title: Enrichment and purification of gardenia yellow from Gardenia jasminoides var. radicans Makino by column chromatography technique.
abstract: In present study, the performance and separation characteristics of nine macroporous resins for the enrichment and purification of gardenia yellow from Gardenia jasminoides var. radicans Makino have been evaluated. The adsorption and desorption properties of crude gardenia yellow solution on macroporous resins including HPD722, HPD100, HPD100A, HPD400, HPD400A, D101, AB-8, XAD-16, and NKA-9 have been compared. Then, HPD722 was chosen to purify gardenia yellow because of its strong adsorption and desorption abilities as well as high selectivity. Column packed with HPD722 resin was used to perform dynamic adsorption and desorption tests to optimize the separation process of gardenia yellow. The optimal conditions were as follows: The crude gardenia yellow solution with concentration of 15 mg/mL was loaded in column packed with HPD722 resin at the flow rate of 1.0 mL/min, and the adsorbate-laden column was washed with 800 mL water, 600 mL 15% ethanol water solution respectively at the speed of 2.5 mL/min, then desorbed with 200 mL 80% ethanol water solution at the speed of 3.5 mL/min. The colority of the product obtained were up to 300. The method developed in this study provides a new approach for scale-up separation and purification of gardenia yellow from G. jasminoides var. radicans Makino.
