Preparative isolation and purification of geniposide from gardenia fruits by centrifugal partition chromatography
2007
Kim, C.Y. | Kim, J. (Jinchoon)
The iridoid glycoside, geniposide was purified by centrifugal partition chromatography (CPC) with a two-phase solvent system composed of ethyl acetate:isopropanol:water (3:2:5, v/v) from an 80% methanolic extract of fruits of Gardenia jasminoides. Preparative CPC yielded 56.2 mg of geniposide in a one-step separation of 500 mg of extract, with a purity of 95% as determined by HPLC. Isolated geniposide was identified from its ¹H-NMR, ¹³C-NMR and MS spectra.
