Objective:To compare the content of crude polysaccharides from different tissues of Aconitum carmichaeli in different harvest time. Method: The content of crude polysaccharides was determined by sulfuric-phenol method

crude polysaccharides content from different tissues of A. carmichaeli in different harvest timewas compared

including mother root

sub-root

fibrous root

stem and leaves. Result: The content of crude polysaccharides in different tissues of A. carmichaeli were in the sequence of sub-roots>mother roots>fibrous roots>leaves>stems

the content of crude polysaccharides from aboveground part was less than underground part

the content of crude polysaccharides in sub-roots on June 4 was the highest

the content of crude polysaccharides in leaves and stems and fibrous roots on June 18 were more than other harvest period

the content of crude polysaccharides of in mother roots was the same on June 18 and July 3. Conclusion: This study was a preliminary exploration of dynamic variation about crude polysaccharides content from various tissues of A. carmichaeli

it could provide a scientific basis for comprehensive utilization of A. carmichaeli resources.
