Ultrasonic Method on the Extraction of Fucoxanthin from Marine Macro Algae Padina Australis

Macro algae is the potential feedstock of fucoxanthin production. Fucoxanthin is a bioactive pigment found in the chloroplasts of marine algae and have a considerable pharmacological property. Fucoxanthin belongs to carotenoid which plays as an important ingredient in food and pharmaceutical industries. This study explains effect of ultrasonics on the extraction of fucoxanthin from marine macro algae Padina australis. Additionally, the effect of solvents and various extraction methods for effective isolation of fucoxanthin from algae have been investigated and compared. Method 1 of Extraction of fucoxanthin from Padina australis would give 8.12 mg of fucoxanthin/g of biomass with methanol, chloroform and methanol mixture (1:1 (v/v)) and then with chloroform. The ultrasonic assisted on the method 1 would yield 16.9 mg of fucoxanthin/g of biomass confirming that the ultrasonics increased the rate of extraction than that of extraction without ultrasonics. Thus, Ultrasonic assisted extraction is a potential method for isolation of fucoxanthin from marine macro algae Padina australis effectively.
