The purified total sterols and beta-sitosterol extracted from Sargassum horneri were evaluated for their antidepressant-like activity using the forced swim test (FST) and tail suspension test (TST) in mice. Total sterols and beta-sitosterol significantly reduced the immobility time in the FST and TST. Total sterols were administered orally for 7 days at doses of 50, 100, and 200 mg/kg, and beta-sitosterol was administered intraperitoneally at doses of 10, 20, and 30 mg/kg. beta-sitosterol had no effect on locomotor activity in the open field test. In addition, total sterols and beta-sitosterol significantly increased NE, 5-HT, and the metabolite 5-HIAA in the mouse brain, suggesting that the antidepressant-like activity may be mediated through these neurotransmitters.
