Extraction, purification, and characterization of polysaccharides from marine algae Gracilaria lemaneiformis with anti-tumor activity

Recently, rapid and effective extraction and purification methods have attracted considerable interest as alternative approaches to conventional methods. In this study, ultrasonic-microwave-assisted extraction (UMAE) was used to extract Gracilaria lemaneiformis polysaccharides, and the response surface methodology was used to determine the optimum extraction conditions. Subsequently, an aqueous two-phase system (ATPS) was applied to the...
