Seaweed Ceratophyllum submersum contains many bioactive ingredients, notably fucoidan. This study presents the effect of ultrasound on fucoidan content extracted from C. submersum seaweed. Raw fresh seaweed (collected in Soc Trang) is dried to the humidity below 10% and sieve through a 0.3mm sieve to uniformize the size. Investigating the effects of ultrasonic waves (capacity, time) on fucoidan extraction. The results showed that, the content of fucoidan at 30% capacity was liQ78.30 ± 6.75 pg / gck, higher than 20% (936.88 ± 6.19 pg / gck) and 40%. (880.54 ± 8.92 pg / gck). Ultrasound time of 8 minutes for fucoidan content reached 1393.64 ± 3.23 pg / gck. Optimizing the ultrasound process with a capacity of 32.6% in a time of 8.64 minutes for fucoidan content to reach 1040,573 pg / gck.
