Abstract
In order to determine the contents of trans-resveratrol in red wine, which was mainly consumed in Korea, both LC/MS-ESI and LC/MS-APCI methods were used after solid-phase (Sep-Pak <TEX>$C_{18}$</TEX>-cartridges) extraction. The contents of trans-resveratrol obtained by LC/MS-ESI were detected in the range of <TEX>$0.06-4.31{\mu}g/mL$</TEX>. The recoveries were ranged from 88.4 to 97.9%. The values of relative standard deviation were ranged from 0.6 to 4.6% and the detection limit was <TEX>$0.001{\mu}g/mL$</TEX>. The contents of trans-resveratrol obtained by LC/MS-APCI were detected in the range of <TEX>$0.09-4.02{\mu}g/mL$</TEX> and the detection limit was <TEX>$0.005{\mu}g/mL$</TEX>.
