The purified total sterols and β-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 β-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 β-sitosterol was administered intraperitoneally at doses of 10, 20, and 30 mg/kg. β-sitosterol had no effect on locomotor activity in the open field test. In addition, total sterols and β-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.
利用强迫游泳试验（FST）和悬尾试验（TST），对从鼠尾藻中提取的纯化总甾醇和β-谷甾醇的抗抑郁样活性进行了评估。总甾醇和β-谷甾醇显著缩短了FST和TST中的不动时间。总甾醇以50、100和200mg/kg的剂量口服给药7天，β-谷甾醇以10、20和30mg/kg的剂量腹腔注射给药。β-谷甾醇在旷场试验中对运动活性没有影响。此外，总甾醇和β-谷甾醇显著增加了小鼠脑中的去甲肾上腺素（NE）、5-羟色胺（5-HT）及其代谢产物5-羟吲哚乙酸（5-HIAA），这表明抗抑郁样活性可能是通过这些神经递质介导的。
