摘 要: 对火棘水溶性多糖的PP-A3组分的理化性质进行了研究。结果表明:PP-A3的分子量约为210000u,其主要由阿拉伯糖组成,其中含有少量的葡萄糖和果糖,阿拉伯糖∶葡萄糖∶果糖=1.62∶1∶1.59,此外含氨基酸总量约为0.5%。 The physicochemical properties of PP-A3 from water-soluble Pyracanthafortuneana polysaccharides were studied in this paper. The results indicated that molecular weight of PP-A3 is about 210 000 u, and it was composed of arabinose, glucose and fructose in a molar ratio of 1.62:1:1.59 and some amino acids whose total content is 0.5 %.
