  crystal water
The results suggest that the reduction in tablet hardness is dependent on the dehydration of crystal water, and the values of the slopes indicate that the bonding energy of the unpulverized sample was stronger than that of the pulverized sample.
      
As a result, a three-dimensional framework of [Ca(H2O)H2Edta)] with built-in crystal water molecules is formed.
      
Its ionic structure is composed of [NiL]2+ complex cations, ClO4- outer-spheric anions, and crystal water molecules.
      
Under storage in light, the compounds decompose from the surface; in darkness I and II are stable, whereas III and IV can lose part of the crystal water.
      
The structures are built up of [RuNOCl5]2- (I, IV), [RuNOCl4OH]2- (II, III), and [RuNOCl4(H2O)]- (IV) complex anions, (n‐Bu4N)+ cations, and crystal water molecules (III, IV).

OBJECTIVE: To observe the effects of powdering by hand or by grinder and different powder size on the contents of crystal water and main components in four mineral drugs METHODS: Gravimetric method and titration method were used RESULTS: No significant effects on crystal water and components were found in coarsest and coarse powder comminuted by grinder and all powders by hand The content of crystal water was reduced and the contents of main components containing crystal water were...

OBJECTIVE: To observe the effects of powdering by hand or by grinder and different powder size on the contents of crystal water and main components in four mineral drugs METHODS: Gravimetric method and titration method were used RESULTS: No significant effects on crystal water and components were found in coarsest and coarse powder comminuted by grinder and all powders by hand The content of crystal water was reduced and the contents of main components containing crystal water were increased in other powders CONCLUSION:The mineral drugs with crystal water should be grinded into coarse powder

目的 :探讨手工、机械粉碎法及不同粉碎粒度对4种矿物药结晶水及主成分含量的影响。方法 :重量法、滴定法。结果 :机械粉碎所得最粗粉、粗粉、手工粉碎各粉末无影响 ,其余则结晶水减失 ,结晶水主成分含量偏高。结论 :含结晶水矿物药宜粉碎成粗粉。

AIM: To explore the machanism of calcined mica by comparing the difference in crystal structure and inorganic elements of raw mica and calcined ones. METHODS: Crystal structures were compared by IR spectrum and X-ray crystallography and the contents of element in the prevention were determined with ICP-AES. RESULTS: After being calcined,crystal phase transformation changed in gold mica and did not change in white mica.Both of their chemical composition changed,crystal water decreased and crystal...

AIM: To explore the machanism of calcined mica by comparing the difference in crystal structure and inorganic elements of raw mica and calcined ones. METHODS: Crystal structures were compared by IR spectrum and X-ray crystallography and the contents of element in the prevention were determined with ICP-AES. RESULTS: After being calcined,crystal phase transformation changed in gold mica and did not change in white mica.Both of their chemical composition changed,crystal water decreased and crystal defects increased.There were obvious differences in the contents of inorganic elements.The content in white mica was obviously more than that in gold mica.After being calcined,the value of K/Na in white mica decreased and the contents of Ca,Mg increased,while the content of Mg increased and the content of Ca decreased in gold mica. CONCLUSION: There are(actually) many differences in contents of elements and chemical structure in white and gold mica before and after being calcined,which may explain the mechanism of calcined mica.

目的:通过比较生煅白、金云母的晶体结构、无机元素的不同,以探讨煅制白、金云母的机制。方法:运用红外光谱、X-射线晶体衍射,比较生煅白金云母的晶体结构,采用等离子发射光谱(ICP-AES)测定它们的宏微量元素含量。结果:白云母煅后晶体物相基本不变,金云母煅后晶体物相改变,煅后两者化学组成改变,结构水减少,晶格空位增多,生煅金、白云母溶出液中宏微量元素存在明显差别,白云母溶出液元素各含量均明显超过金云母,白云母煅后,K/Na比值降低,Ca、Mg等元素含量增大,煅制的金云母溶出液中镁含量增大,钙含量降低。结论:白、金云母煅制后云母晶体化学组成发生改变,其溶出液中元素的种类及含量亦发生变化,可能是煅制后药效增强,白、金云母功效差异的机制之一。

Objective: To explore the effect of crystal water on deteriming content of baicalin.Methods: Baicalin samples containing different amount of crystal water were determined by HPLC.Results: The determining results of baicalin were accurate and stable on condition that the samples contain some crystal water or some impurities,and the determining results of baicalin were reduced remarkably on condition that the samples are anhydrous and pure.Conclusion: The determining results of baicalin contents...

Objective: To explore the effect of crystal water on deteriming content of baicalin.Methods: Baicalin samples containing different amount of crystal water were determined by HPLC.Results: The determining results of baicalin were accurate and stable on condition that the samples contain some crystal water or some impurities,and the determining results of baicalin were reduced remarkably on condition that the samples are anhydrous and pure.Conclusion: The determining results of baicalin contents were accurate and stable only if the oxygen in 1 place forms hydrogen bond,and the determining results of baicalin contents were reduced remarkably on condition that the oxygen in 1 place forms protonated ether of form positive carbonic.

目的:探讨结晶水对黄芩苷含量测定的影响。方法:对含水量不同的黄芩苷进行含量测定比较。结果:含有结晶水的样品含量测定结果准确、稳定;而纯的无水物含量测定结果显著降低。结论:能使1位氧原子形成氢键的条件可使含量测定结果准确、稳定;而使1位氧原子形成盐或形成碳正离子的条件使含量测定结果显著降低。
