本研究从芦荟(Aloe vera L.var.chinensis(Haw.)Berger)中分出三个多糖(A_(60) A_(90a)、和 A_(90b)分子量分别为12,000、47,000和12,000。除 A_(9Ca)的量过少,未作分析外,A_(60)的结构被推断为β-(1→4)连结的甘露聚糖,在2,3或6位上部分乙酰化;A_(90b)的结构被推断为β-(1→4)结构的直链葡萄-甘露聚糖。实验表明A_(60)对小鼠淋巴细胞转化功能和腹腔巨噬细胞的增殖均有一定的促进作用。因此,可作为抗肿癌的辅助药,在治疗免疫功能低下方面可能有应用价值。
In this study, three polysaccharides were isolated from Aloe Vera L. var. Chinensis (Haw. Berger) (A 60 A 90a and A 90b) with molecular weights of 12,000, 47,000, and 12,000, respectively. The amount of (9Ca) was too small. Without analysis, the structure of A_(60) was inferred as β-(1→4)-linked mannan, partially acetylated at 2, 3 or 6; A_(90b) The structure of the structure was deduced to be a straight-chain grape-mannan with a β-(1→4) structure.Experiments have shown that A_(60) has a certain role in promoting lymphocyte transformation and peritoneal macrophage proliferation in mice. Therefore, it can be used as an adjunct to anti-tumor cancer and may have application value in the treatment of immune dysfunction.
