Separation and purification of both tea seed polysaccharide and saponin from camellia cake extract using macroporous resin

A novel method to separate and purify tea seed polysaccharide and tea seed saponin from camellia cake extract by macroporous resin was developed. Among four kinds of resins (AB‐8, NKA‐9, XDA‐6, and D4020) tested, AB‐8 macroporous resin possessed optimal separating capacity for the two substances and thus was selected for the separation, in which deionized water was used to elute tea seed polysaccharide, 0.25% NaOH solution to remove the undesired pigments, and 90% ethanol to elute tea seed saponin. Further dynamic adsorption/desorption experiments on AB‐8 resin‐based column chromatography were conducted to obtain the optimal parameters. Under optimal dynamic adsorption and desorption conditions, 18.7 and 11.8% yield of tea seed polysaccharide and tea seed saponin were obtained with purities of 89.2 and 96.0%, respectively. The developed method provides a potential approach for the large‐scale production of tea seed polysaccharide and tea seed saponin from camellia cake.     

An efficient approach for enrichment of three isochlorogenic acids from Kuding tea using MCI-GEL resin

Kuding tea are used as a traditional tea material and widely consumed in China. Isochlorogenic acids are considered to be one of the major functional ingredients. In this study, nine types of resins including six macroporous resins and three MCI-GEL resins were investigated by adsorption and desorption tests toward the isochlorogenic acids. The HP50SS was selected as the optimal one and the effect of several factors were investigated to make optimization of the adsorption and desorption conditions for enrichment of isochlorogenic acids. As a result, 38.50?mg of refined extract including 31.70?mg total isochlorogenic acids could be separated and enriched from 500.0?mg of crude extract in which the content of total isochlorogenic acids was 8.6% and the recovery of isochlorogenic acids reached 73.4%. Meanwhile, under optimal dynamic adsorption and desorption conditions, the final contents of total isochlorogenic acids increased 9.3-fold when compared to that of crude extract in a scale-up enriched experiment. The results demonstrated that the HP50SS MCI-GEL resin was suitable for purification and enrichment of isochlorogenic acids from Kuding tea. The established protocol was high-efficiency, low-cost and environment-friendly, which could afford a potential approach for industrial applications to enrich and concentrate isochlorogenic acids from Kuding tea.

RECOVERY OF p-AMINOPHENOL （PAP） FROM AQUEOUS SOLUTION BY HYPER-CROSS-LINKED RESIN AND ITS USE FOR WASTEWATER TREATMENT

p-Aminophenol （PAP）, a typical amphoteric compound, has been widely used as raw chemical material and important interrnediate in various fields. To study on the recovery of PAP, an experimental comparison of the adsorption and desorption properties of PAP onto three types of hyper-cross-linked resins in aqueous solutions was performed. This paper focuses on the static equilibrium adsorption and desorption behaviors, the adsorption thermodynamics, the column dynamic adsorption and desorption, and other influencing factors of adsorption, such as temperature and pH values. All the isothermal data fit well to the Freundlich model. The capacity of equilibrium adsorption for PAP on NG-10 is the highest within the temperature range 288K-318K, which may greatly contribute to the advantage in specific surface area, especially the micropore area, of the adsorbent. While in the desorption experiments, NG-9 achieved relative well regeneration efficiency whether by ethanol or by 4% hydrochloric acid. Furthermore, the results of column tests and field applications were also proved that NG-9 was an effective sorbent for the reclamation PAP from wastewater.
