摘要
应用分光光度法洲定21例正常人和22例扩张型心肌病患者血浆中维生素E的浓度,结果分别为8.11±2.02和6.37±1.48μg/ml,两者相差非常显著(P<0.01)。作者还对血浆中维生素E的萃取溶剂进行了研究,用邻二甲苯、正庚烷,正已烷分别对同一血浆样品萃取维生素E,并测定其浓度,结果分别为5.57±0.38,5.78±0.14,4.82±0.26μg/ml,正庚烷萃取效果较好。
Concentration of plasma tocopherol of 21 normal volunteers and 22 patients of dilated cardiomyopathy was determined with a spectrophotometer.The results were 8.11±2.02μg/ml and 6.37±1.48μg/ml, respectively. The concentration of tocopherol in the plasma from the patients was remarkably lower than that from normal volunteers (P<0.01).The extracted solvent of tocopherol was studied. o-Xylene,n-heptane and n-he-xane were separately used toextract tocopherol from the same plasma. Then the tocopherol concentration was determined The results obtained were 5.57±0.38μg/ml, 5,78 ±0.14μg/ml, and 4.82±0.26μg/ml, respectively. n-Heptane had the best effect on extracting tocopherol from plasma.
