| 摘 要： | 试验以新鲜牦牛血液为原料，采用血粉法、冰醋酸法及醋酸钠法，探索制备氯化血红素的最优工艺参数，并对不同方法制备的氯化血红素纯度及得量进行对比。结果显示，血粉法的最优工艺是超声处理时间40 min，酸性丙酮添加量为120 mL，抽提时间30 min，乙酸钠添加量为9 mL，氯化血红素纯度达到96%，得量为7.38 g/L。采用冰醋酸法制备氯化血红素，当冰醋酸添加量为红细胞量的3倍时，氯化血红素纯度达到80%，得量为6.10 g/L。采用醋酸钠法制备氯化血红素，当氯仿添加量为红细胞量的2倍时，氯化血红素纯度达到90%，得量为3.44 g/L。通过对比3种制备方法，氯化血红素纯度依次为血粉法 > 醋酸钠法 > 冰醋酸法；氯化血红素得量依次为血粉法 > 冰醋酸法 > 醋酸钠法，由此可知，3种方法中，选用血粉法制备氯化血红素的量更高且更加有利于工业化生产。 |

| Abstract: | The study was conducted to separate and purify the hemin from yak blood and the optimal process of preparing the hemin was confirmed using blood meal,glacial acetic acid and sodium acetate methods. The purity and the yield of the extracted hemin in different methods were compared. The results showed that the purity of hemin in yak blood was 96% and the yield was 7.38 g/L using blood meal method under the optimal process of 40 min for ultrasonic treatment, 30 min for extraction,120 mL acid acetone and 9 mL sodium acetate. The purity of hemin was 80% and the yield was 6.10 g/L when the amount of glacial acetic acid was 3 times as much as blood cells amount using the glacial acetic acid method.The purity of hemin was 90% and the yield was 3.44 g/L when the amount of chloroform was 2 times as much as blood cells amount using sodium acetate method. The purity of the hemin from high to low was blood meal method,sodium acetate method and glacial acetic acid method,and that of the hemin yield was blood meal method,glacial acetic acid method and sodium acetate method by comparing the three preparation methods. So the blood meal method was more conducive to industrial production. |
