Abstract

|
This study was conducted to investigate changes in the external morphological and chemical compositions of Sargassum horneri according to collection time as well as determine the total polyphenol content and antioxidant activity based on different extraction solvents. The carbohydrate contents of S. horneri according to month were 45.1∼59.3%, crude protein contents were 19.0∼26.2%, and crude lipid contents were 1.08∼2.85%. The extraction yields and polysaccharide contents of hot water extracts were significantly higher than those of ethanol extracts (P<0.05). The total polyphenol contents and 1,1-diphenyl-2-picrylhydrazyl and 2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt radical scavenging activities were the highest in May for the 70% ethanol extracts. As a result, May was shown to be the most suitable month to collect S. horneri as a functional food material. In May, S. horneri constituted a large portion of the population and had higher carbohydrate and crude protein contents. Moreover, ethanol extracts had higher total polyphenol contents and antioxidant activities.
