摘　　要：目的:测定并比较不同生长期甘草中多糖含量,为甘草的质量评价提供依据。方法:采用苯酚硫酸比色法,以葡萄糖作为对照品,在490nm处测定多糖含量。结果:不同生长期栽培甘草中多糖含量:1年生含量11.75,2年生含量11.07,3年生含量7.88。结论:1年生的甘草是含甘草多糖最适宜采收的生药。AIM: To measure and compare the content of glycyrrhizic polysaccharides in Glycyrrhiza in three different growth time. METHODS: The contents of polysaccharides were determined by phenol-sulfuric acid method and by reference to glucose, and wavelenth in spectrophotometer was set at 490 nm. RESULTS: There was difference of the content of the extracted polysaccharides among Glycyrrhiza for 1, 2 and 3 year, amounted to 11.75%, 11.07%, 7.88%, respectively. CONCLUSION: Annual glycyrrhiza appeared to be the appropriat crude drug for polysacchrides content. 1.Colle
