The extraction of hesperidin was investigated on a laboratory scale by varying the solvent composition and the solid-to-solvent ratio, and then scaling this process (volume: 20 L). Next, a purification process using adsorption resins was assessed: first through static tests to determine the ...
Objective:In order to obtain the optimal conditions for separating the alkaloids from the extract of Stemona japonica by selecting appropriate cation exchange resins.Methods:Seven types of cation exchange resins were evaluated in separating efficiency with measuring the adsorption ratio and eluting ratio ...
Applicant has isolated a Factor Xa inhibiting substance from the salivary gland extract of the leech H. ghilianii. The extract is subjected to separation using both DEAE-cellulose and heparin-agarose chromatography resins eluting with an increasing salt gradient. The extract is subjected to affinity...
PURPOSE:To extract and purify stevioside in a high recovery, by treating an extract of leaves of stevia with a water-soluble metal salt and ion exchange resins, and by treating the anion exchange resin with a water-soluble organic solvent. CONSTITUTION:An extract of leaves of Stevia rebaudiana...
