红景天提取物皮下注射100mg/kg,一次给药或连续三天给药均有抗游泳疲劳作用,100mg/kg一次给药具有抗抓棒疲劳作用,100—200mg/kg 均无增强或拮抗戊巴比妥钠催眠作用,90mg/kg 无抗常压缺氧作用,45—200mg/kg一次或多次给药均无抗低压缺氧作用,10mg/kg 无抗肾上腺素高血糖作用。红景天浸膏灌胃给药1.25—10.0g/kg 一次给药,或5g/kg 连续六天给药均无抗抓棒疲劳作用。红景天提取物给小鼠灌胃给药 LD_(50)为45.01±7.37g/kg,给小鼠腹腔注射 LD_(50)为2.68±0.67g/kg。
Rhodiola extract was subcutaneously injected with 100 mg/kg. One dose or three consecutive days of treatment all had anti-fatigue effect. One dose of 100 mg/kg had anti-scratch stick fatigue, and 100-200 mg/kg did not enhance or antagonize. Hypnotic effect of sodium pentobarbital, 90mg/kg no resistance to normal hypoxia, 45-200mg/kg one or more doses have no anti-hypotension effect, 10mg/kg no anti-adrenergic hyperglycemia effect. Rhodiola extract was administered by intragastric administration at a dose of 1.25-10.0 g/kg once, or 5 g/kg for six consecutive days without any anti-grabber fatigue. Rhodiola extract was given to the mice by gavage with an LD 50 of 45.01±7.37 g/kg, and an intraperitoneal injection of LD 50 in the mice was 2.68±0.67 g/kg.
