为探讨铁棒锤的毒效关系,提取分离其氯仿部位并采用HPLC分析其主成分,比较了该部位与铁棒锤其他活性部位的急性毒性,以热板法和扭体法考察了不同剂量铁棒锤氯仿部位对小鼠的镇痛作用.结果表明:铁棒锤不同部位对小鼠急性毒性强度差别较大,氯仿部位的毒性最强,正丁醇和石油醚部位次之,三者的LD50分别为37.514,6766.928,5492.337 mg/kg.不同剂量的铁棒锤氯仿部位均能提高小鼠热板痛阈值,呈剂量依赖性关系.20 mg/kg铁棒锤60 min时的镇痛百分率为108.7%,远低于阳性对照10 mg/kg吗啡组(261.6%),但高于同剂量的铁棒锤总提物组(75.2%).不同剂量的铁棒锤氯仿部位均能有效抑制冰醋酸对所致小鼠扭体反应,呈剂量依赖性关系.20 mg/kg组的扭体抑制率为76.4%,明显高于200 mg/kg阿司匹林(50.5%)和20 mg/kg总提物组(51.0%).说明铁棒锤氯仿部位具有显著的毒性和镇痛活性呈剂量依赖性,推测其镇痛活性与毒性存在一定的关联.
為探討鐵棒錘的毒效關繫,提取分離其氯倣部位併採用HPLC分析其主成分,比較瞭該部位與鐵棒錘其他活性部位的急性毒性,以熱闆法和扭體法攷察瞭不同劑量鐵棒錘氯倣部位對小鼠的鎮痛作用.結果錶明:鐵棒錘不同部位對小鼠急性毒性彊度差彆較大,氯倣部位的毒性最彊,正丁醇和石油醚部位次之,三者的LD50分彆為37.514,6766.928,5492.337 mg/kg.不同劑量的鐵棒錘氯倣部位均能提高小鼠熱闆痛閾值,呈劑量依賴性關繫.20 mg/kg鐵棒錘60 min時的鎮痛百分率為108.7%,遠低于暘性對照10 mg/kg嗎啡組(261.6%),但高于同劑量的鐵棒錘總提物組(75.2%).不同劑量的鐵棒錘氯倣部位均能有效抑製冰醋痠對所緻小鼠扭體反應,呈劑量依賴性關繫.20 mg/kg組的扭體抑製率為76.4%,明顯高于200 mg/kg阿司匹林(50.5%)和20 mg/kg總提物組(51.0%).說明鐵棒錘氯倣部位具有顯著的毒性和鎮痛活性呈劑量依賴性,推測其鎮痛活性與毒性存在一定的關聯.

To study the toxicity of Aconitum Pendulum Busch.its chloroform extract was separated and analyzed by HPLC . An acute toxicity test was used to compare the toxicity of different extracts , then hot-plate test and acid-induced writhing test were used to assess the analgesic effect of the 20, 10, and 5 mg/kg chloroform extracts.The results indicated that the toxicity varied among different extracts .The most toxic extract was that of chloroform , followed by n-butyl alcohol and petroleum ether, of which the LD50 was 37.514, 6766.928, 5492.337 mg/kg respectively.Different doses of chloroform extract could all increase the pain threshold in a dose-dependent manner in hot plate test .The analgesia percentage of the 20 mg/kg chloroform extract was 108.7%in 60 minutes, far less than that of the 10 mg/kg morphine (261.6%), but was larger than that of the total extract ( 75.2%) .Different doses of chloroform extract could inhibit acetic acid induced writhing response in a dose-dependent manner .The writhing inhibition rate of the 20 mg/kg chloroform extract was 76.4%, significantly higher than that of the 200 mg/kg aspirin (50.5%) and the 20 mg/kg total extract (51.0%).The chloroform extract exhibited significant toxicity and analgesic activity in a dose-dependent manner , and there is probably some correlation between the analgesic activity and toxicity .
