur, M谷xico collected in November 2002 and March 2003 were studied. The following parameters were analyzed separately from blades and stipes: moisture, ash, mannitol, fat and crude fiber. Alginate was isolated and the following quality parameters were obtained: yield (22.4-23.3%), color (> 4) and viscosity (793- 2,210 m-Pa-s in 1% solution). No significant differences were obtained between two months, except for viscosity and crude fiber. Significant differences were obtained when comparing blades and stipes in viscosity, mannitol, ash and fat, while for yield, moisture and crude fiber no significant differences were obtained. FTIR spectroscopy showed that alginate from E. arb車rea contained similar amounts of mannuroic and guluronic acids (M/G = 1) Se estudiaron muestras de Eisenia arb車rea de Baja California Sur, M谷xico, recolectadas en noviembre de 2002 y marzo de 2003. Se determinaron los siguientes par芍metros en l芍mina y estipe: humedad, cenizas, manitol, grasas y fibra cruda. Se aisl車 el alginato y se obtuvieron los siguientes par芍metros: rendimiento (22,4-23,3%), color (> 4) y viscosidad (793-2.210 m-Pa-s en una soluci車n al 1%). No se encontraron diferencias significativas entre los dos meses, a excepci車n de la viscosidad y fibra cruda. Se obtuvieron diferencias significativas al comparar los resultados entre l芍mina y estipe en viscosidad, manitol, cenizas y grasas, mientras que en el rendimiento, humedad y fibra cruda no hubo diferencia significativa. El espectro FTIR mostr車 que los alginatos de E. arb車rea conten赤an una cantidad similar de 芍cidos manur車nico y gulur車nico (M/G = 1)
