研究发现苦参乙醇提取物的二氯甲烷部分对蘑菇酪氨酸酶具有潜在的抑制活性。本次对其活性及活性成分作了进一步研究。植物提取分离:干燥的苦参根(3.65kg)经乙醇室温提取,过滤后,滤液真空挥干。将乙醇提取物溶于水,依次用二氯甲烷、乙酸乙酯及正丁醇萃取。活性指导分离,二氯甲烷 It was found that the dichloromethane portion of the ethanol extract of Sophora flavescens had potential inhibitory activity against mushroom tyrosinase. The activity and active ingredients were further studied. Plant extraction and separation: The dried Sophora flavescens root (3.65 kg) was extracted with ethanol at room temperature, filtered, and the filtrate was evaporated in vacuo. The ethanol extract was dissolved in water and extracted with dichloromethane, ethyl acetate and n-butanol in that order. Activity Guided Separation, Dichloromethane
