Experimental Study of Different Effective Part of the Solvent Extraction of Kelp

Abstract

In this study, seaweed kelp, respectively, with petroleum ether, chloroform, ethyl acetate, n-butyl alcohol, distilled water kelp extract effective parts, and its contents were measured. The results show that: effective parts kelp has some antioxidant properties, its strength depends on the extraction solvent, with different organic solvents for extraction kelp, each extract antioxidant activity order: ethyl acetate extract> chloroform extract> n-butanol extract> aqueous layer extract. Each component seaweed extract contains flavonoids and polyphenols composition and content of different types, but most of ethyl acetate containing the sum of both.
