Optimum Harvesting Time of Codonopsis pilosula Nannf.var.Modesta(Nannf.)L.T.Shen

The optimal harvesting time of Codonopsis pilosula Nannf.var.Modesta(Nannf.)L.T.Shen was confirmed.The optimal harvesting time of Codonopsis pilosula Nannf.var.Modesta(Nannf.)L.T.Shen was confirmed though study on different mouths yields and dynamic changes of total saponin amount for the biennial,three Codonopsis pilosula Nannf.var.Modesta(Nannf.)L.T.Shen.There was significant differences(p0.05) between yields of biennial,three Codonopsis pilosula Nannf.var.Modesta(Nannf.)L.T.Shen.Total saponin content in the period were no significant differences between(p0.05).Anova analysis showed that the total saponin content in different months in the same period there were significant differences between(p0.01).The yield,the total saponin content and the amount of active ingredient synthetically considered to determine the best harvest time of the cultivation in the third year from September to November.
