Fig. 1. Phylogenetic analysis of commercially available Radix Saposhnikoviae. Nine commercially available Saposhnikoviae Radix (B1–B3, S1–S3, and H1–H3) samples were purchased in Korea, and the authenticity of Saposhnikovia divaricate (Turxz.) was determined by phylogenetic analysis as described in Material and methods. H1–H3 show 100% similarity based on the Neighbor-Joining tree of cpDNA sequences of Saposhnikoviae species used in a subsequent experiment. 376 C.W. Kim et al.
