摘要
抗中暑速效喷雾剂是由诸葛行军散经处方筛选,由传统的散剂改革而成,具有作用迅速、剂量小、给药方便等特点。
     目的:1)对诸葛行军散进行处方筛选,在不改变疗效的情况下制定更适合本剂型的处方。
     2)建立麝香酮、胆酸含量测定方法。
     3)筛选出干姜、霍香挥发油、牛黄、麝香的最佳提取工艺。
     4)筛选成型工艺。
     5)制定质量标准
     方法:1)将经不同处理的大鼠热暴露人工气候室里(温度41℃、相对湿度70%),测定各组大鼠肛温及死亡时间,考察了抗中暑速效喷雾剂与诸葛行军散在降低大鼠体温、延长存活时间、降低死亡率上的差异。
     2)麝香酮的含量测定采用了GC法,胆酸的含量测定采用了紫外分光光度法,
     3)采用正交设计方法筛选干姜、霍香挥发油、麝香、牛黄的最佳提取工艺和成型工艺。
     4)采用已建立好的麝香酮、胆酸的含量测定方法确定麝香酮、胆酸的含量。采用薄层色谱法对冰片、霍香、干姜进行定性鉴别。
     结果:1)抗中暑速效喷雾剂能明显地降低热环境下大鼠肛温、死亡率和延长大鼠存活时间,且效果好于诸葛行军散。
     2)麝香酮、胆酸的含量测定方法的线性回归方程和相关系数分别为y=-0.00114+1.099×10~(-9),R=0.9999;y=-0.365+18.86x,(ug/ml) R=0.9999。加样回收率分别为麝香酮为98.82—101.71% 胆酸99.41—102.03%稳定性、精密度、重现性的RSD均小于1%
     3)霍香和干姜挥发油、牛黄、麝香最佳提取工艺分别为:10倍量的水水蒸汽蒸馏7小时;20倍量的氯仿超声提取两次,每次20分钟;加10倍量的乙酸乙酯超声提取两次,每次20分钟。
     4)成品麝香酮、胆酸的含量分别0.0493—0.0553mg/ml、0.3974—0.5227mg/ml含量均介于相应的口服液与注射液之间。
     结论:抗中暑速效喷雾剂经过处方筛选、提取工艺、成型工艺的研究、各
    
    项指标表明该制剂具有组方合理、疗效显著、工艺可行、质量可控。为下
    一步实验提供基础。
pharmaceutics of quick result resist heat stroke is adjusted from the ZhuGeXinJun powder through prescription screening. It is more effective for the prevention of heat Stroke. Objective:
    1) To obtain a new prescription which is more suit for spray on the base of the prescription of ZhuGeXinJun powder.
    2) To develop a assay method for Muscone and cholalic.
    3) To screen the best extract technique for Volatile oil, cow-bezoar and Musk.
    4) To screen a moulding technique.
    5) To enact a quality criterion. Methods:
    1) Heat exposure rats which have been treated with several different methods in phytotron (41?, relative humidity 70%), estimated the death time and the temperature from the anus of the rat, and then compare the difference of the temperature, survival data and mortality between the Preventive heat Stroke Spray and the ZhuGeXinJun powder.
    2) Using the GC method to assay the content of Muscone, using the UV spectrophotometer to assay the content of cholalic acid.
    3) Orthogonal design was used to screen the best extract method and moulding method for Volatile oil, Musk and cow-bezoar.
    4) Using developed content assay methods to estimate the contents of Muscone and cholalic acid. Thin layer chromatogram scanner was used to qualitative Identificate the borneo camphor Pogostemon and dried ginger.
    Results:
    1) Preventive heat Stroke Spray is better for decreasing the temperature, amelioration survival data and decreasing mortality than the
    
    
    ZhuGeXinJun powder in a low-heat enviroment.
    2) The linear regression equation and correlation coefficient of content assay methods for Muscone is y=-0.00114+1.099x109 , R=0.9999. and the linear regression equation and correlation coefficient of content assay methods for cholalic acid is y=-0.365+18.86x (ug/ml) R=0.9999. The callback rate for Muscone is 98. 88-101. 71% .The callback rate for cholalic acid is 99.41- 102.03%. All the RSDs of stability, precision and reduplication for both Muscone and cholalic acid are less than 1%.
    3) The best extract technique for Pogostemon dried ginger Volatile oil ,cow-bwzoar and Musk is stilling Pogostemon and dried ginger Volatile oil with ten times quantity ree for 7 hours; ultrasound extraction cow-bwzoar twice times with 20 times Chloroform, each tune is 20minutes; ultrasound extraction Musk twice times with 20 times acetic ether, each time is 20minutes.
    4) The content of Musk is 0.0493-0.0553mg/ml. The content of cholalic acid is 0.3974-0.5227 mg/ml. Both contents are between Oral drug preparation and parenteral solution and its suits for norm of Spray.
    Conclusion:
    Through the screening of prescription ,extraction methods and mouding methods, we get the end product of Preventive heat Stroke Spray .All the assay results show the prescription is reasonable, the effect is significant, the technique is feasible and its quality can be controlled . All above has done a foundation for the next study.
