Abstract:
In this study, we investigated the antioxidative and antimicrobial activities of red algae Gloiopeltis tenax (GT). GT was extracted with methanol and then further fractionated it into four different types: methanol (GTMM), hexane (GTMH), butanol (GTMB) and aqueous (GTMA) soluble fractions. The antioxidant activity of the fractions from GT was investigated by measuring the scavenging activities of GT against reactive oxygen species (ROS) and reactive nitrogen species (RNS). Among the four fractions of GT, GTMM and GTMB showed a marked scavenging effect against ROS, but they displayed very low levels of the scavenging effect against RNS. The antimicrobial activity was increased in proportion to its concentration by the paper disc method. Among the various solvent layers, the GTMM and GTMB showed strong antimicrobial activities.
