Embodiment 1
[0038] The method for comprehensively extracting polyunsaturated fatty acids and polysaccharides from seaweeds of the present invention comprises the following steps:
[0039] Polyunsaturated fatty acid extraction:
[0040] A. Soak Sargasso algae in tap water equivalent to 20 times its weight for 5 minutes, then wash once with tap water and deionized water, and then bake at 80°C for 10 hours; after drying, crush it into 10-mesh Sargassum powder, Disperse Sargassum powder in petroleum ether according to the ratio of material to liquid at 1:5, and perform ultrasonic crushing. The ultrasonic power is 60W, the crushing time is 5min, and the temperature is maintained at 80°C during crushing;
[0041] B. The suspension after ultrasonic crushing is subjected to solid-liquid separation, and petroleum ether is added to the separated liquid as an extraction solvent, so that the solid-liquid ratio of seaweed powder and extraction solvent is 1:5, and the extraction solvent and solid resid...
