The aim of this research was to estimate the steroid, flavonoid and antiradical activity of brown seaweed Sargassum wightii. The HPTLC analysis reveals the presence of polyphenolic signals at different ranges. The steroid and flavonoid content of ethanolic extract was observed in 0.35 Rf and presence of flavonoid in the given standard but not in the sample respectively. Scavenging activity was observed from 05 to 20mg/ml, 24 ± 1.3; 41.3 ± 2.4; 63.5 ± 2.3 and 73.1 ± 1.7, which showed significance of the active principles in S. wightii.
