Abstract:ObjectiveToevaluate theacutetoxicityof Glycosmis paruflorae(Sims)Kurz water extract inmice.Methods The maximum dosage(MAD)wasused inthe acute toxicityexperiment on mice.40 KMmice,2O malesand2O females,were selected andrandomlydividedintotwogroups with2Omiceineachgroup.Thetreat groupwasgiventhewaterextractofGlycosmisparviflore at a volume of 40mL/kg by gavage,and the control group was given equivalent pure water, observed and recorded general condition of mice(toxicreaction,body weightanddeath)within14days.After14days,theserum wastakentodetectthebloodbiochemical indexes,observedthepathologicalchangesinthemainorgansadcaleulatedtheorganindex.Inadition,histopathologicalchangs inthe organ wereanalyzedby hematoxylinandeosin method.ResultsThere werenoobvious toxic symptoms inthetreat group,and nosignificantdiferenceintebdyweights,matologicalandochemicalparametersaswellasistopatologyinorganshncompared with thecontrol group.Conclusion The MAD of water extractof Glycosmis paruflorae((Sims)Kurz for mice was 218g/kg , which was 872 times of the recommended dosage for adults ( 60kg ).Indicatedt hat Glycosmis parviflorae(Sims)Kurz was high safety.

山桔葉為蕓香科山小橘屬小花山小橘Glycosmisparviflorae(Sims)Kurz的干燥葉,別名野沙柑、酒餅木、山油甘等,具有止咳、化痰、消積、破瘀消腫的功效,在廣西、廣東、福建、臺灣等均有分布[1-2]。民間常用于治療感冒咳嗽、食積脹痛等。化學研究[3-7]表明,山桔葉主要含萜類、甾體類、黃酮苷類、脂肪酸類化合物。而其藥理作用報道較少,僅見抗炎、鎮痛相關報道[8-9]。基于此,本研究將初步探討山桔葉水提物的急性毒性,為臨床上合理、安全使用山桔葉提供參考。
