Abstract

Introduction: The aim of this study was to investigate the phytochemical compounds (sterol, phenol and flavonoids) and antioxidant activity (diphenyl picryl hydrazyl (DPPH)) of premix extracts of brown macroalgae Padina australis, Sargassum ilicifolium and Stoechospermum marginatum.
Materials & Methods: In this study, after collecting macroalgae from the tidal areas of Chabahar coast, they were washed and after drying in a ratio of 1:1:1, they were combined and turned into powder. Sterol was measured by gas chromatography and phenol; flavonoids and antioxidant activity were measured by spectrophotometer.
Results: The results showed that sterol was the predominant sitostanol. The amount of total sterol, cholesterol and delta 5 avenasterol were 368.78±24.12, 10.02±2.12 and 3.54±0.06 mg/100 g of dry matter, respectively. The highest phenolic content (132.46±11.07 mg GAE g-1 extract), flavonoids (25.51±0.67 mg QE g-1 extract) and anti-radical activity of DPPH (1967.32±31.07μmol TE g-1 extract)) was observed in ethanolic extract of premix macroalgae. The levels of phenol, flavonoids and antioxidant activity were higher in ethanol, ethanol-aqueous and aqueous extracts, respectively, and showed a significant difference (P<0.05).
Conclusion: Overall, sitostanol was the predominant sterol of the macroalgae premix tested, and the ethanolic extract of the macroalgae premix showed the best flavonoid content, phenol, and antioxidant activity that can be recommended as rich sources of sterols and natural antioxidants for the food industry.
