摘　　要：自制了系列分子量规格的白芨多糖对照品(BT01～05),采用凝胶渗透色谱示差/多角激光光散射(GPC-RI/MALLS)技术测得其分子量,粘度法测得以水为溶剂、25℃条件下的特性粘数,建立白芨多糖的Mark-Houwink方程为[η]=7×10-4M1.10.5 standards（BT 01～05） of polysaccharides from Bletilla striata were prepared.Their molecular weights were obtained by gel permeation chromatography-refractive index/multi-angle laser light scattering（GPC-RI/MALLS） techniques and the intrinsic viscosity in pure water at 25 ℃ were measured by viscosimetry.As a result,the Mark-Houwink Equation of polysaccharides from Bletilla striata was established as [η] = 7×10-4M 1.10.
