Abstract The simultaneous determination of sugar and nicotine with high performance liquid chromatography (HPLC) in tobacco was studied. The sugar and nicotine was extracted from the tobacco samples by ultrasonic oscillation for 30 min with 45 ml of 5％ acetic acid solution. Then, the extract was purified by solid extraction with a Waters Sep-Pak-C18 cartridge. The sugars and nicotine were separated on a Waters Sugar-Pak-1 (6.5×300 mm) cations ion exchange column with 0.05 g.L-1 EDTA calcium disodium salt solution as mobile phase. The sugar was detected with a refractive index detector and the nicotine was detected with an UV detector. The detection limit reachs m g/ml level for sugar and ng/ml level for nicotine. The recoveries of sugars and nicotine were between 97- 102 %. The relative standard derivations of sugars and nicotine were 1.3-2.2%. This method was applied to the determination of Sugars and nicotine in tobacco with good result. |
