         The separation, identification, and determination of epimer of tetracycline have been attempted paper-chromatographically based on the principle of Selzer's method. Some improvements were made to effect an efficient separation and identification. It was demonstrated experimentally that results from Selzer's method were not reliable owing to partial inversion of tetracycline in the course of chromatography. However, better results could be obtained through the modification of the solvent system. In order to...
            本文报告了四环素中差向异构体的紙上层析分离鉴定及定量方法。四环素中差向异构体的分离鉴定是在selzer法基础上加以改进的。本試驗証实該法在层析过程中有部分四环素轉化,結果不可靠,改进溶剂后可得到良好分离。四环素中差向异构体的定量是經层析后,将异构体部分剪下,以0.1N硫酸分多次洗下,再用分光光度計在355毫微米处測定,以E_1~(1%)值=333計算差向异构体的含量。

         The present paper deals with the synthesis of peptide Ⅰ(N-carbobenzoxyglycyl-L-isoleucyl-L-valyl-γ-tert-butyl-L-glutamyl-L-glutamine carbo-tert-butoxyhydrazide) and peptide Ⅱ (N-carbobenzoxyglycyl-L-isoleucyl-L-valyl-L-glutamyl-L-glutaminyl-S-benzyl-L-cysteinyl-S-benzyl-L-cysteinyl-L-alanyl-L-serine hydrazide), which are protected N-terminal penta-and nona-peptides of the A-chain of bovine insulin respectively. Peptide Ⅰ was prepared from the known tripeptide Ⅲ (N-carbobenzoxy-L-isoleucyl-L-valyl-γ-tert-but...
            本文叙述带保护基的牛胰岛素A链氨端五肽Ⅰ(N-苄氧羰基甘氨酰-异亮氨酰-缬氨酰-γ-叔丁酯谷氨酰-谷氨酰胺酰肼基甲酸叔丁酯)及九肽Ⅱ(N-苄氧羰基甘氨酰-异亮氨酰-缬氨酰-谷氨酰-谷氨酰胺酰-S-苄基半胱氨酰-S-苄基半胱氨酰-丙氨酰-丝氨酰脐)的合成。Ⅰ是由已知三肽Ⅲ(N-苄氧羰基异亮氨酰-缬氨酰-γ-叔丁酯谷氨酸乙酯)经二种不同的合成步骤分别缩合而得,五肽Ⅰ经三氟乙酸脱去γ-叔丁基和N-叔丁氧羰基后与已知四肽Ⅷ(S-苄基半胱氨酰-S-苄基半胱氨酰-丙氨酰-O-乙酰丝氨酸甲酯溴氢酸盐)借迭氮法缩合而得九肽酯Ⅸ再经肼解而得九肽肼Ⅱ。合成的三肽、四肽、五肽和九肽的化学纯度曾经纸层析、纸电泳、元素分析及氨基酸组成分析证明,其光学纯度(除九肽Ⅱ和Ⅸ外)皆曾经亮氨酸氨肽酶水解及水解物的氨基酸组成测定证明为L型,九肽Ⅸ是由光学纯L型的肽Ⅰ与Ⅷ经迭氦法缩合而成,因此Ⅸ以及Ⅱ很可能为光学纯L型。
