Determination of prednisolone in the presence of hydroxyzine and in formulations containing analgesics 强的松龙在羟嗪存在下和在含有止痛剂的制剂中的测定
Pub Date : 1960-12-01 DOI: 10.1002/jps.3030491206
J.D. Duerr , B.A. Pappas

A colorimetric method for the determination of prednisolone in the presence of hydroxyzine [1-(p-chlorobenzhydryl)-4-2-(2-hydroxyethoxy) ethyl piperazine], acetylsalicylic acid, caffeine, and acetophenetidin is proposed. Samples of tablet formulations containing prednisolone and the above mentioned compounds were assayed by the addition of sulfuric acid and ferric chloride to alcoholic solutions of the active ingredient and subsequent measurement of the absorbance of the resulting colored solutions.

建立了在羟嗪[1-(对氯苯羟基)-4-2-(2-羟基乙氧基)乙基哌嗪]、乙酰水杨酸、咖啡因和苯乙嘌呤存在下测定强的松龙的比色法。对含有强的松龙和上述化合物的片剂配方样品进行了分析,方法是在活性成分的酒精溶液中加入硫酸和氯化铁,然后测量所得有色溶液的吸光度。

Synthesis of some symmetrical aldehyde glycol monoether acetals 对称醛乙二醇单醚缩醛的合成
Pub Date : 1960-12-01 DOI: 10.1002/jps.3030491203
Arthur J. Getzkin , Werner M. Lauter

Forty-two acetals of seven aldehydes and the mono-methyl, ethyl and n-butyl ethers of ethylene glycol and diethylene glycol were prepared, and their physical constants determined. An in vitro test was used to determine their hydrolysis in a slightly acidic medium, considered to be similar to the natural acidity of the human skin. It was shown that regeneration of the parent aldehydes proceeded with sufficient rapidity to warrant in vivo tests of these acetals in cosmetic formulas.

制备了7种醛缩醛的42种缩醛以及乙二醇和二乙二醇的单甲基醚、乙基醚和正丁基醚,并测定了它们的物理常数。体外试验用于确定它们在微酸性介质中的水解,微酸性介质被认为与人体皮肤的自然酸度相似。结果表明,母体醛的再生速度足够快,足以保证在化妆品配方中对这些缩醛进行体内试验。

New approach to the determination of vitamin a in pharmaceutical products 药品中维生素a含量测定的新方法
Pub Date : 1960-12-01 DOI: 10.1002/jps.3030491202
Real Tardif

A modified analytical procedure for the determination of vitamin A in pharmaceutical preparations and its method of calculation based on geometric and trigonometric relationships is presented. Ether and isopropyl alcohol solvents are replaced by hexane, a more selective solvent, for the extraction of the unsaponifiable fraction. Absorbance readings of this latter are measured at one wavelength (325 mμ) before and after the destruction of vitamin A. A comparison study of the accuracy and precision of the U. S. P. XV method and of this proposed method was made on five characteristic polyvitamin preparations and on a cod liver oil sample. Statistical analysis of the results in per cent recovery of added vitamin A has shown a 100 per cent yield by the “hexane-destruction” method, and 82 to 96 per cent yield by the U. S. P. XV method. With this proposed method, the standard deviations were less than one-third as grdeat.

提出了一种改进的药物制剂中维生素A含量的分析方法及其基于几何和三角关系的计算方法。醚和异丙醇溶剂被己烷取代,己烷是一种选择性更强的溶剂,用于提取不皂化的部分。在维生素A破坏前后,在一个波长(325 μ)处测量了后者的吸光度值。在五种典型的多维生素制剂和鱼肝油样品上,比较了u.s.p . XV方法和该方法的准确度和精密度。对添加的维生素A的回收率进行统计分析,结果表明,“己烷破坏法”的收率为100%,美国p.v v法的收率为82%至96%。该方法的标准偏差小于三分之一。

A series of methyl glycosides (acetals and ketals) analogous to aldopyranosides, ketopyranosides, and their 3-hydroxy analogs (tetrahydropyran, 2-methyl-tetrahydropyran, and 3-hydroxyl derivatives of these compounds) were synthesized, subjected to acids of various concentrations, and their rates of hydrolysis determined spectrophotometrically.
