Abstract: Anthrone-sulfuric method was used to determine content of polysaccharide in garlic seed and the conditions of colour reaction of anthrone-sulfuric method were optimized. The experimental results showed that the RSD in accuracy experiment is 2.10%, and the average recovery rate is 113% with RSD=1.17% (n=3).The method is rapid, accurate, sensitive and suitable for general analysis.
