The extract was concentrated under reduced pressure, and then dissolved in 30% ethanol to give 1 g/ml (crude medicine/volume) sample liquor, and then this liquor was passed through AB-8 macroporous resin column with 1 time the volume which was comparable to the weight of macroporous resin.
Dec 01, 2004· Extracting and purifying with macroporous resins was found to be an efficient potential method for the industrial production of mulberry anthocyanins as a food colorant. Of six resins tested, X-5 demonstrated the best adsorbent capability for mulberry anthocyanins (91 mg/mL resin).
FIELD: metallurgy. SUBSTANCE: proposed method comprises preparing leaching solution bearing gold, and gold sorption by macroporous resin containing alkyl amine functional groups in amount of 0.01-1.0 mmol/g and 3-12% of cross-links with water retaining capacity making, at least, 30%, and specific surface area varying from 400 to 1200 m 2 /g. After sorption, gold is eluted.
Isolation and purification of anthocyanins from black bean canning wastewater by column chromatography with macroporous resins were investigated in this study. Different adsorption materials and adsorption conditions were compared and the most
This study developed an efficient method to simultaneously separate and purify syringoside and oleuropein from Syringa oblata Lindl. extract using macroporous resins. The adsorption and desorption property of 11 resins were systematically evaluated. Based on the adsorption performance, HPD-100B resin was selected for the separation of syringoside and oleuropein.
