Astaxanthin is a colored, lipid soluble pigment which is an effective antioxidant. Natural Astaxanthin from prawn shell waste could be a better alternative for synthetic orange red pigment. In India, 3 percent of exports are marine products. The wastes produced from marine processing industries possess a great environmental threat which can be recycled into a better alternative product. These wastes are a larger source of natural carotenoids that has varied pharmaceutical potentials. Astaxanthin finds its application in food additive and pharmacology mainly in cosmetology and anti-diabetic activity. It was extracted from shell waste by using organic solvent extraction method. Astaxanthin yield obtained using acetone solvent extraction was 12.5mg/g. The extracted Astaxanthin was confirmed using TLC which proved the presence of astaxanthin. FTIR studies revealed the presence of the functional groups. NMR indicated the protons present in the molecule. The antioxidant studies revealed the perfect antioxidant activity of astaxnthin. Hence this studies shows that astaxanthin from shrimp had better alpha amylase inhibition activity.
