Biological activities of macroalgae in the Moudulung waters: bioactive compounds and antioxidant activity

---

This study aimed to determine the bioactive compounds and antioxidant activity of
macroalgae in Moudolung Waters. The bioactive compounds in seven samples of
macroalgae were extracted with methanol. Analysis of macroalgae bioactive compounds
was carried out qualitatively by determining the presence of bioactive compounds
including alkaloids, flavonoids, saponins, tannins, phenol hydroquinone, and steroids/
terpenoids. antioxidant activity was carried out using the DPPH (2,2-diphenyl-1-picrylhydrazyl-hydrate) method. Data were analyzed descriptively using Microsoft Excel and all
data are expressed as mean. The results showed that these seven macroalgae species have
bioactive compounds such as alkaloids, flavonoids, saponins, tannins, phenol
hydroquinone, and steroids/terpenoids which function as antioxidants. The highest
antioxidant activity was the MA6 (Turbinaria ornate) followed by MA1 (Hormopysa
triquetra), MA4 (Ulva flexuosa syn. Enteromorpha flexuosa), MA5 (Eucheuma
spinosum), MA2 (Sargassum muticum), MA3 (Gracilaria corticate), and MA7
(Ulva reticulata) were 75.25 mg/mL, 90.31 mg/mL, 134.52 mg/mL, 200.22 mg/mL,
216.91 mg/mL, 259.16 mg/mL, and 270.42 mg/mL, respectively. The results suggested
that Turbinaria ornate and Hormopysa triquetra could be used as an important substitute
for functional ingredients in foods and pharmaceuticals or nutraceuticals.
