摘要: 目的 研究红树植物榄李枝叶不同提取液对小鼠的急性毒性。方法 分别给予榄李枝叶的水和70%乙醇提取液灌胃给药后,观察小鼠的二便、活动、饮食、死亡等情况,用改良寇氏法计算半数致死量(LD50)及95%可信限。结果 榄李枝叶水提取液的LD50为65.47 g·kg-1,LD50的95%可信限为56.78~75.68 g·kg-1;70%乙醇提取液的LD50为62.26 g·kg-1,LD50的95%可信限为53.29~70.97 g·kg-1。结论 榄李枝叶的水及70%乙醇提取液均具有一定的毒性,其毒性与给药浓度相关。

Abstract: Objective To study the acute toxicity of different extracts of branches and leaves from mangrove Lumnitzera racemosa Willd. on mice. Methods After intragastric administration of the water or 70% ethanol extract of branches and leaves from Lumnitzera racemosa Willd. in mice, the urine and stools, activities, diet and death were observed daily. The median lethal dose (LD50) and 95% confidence intervals (95% CI) were calculated with the Karber method. Results The LD50 of the water extract was calculated to be 65.47 g·kg-1 and the 95% CI was 56.78~75.68 g·kg-1, compared with 62.26 g·kg-1 for 70% ethanol extract and 53.29~70.97 g·kg-1 for the 95% CI. Conclusion The Lumnitzera racemosa Willd. extracts have some toxicity that is related to the concentration of the drug.
