| 摘 要： | 目的]分离纯化白蔹多糖,研究白蔹均一多糖对小鼠脾淋巴细胞增殖的影响。方法]采用水提醇沉法提取白蔹多糖,通过三氯乙酸法脱除蛋白,用中空纤维超滤膜和DEAE Cellulose DE-52对白蔹多糖进行分离纯化,高效凝胶过滤色谱法鉴定纯度并测定分子量,PMP柱前衍生化测定单糖组成,采用MTT法测定均一多糖对Con A和LPS诱导的小鼠脾淋巴细胞增殖的影响。结果]PAJM-A均一多糖分子量为1.29×105u,由甘露糖(Man)、鼠李糖(Rha)、葡萄糖醛酸(Glc A)、半乳糖(Gal)、葡萄糖(Glc)、木糖(Xly)组成,其物质的量比为1.36∶1.87∶2.02∶1.58∶1.04,均一多糖对Con A诱导的T淋巴细胞和LPS诱导的B淋巴细胞有较显著的增殖作用。结论]PAJM-A是一种新的白蔹均一多糖,并与Con A、LPS对T、B淋巴细胞的增殖有协同刺激作用。

| Abstract: | Objective] To separate and purify polysaccharides from Ampelopsis Japonica ( Thunb.) Makino, and to study its effects on prolif-eration function of mice spleen lymphocyte transformation.Method] Hot water extracting and TCA method were employed to isolate the PA-JM.Hollow fiber ultrafiltration membrane and the DEAE Cellulose 52 were used to separate and purify polysaccharides, and the monosaccha-ride composition, and structure were preliminarily identified by IR and HPLC.Their effects on proliferation function of mice spleen lymphocyte transformation were determined by MTT.Result] PAJM-A was 1.29 ×105 u and it was mainly composed of Man, Rha, GlcA, Glc, Gal and Xyl in the molar ratio of 1.36∶1.87∶2.02∶0.10∶1.58∶1.04.And the homogeneous polysaccharides were able to increase the proliferation of lymphocytes induced by ConA and LPS. Conclusion] PAJM-A is a novel homogeneous polysaccharide, PAJM-A can effectively increase lymphocyte proliferation and enhance the effect of ConA, LPS-induced T and B cell growth. |
