    摘要： POLYFRUCTOSAN TRINICOTINATES ARE DISCLOSED WHEREIN THE POLYFRUCTOSAN IS INULIN, SINISTRIN OR GARLIC POLYFRUCTOSAN. THESE MATERIALS MAY BE PREPARED BY ESTERIFYING NICOTINIC ACID OR A DERIVATIVE THEREOF WITH THE CORRSPONDING FRUCTOSAN IN THE PRESENCE OF AN ACID BONDING AGENT AND IN THE PRESENCE OF INERT SOLVENTS. THE RESULTING POLYFRUCTOSAN TRINICOTINATES HAVE PHARMACOLOGICAL ACTIVITY AND SLOWLY RELEASE NICOTINIC ACID IN THE BODY.

    摘要： METHOD FOR PRODUCING FRUCTOSE AND GLUCOSE FROM A MIXTURE THEREOF IN A MINERAL ACID-FREE AQUEOUS SOLUTION. WATER IS EVAPORATED FROM SAID SOLUTION AT A TEMPERATURE BETWEEN 50* C. AND 120*C. A LOW BOILING POINT ALCOHOL IS ADDED TO SAID SOLUTION, AND GLUCOSE AND FRUCTOSE THEN PRECIPITATED. THE WATER CONTENT OF SAID SOLUTION IS NOT GREATER THAN 1% WHEN FRUSTOSE IS PRECIPITATED THEREFROM. THE INVENTION ALSO INCLUDES A METHOD OF PEPARING SAID MIXTURE IN SAID SOLUTION FROM SUCROSE BY CONVERSION THEREOF TO INVERT SUGAR.
