| Zusammenfassung: | THE PRESENT INVENTION RELATES TO A METHOD FOR PREPARATION OF POTASSIUM HYDROXYCITRATE. THE METHOD COMPRISING THE STEPS OF FIRST, PROVIDING A DRIED PLANT MATERIAL. SECOND, EXTRACTING THE PLANT MATERIAL USING METHANOL AT A REFLUX TEMPERATURE AND COLLECTING THE EXTRACT. THIRD, REPEATING STEP TWO AN ADDITIONAL TWO TIMES. FOURTH, COMBINING THE THREE EXTRACTS OF STEPS TWO AND THREE. FIFTH, ADDING ACTIVATED CHARCOAL TO THE COMBINED EXTRACTS WHILE STIRRING. SIXTH, FILTERING THE COMBINED EXTRACTS AND OBTAINING CLEAR FILTRATE. SEVENTH, TREATING THE CLEAR FILTRATE WITH METHANOLIC POTASSIUM HYDROXIDE AT PH GREATER THAN PH 10 AND REFLUXING FOR THREE HOURS TO PRECIPITATE POTASSIUM HYDROXYCITRATE. EIGHTH, FILTERING THE PRECIPITATE. NINTH, WASHING WITH METHANOL AND TENTH, DRYING UNDER VACUUM. MOST ILLUSTRATIVE |
