مقايسه ميزان اسيد آلژنيك استحصال شده از جلبك هاي قهوه اي Sargassum illicifolium , Cystoseira indica و Nizimuddinia zanardini در سواحل چابهار

Comparison of extracted alginic acid in brown algaes; Sargassum illicifolium, Cystoseira indica & Nizintuddinia zanardini in the Oman sea (Chabahar)

This study was determined alginic acid in three species of brown seaweeds {Sargassum illicifolium, Cystoseira indica and Nizimuddinia zanardinii) during Autumn and Winter 1384. Seaweed samples were colected from sea beach and washed in fresh water and dried in the sun. So were under Formaldeid (0.5%) and Solphoric acid (0.2 N) Respectively (2,5 hours). Fainaly were under Alkaloid extraction by sodium carbonate (5%), that were obtined fluid after Alteration. The alginic acid resulted with chloridric acid (IN). The extraction yield of alginic acid in Autumn for Sargassum were 32.1±0.96 , Cystoseira 23.1±0.46 and nizimuddinia 28.3±0.61 percent , and in Winter for sargassum were 29±0.72 cystoseira 21.4±0.53 and nizimuddinia 24.3±0.32 percent. According to this results, One way ANOVA showed that average of Alginic acid were not similar and significant differences (P< 0.05) between species.
