The sugars were extracted from the samples with water by ultrasonic oscillation. The sugar extracts were purified by solid phase extraction with Sep-Pak-C 18 cartridge. The sucrose, glucose and fructose were separated on a Waters Sugar-Pak-Ⅰ cation ion exchange column (6.5×300 mm) with 0.05g/L EDTA calcium disodium salt solution as mobile phase, and detected with a refractive index detector system.

The pectin in tobacco was hydrolyzed to galacturonic with hydrochloric acid. Then the galacturonic were separated on a Waters Sugar-Pak-Ⅰ(6.5×300mm) cation ion exchange column,with 0.05g/L EDTA calcium disodium salt solution as mobile phase and a refractive index detector system.
The sugars,glycerol,propylene glycol and xylitol in tobacco sauce were separated on a Waters Suger-Pak-I cations ion exchange column (6.5×300mm),with 0.05g/L EDTA calcium disodium salt solution as mobile phase and detected with a refract ive index detector system, and determined by high performance liquid chromatogra phy (HPLC).
EDTA Calcium disodium Salt is a useful anti-oxidant of foods, detoxica- ting agent and complexing agent. Therefore this paper studied the development of- EDTA calcium disodium salt. The producing process and condition preparing- EDTA calcium disodium salt by the application of shell, calcium hydroxide and EDTA are studied emphatically at the same time.
A high performance liquid chromatographic method for the determination of sugars, glycerol and propylene glycol in tobacco sauce was studied. Tobacco sauce was diluted with water and purified by solid phase extraction with Sep Pak C 18 cartridge. Sugars, glycerol and propylene glycol were separated on a Waters Sugar Pak I(6.5×300 mm) cations ion exchange column, with 0.05 g/L EDTA calcium disodium salt solution as mobile phase and a refractive index detector system. Oligomer sugar...
A high performance liquid chromatography(HPLC) method for the determination of sugar,glycerol and ethanol in ratafee was studied.Ratafee was preseparated by solid phase extraction with Sep Pak C 18 column.Sugars,glycerol and ethanol were separated on a Waters Sugar Pak Ⅰ(6.5?mm×300?mm) cations ion exchange column,with a refractive index detector system and 0.05?g/L EDTA calcium disodium salt solution as mobile phase.Sucrose,glucose,fructose,glycerol and ethanol could be simultaneo...
