METHODS: Using the methods of cluster analysis and according to the examination method ruled in the 2005 version 〈The People's Republic of China Prarmacopoeia〉,the content of total saponin in Platycodon grandiflorum in different harvest time was compared. RESULTS: Platycodon grandifloeum(Jacq.) A.DC and Platycodongrandifloeum(Jacq.) A.DC.var.Hort respectively on September 20,September 30 are the largest yield and the largest content of total saponin in root,that time is the best harvest time.
