Objective: To determine the total polysaccharides in different growth phase and different years of Puerariae lobatae Radix. Method: Total polysaccharides content was also determined by pheno-sulfuric acid method using dextrose as standard sample. Result: Glucose was linear in the range of 0.020-0.142 mg (r=0.999 9). The average recovery rate was 99.34% (RSD 1.82%). The content of total polysaccharides appeared regular changes and the content of total polysaccharides was highest in August and September of perennial Puerariae Lobatae Radix. Conclusion: The result might provide scientific basis for havesting of Puerariae Lobatae Radix.
