Abstract: The effective extraction method for total saponins from the roots of Codonopsis lanceolata was investigated. With codonolasides as reference compounds, the amount of total saponins were analyzed by high performance liquid chromatography with solid-phase extraction (SPE-HPLC). The maximal amount of total saponins was obtained when the roots were refluxed with 30-fold amount of 70% ethanol in 60 min by extracting 3 times.

Key words: Codonopsis lanceolata, optimized extraction method, total saponins
