摘要: 研究碱性蛋白酶酶解制备米氏凯伦藻多糖及其抑制肿瘤血管活性。采用闪式萃取结合酶法制备米氏凯伦藻多糖,其适宜提取条件为碱性蛋白酶酶解温度40 ℃、酶解pH为8.5、酶用量为2.5%、酶解时间为2 h。其提取液经三氯乙酸除蛋白、乙醇沉淀获得米氏凯伦藻多糖。制备的米氏凯伦藻多糖在一定浓度时可抑制肿瘤细胞培养液诱导的内皮细胞增殖和迁移作用,具有一定的抑制肿瘤血管生成活性。

Abstract: To investigate the preparation method on karenia polysaccharides with alkali protease enzymolysis from Karenia mikimotoi and its anti-angiogenic activity.The extraction of karenia polysaccharides was obtained by flash extraction combined with enzymolysis method,and the optimal process conditions were determined as enzymolysis temperature of 40 ℃,pH 8.5,enzymolysis dosage of 2.5% and enzymolysis time of 2 h.The karenia polysaccharides were obtained by using trichloroacetic acid to get rid of protein and ethanol for precipitation.The karenia polysaccharides showed some inhibition on the viability and migration of induced human umbilical vein endothelial cells at certain concentration.

Key words: Karenia mikimotoi, polysaccharides, flash extraction enzymolysis, anti-angiogenic activity
