【摘要】 目的:在国产云实属植物中寻找能替代进口塔拉生产单宁酸及没食子酸的品种资源。方法:用水浸法提取单宁酸,用碱水解法对单宁浸提浓缩液进行水解,对水解产物进行了鉴别,并进行了实验室规模试验。结果:3种植物单宁酸的含量(干基)分别为32.2%,46.6%,58.5%,折合原料与水解产物之比为:154∶1,11.8∶1,3.09～2.79∶1。结论:首次在我国云实属植物中找到了可替代进口塔拉的植物。更多还原

【Abstract】 Objective:To get Chinese Caesalpinia plants that can replace the imported Tara to produce tannin and gallic acid.Method:Extract tannin with water,condense and hydrolyze the extracts with alkali,the hydrolysates were identified.Furthermore,an enlarged scale experiment was conducted.Result:Tannin contents of the plants were 32.2%,46.6% and 58.5%respectively,the converted ratios of raw material to hydrolysate were 154:1,11.8:1,3.09～2.79:1.respectively.Conclusion:We got the Tara replacing plants in Chinese Caesalpinia plants for the first time.更多还原
