After extracting lipids from gonadal tissue of crustacean by Folch method, colored lipid fraction is obtained. The lipid fraction is mixed with carotenoid pigments. Is there any method to get lipid alone without the interference of carotenoids?
Are there any method to extract carotenoids without contamination from lipids? If available, you can extract all the caroteinods first and then try extraction of lipids.
