从薏苡仁中提取并经硅胶层析分离而得的新磷脂酰胆碱钙能溶于甲醇和氯仿,难溶于丙酮,可作为活性氧的抑制剂及消炎药。方法:将4kg的薏苡仁在氯仿-甲醇(2:1)混合液中浸泡10min,用甲醇-0.1mol/LKCI(1:1)混合溶液作Folch洗涤。将所得的部分在氯仿、丙酮和甲醇中进行层析分离,可分得一个中性组份,一个磷脂酰乙醇胺组份和一个磷脂酰胆碱组份。其中溶于甲醇的组份经氯仿-甲醇(9:1或4:6)混合液进一步
The new phosphatidylcholine calcium extracted from Coix Seed and separated by silica gel can be dissolved in methanol and chloroform, insoluble in acetone, and can be used as an inhibitor of active oxygen and anti-inflammatory drugs. Methods: 4 kg of Coix Seed was soaked in chloroform - methanol (2: 1) mixture for 10 min and washed with Folch with methanol - 0.1 mol / L KCI (1: 1) The resulting fraction was chromatographed in chloroform, acetone and methanol to obtain a neutral fraction, a phosphatidylethanolamine fraction and a phosphatidylcholine fraction. The methanol-soluble components were further mixed with chloroform-methanol (9: 1 or 4: 6)
