摘　　要：目的:对比刺五加根皮乙醇提取物(SENR)和短梗五加根皮乙醇提取物(SESR)的镇静催眠作用及其作用机制,探讨短梗五加根皮替代刺五加根皮的可行性。方法:根据测定指标的不同,选择雄性昆明小鼠360只,每120只随机分为空白对照组,地西泮组(DZP,3 mg·kg^-1,灌胃给药),不同剂量(4、8、16、32和64 mg·kg^-1)SENR组和不同剂量(4、8、16、32和64 mg·kg^-1)SESR组,每组10只,连续给药5 d,记录各组小鼠自主活动次数;利用亚催眠剂量(28 mg·kg^-1)戊巴比妥钠诱导睡眠实验记录小鼠睡眠发生率,利用催眠剂量(48 mg·kg^-1)戊巴比妥钠诱导睡眠实验记录小鼠睡眠潜伏期和睡眠时间,筛选出SENR和SESR的亚催眠剂量和催眠剂量。根据模型药[5-羟色氨酸(5-HTP)和氟马西尼(FLU)]的不同,雄性ICR小鼠180只,每60只随机分为空白对照组、模型对照组、SENR组、SESR组、SENR+模型药组和SESR+模型药组,每组10只,连续给药5 d,采用戊巴比妥钠诱导睡眠实验记录各组小鼠的睡眠发生率、睡眠潜伏期和睡眠时间,采用ELISA法测定小鼠脑组织中5-羟色胺(5-HT)和γ-氨基丁酸(GABA)水平。结果:与空白对照组比较,DZP组、不同剂量(8、16、32和64 mg·kg^-1)SENR组和不同剂量(8、16、32和64 mg·kg^-1)SESR组小鼠自主活动次数明显减少(P<0.05或P<0.01),睡眠发生率增加,睡眠潜伏期缩短且睡眠时间延长(P<0.05或P<0.01);依据实验结果,选择SENR和SESR的亚催眠剂量为4 mg·kg^-1,催眠剂量为32 mg·kg^-1。5-HTP模型实验,与空白对照组、SENR(4 mg·kg^-1)组和SESR(4 mg·kg^-1)组比较,SENR+5-HTP组和SESR+5-HTP组小鼠睡眠发生率增加,睡眠潜伏期缩短(P<0.01),睡眠时间延长(P<0.01),脑组织中5-HT水平升高(P<0.01);FLU模型实验,与空白对照组比较,SENR(32 mg·kg^-1)组和SESR(32 mg·kg^-1)组小鼠睡眠潜伏期缩短(P<0.01),睡眠时间延长(P<0.01);与SENR(32 mg·kg^-1)组和SESR(32 mg·kg^-1)组比较,SENR+FLU组和SESR+FLU组小鼠睡Objective:To compare the sedative and hypnotic effects of ethanol extract of Acanthopanax senticosus root bark(SENR)and ethanol extract of Acanthopanax sessiliflorus root bark(SESR)and their mechanisms,and to explore the feasibility of replacing Acanthopanax senticosus root bark with Acanthopanax sessiliflorus root bark.Methods:According to the different detection indexes,every 120 of 360 male Kunming mice were randomly divided into blank control group,diazepam group(administrated with 3 mg·kg^-1 DZP by gavage),different doses(4,8,16,32 and 64 mg·kg^-1)of SENR groups and different doses(4,8,16,32 and 64 mg·kg^-1)of SESR groups;there were 10 mice in each group.The mice were administrated for 5 d continuously,and the number of locomotor activities of the mice in various groups were recorded.The sub-hypnotic dose(28 mg·kg^-1)of pentobarbital sodium-induced sleep experiment was used to record the incidence of sleep of the mice,and the hypnotic dose(48 mg·kg^-1)of pentobarbital sodium-induced sleep experiment was used to record the sleep latencies and sleep time of the mice.The hypnotic doses and sub-hypnotic doses of SENR and SESR were screened out according to the above experimental results.According to the different model drugs[5-hydroxytryptophan(5-HTP)and flumazenil(FLU)],every 60 of 180 male Kunming mice were randomly divided into blank control group,model control group,SENR group,SESR group,SENR+model drug group and SESR+model drug group;there were 10 mice in each group.The mice were administrated for 5 d continuously,and pentobarbital sodium-induced sleep experiment was used to record the incidence of sleep latencies and sleep time of the mice in various groups,and the 5-hydroxytryptamine(5-HT)and gamma-aminobutyric acid(GABA)levels in brain tissue of the mice were detected by ELISA.Results:Compared with blank control group,the number of locomotor activities of the mice in DZP group,different doses(8,16,32 and 64 mg·kg^-1)of SENR and different doses(8,16,32 and 64 mg·kg^-1)of SESR groups was decreased(P
