| 摘 要： | 人黄连木叶获得的提取物，经葡聚糖凝ｅｐｈａｄｅｘＬＨ－２０分离得到的各种含单宁级分，用硫酸水解，水解液经纸层析检测，表明含有没食子酸和Ｄ－葡萄糖，证实黄连木叶宁是Ｂａｎｇ单宁，用ＵＶ光谱测得黄连木叶提取物含有游离和结合的没食子酸，一为２９．２０％。这种单宁经纯化后，用它代替工业单宁酸制备三甲氧苄氨嘧啶（简称ＴＭＰ）抗菌增效的中间体（三甲氧基苯甲酸甲酯和三甲基苯酰肼），初步获得成功。

| Abstract: | Extract from Pistacia chinensis leaf was chromatographically separated by Sephadex LH-20 column to fractions containing tannin which was identified as gallotannin by sulfuric acid hydrolysis of these fractions yielding gallic acid and D-glucose. Free and combined gallic acid in leaf extract amounted totally to 29. 20%.After purification,this tannin has been successfully utilized in this experiment to replace tannic acid in preparing methyl trimethoxybenzoate and trimethoxybenzamide, which are intermediate products of the pharmaceutical trimethoprim. |
