正2015年版《中国药典》是新中国成立以来的第10版药典。2010年3月第十届药典委员会组建成立,历时5年完成新版药典编制工作。编制期间,所有药典的修订内容均在网上公示并征求意见,共收到网上反馈意见4000余条,远远超过历版药典收到反馈意见的数量,反映了社会、公众对新版药典编制的关注度和参与度不断提高。新药典主要在以 相似文献

国家药监局不久前宣布,2010年版《中国药典》已经编制完成,将于明年7月1日实施。新版《中国药典》分为中药、化学药、生物制品3部,收载品种4600余种,其中新增1300余种,基本覆盖国家基本药物目录品种和国家医疗保险目录品种。据介绍,新版《中国药典》关注药品安全性,除在附录中加强安全性检查总体要求外,在品种正文标准中也大幅增加或完善安全性检查项目,进一步提高对高风险品种的标准要求,进一步加强对重金属或有害元素、杂质、残留溶剂等的控制,并规定眼用制剂按无菌制剂要求。新版药典对高风险药品尤为重视,增加了化学药注射剂安全性检查法应用指导原则;在制剂通则中将渗透压摩尔浓度检查作为注射剂的必检项目;对药典一部收载的中药注射剂品种全部增加了重金属和有害元素限度标准;此外对于其它注射剂品种的标准也不同程度地增加了对产品安全性、有效性及质量可控性等方面的质控要求。这些措施对于解决注射剂、特别是中药注射剂的安全性问题必将起到积极的作用。新版药典收载中药材、中药饮片、中成药和中药提取物标准大幅提升。新版药典共收载了2136个中药品种,比原来增加了900多种。在中药附录中加强安全性检查总体要求,在中药正文标准中增加或完善安全性检查... 相似文献

甘草霜中的甘草酸目前一直沿用《中华人民共和国药典》中常量法测定,既繁琐又费时。本文采用红外光谱直接定量法,不仅免去了化学前处理,简便省时,还防止了预处理带来的被测组份的污染损失。 1.仪器与试剂 P-E983红外分光光度计、3600数据站,660打印机,AD-2Z百万分之一感量电子天平。溴化钾(分析纯)。甘草酸标准品(按《中华人民共和国药典》中常量法提纯精制),纯度94.3%。 2.实验方法 相似文献

药物分析课程与家庭环境致癌因素教育的结合 总被引:2,自引:0,他引:2
对于现代人而言,对生命构成最大威胁的是心血管病,脑血管病和恶性肿瘤,而癌症将取代心脏病成为威胁人类生命的头号杀手[1]。癌症发病因素虽比较复杂,但环境因素是重要诱因,特别是室内空气污染以及不良生活习惯。因此医学院校学生(特别是药学专业学生)应适当增加家庭致癌因素方面教育。药物分析是一门研究与发展药品质量控制的方法学科,药品质量控制的方法都是《中国药典》所规范的方法,内容较为枯燥、乏味。且本课程是在学生学完药物化学、分析化学、仪器分析等课程之后开设的,所以部分内容有些与上述课程重复,可在授课时适当略过。另外,为… 相似文献

The compositions of the neutral diterpenoids of the oleoresins of five species of conifers growing in the Transcarpathia have been studied. It has been found that the oleoresins ofAbies alba M.,Larix decidua M., andPicea excelsa L. contain more than 50% of neutral diterpenoids. The group and qualitative compositions of the oxygen-containing diterpenoids have been determined. In the oleoresins ofAbies alba,Picea excelsa, andPicea abies tertiary alcohols — cis-abienol and isocembrol — predominate, while inLarix decidua the main component is the hydroxy ester larixyl acetate. Primary alcohols related to the resin acids have been found in all the oleoresins investigated. Features of the distribution of diterpenoids according to the species of conifers have been revealed. The results obtained are necessary for the chemotaxonomy of conifers of the family Pinceae.Novosibirsk Institute of Organic Chemistry, Siberian Branch, Academy of Sciences of the USSR.

Sets of hydrogen molecule equivalents have been developed which permit the calculation of hydrogenation of different types of carbon-carbon bonds from ab initio total energies (3-21G and 6-31G* basis sets, and, to a more limited extent, for MP2/6-31G* data) of reactants and products. The calculated enthalpies of hydrogenation are in good agreement with experiment for unstrained molecules, with average errors on the order of 2 kcal/mol. The 6-31G* equivalents allow the enthalpies for strained molecules to be calculated accurately, but the 3-21G equivalents do not. The equivalents for both basis sets have been tested by calculating the enthalpies of hydrogenation of carbon-carbon bonds in nitrogen- and oxygen-containing organic molecules, free radicals, and classical carbocations. The results are in good agreement with experiment in most cases. 相似文献

Influence of viscosity of medium on processes of oxygen quenching of excited states of mesoporphyrin
E. I. Kapinus V. A. Ganzha B. M. Dzhagarov E. I. Sagun V. B. Pavlenko 《Theoretical and Experimental Chemistry》1989,25(2):146-151
The oxygen quenching rate constants for singlet and triplet excited states of the dimethyl ester of mesoporphyrin IX increase with decreasing viscosity of the medium and reach a maximum at a viscosity of approximately 0.4 mPa·sec, after which the rate constants begin to decrease. The drop in rate constant with increasing fluidity of the medium may be related to a nonequilibrium character of the elementary act in the interaction of the reactants in the solvent cage. In viscous media such as isopropyl alcohol, isobutyl alcohol, and isoamyl alcohol, the reaction radius is greater than the sum of the radii of the reacting particles. The long-range character of these processes is due to the relatively weak dependence of the quenching probability on distance.Translated from Teoreticheskaya i Éksperimental'naya Khimiya, Vol. 25, No. 2, pp. 161–167, March–April, 1989. 相似文献
