Embodiment 1
[0148] Example 1 - Separation of Bioactive Compounds from Acrylic Polymer Adsorbents
[0149] A glass column with an internal diameter of 40mm and a height of 540mm, equipped with a PTFE piston, packed with a 350mm high nonionic ethylene glycol cross-linked polymethyl methacrylate adsorbent polymer resin (CAS 25777- 18-5) (Alimentech P495 inert adsorption polymer supplied by the company Bucher Foodtech). The resin has a bed volume of 400 ml with a column interstitial dead volume of 180 ml. Prior to use, the acrylic polymer sorbent is typically washed with 10 bed volumes of water.
[0150] Three 250ml aliquots of OPE (750ml total) were applied on top of the column containing the acrylic polymer sorbent and each aliquot was permeated down through the column at a rate of 4ml / min. At this speed, each aliquot takes approximately one hour to elute through the column. After applying OPE, the column was washed with two 250ml aliquots of water.

[0180] Example 2 - Separation of biologically active compounds from an anion exchange resin column
[0181] A diameter is 2cm, the column that length is 20cm is filled with 200mm high weak base anion exchange resin (Diaion WA-30 resin provided by Supelco company, its average particle diameter is 0.47mm, and total exchange capacity is 1.5meq / mL). The bed volume of the resin was 50 mL. Before use, the anion exchange resin (WA-30) was successively washed with 0.5M sodium hydroxide solution of 2 times of bed volume (100mL), water of 5 times of bed volume (250mL), 0.5M hydrochloric acid solution of 2 times of bed volume and 5 times the bed volume of water to condition it. The final wash water has a pH of 4.2.
[0182] Fraction 8 and Fraction 9 obtained in Example 1 were processed to further purify the limonoid glucosides in these fractions. These fractions, with an alcohol content of 30% and 40% respectively, contain a higher proportion of limonoid glucosides.

Embodiment 3
[0192] Example 3 - Method for recovery of bioactive compounds from orange peel extract (OPE)
[0193] A method for the isolation of bioactive compounds from orange peel extract (OPE) is described. The method uses the following 4 separation columns:
[0194] Column A: This column is a glass column with an internal diameter of 40 mm and a height of 540 mm fitted with a Teflon stopcock. It was partially filled with 200 mm high acrylic resin (Alimentech P495 inert absorbent polymer supplied by Bucher Foodtech). The resin has a bed volume of 250 mL, with a column interstitial dead volume of 110 mL.
[0195] Column B: This column is a glass column with an internal diameter of 23 mm and a height of 180 mm fitted with a Teflon plunger. It is partially filled with 180mm high polystyrene-divinylbenzene resin (AmberliteXAD-16 provided by Sigma-Aldrich, which has a surface area of 800m 2 / g, the average pore diameter is 100 Angstroms). The bed volume of the resin was 50 mL.
