摘要： 旨在探究桐花树根多糖的理化性质和抗酪氨酸酶活性。以水提法、酸提法、碱提法连续提取桐花树根多糖，经脱脂脱色、脱蛋白、透析等方法得到初步纯化的多糖，紫外检测与显色反应分析其理化性质；探究多糖对酪氨酸酶活性的影响。结果表明：桐花树根水提物的多糖（中性多糖）含量为34.02%，酸提物多糖（酸性多糖）含量为27.18%，碱提物的多糖（碱性多糖）含量为51.21%。在浓度0.2~1.0 mg/mL时，桐花树根中性多糖、碱性多糖对酪氨酸酶活性具有双向调节作用，当浓度小于0.4 mg/mL时，对酪氨酸酶活性具有抑制作用，当浓度大于0.6 mg/mL时，表现为激活作用；但酸性多糖对酪氨酸酶活性仅表现为激活作用。

Abstract: To study the physicochemical properties and anti-tyrosinase activity of polysaccharide in Aegiceras corniculatum root, the crude polysaccharides were extracted from Aegiceras corniculatum roots by the sequential extraction methods of water extraction, acid extraction and alkaline extraction. The crude polysaccharides were depurated by degreasing, decoloration, deproteinization and dialysis, its physicochemical properties were examined by UV analysis and various chromogenic reactions, the effects on tyrosinase activity were also researched. The results were as follows: the polysaccharide (neutral polysaccharide) content of aqueous extract from Aegiceras corniculatum roots was 34.02%, acidic polysaccharose content of acid extract was 27.18% , and alkaline polysaccharide content of alkali extract was 51.21% . At the polysaccharose concentration of 0.2-1.0 mg/mL, it was found that the neutral polysaccharide and acidic polysaccharose had dual-directional regulation effects on tyrosinase activity, which showed the inhibition effect under 0.4 mg/mL and activation effect above 0.6 mg/mL, but acidic polysaccharose only showed activation effect.
