In this study, fruit phenolics were investigated with using LC/MS and HPLC analysis in order to compare the differences between domestic (‘Campbell Early’, ‘Kyoho’, ‘Heukbosuk’, and ‘Hongju SDS’) and imported (‘Crimson SDS’ and ‘Thomson SDS’) grapes. In the case of fruit characteristics, imported grape ‘Crimson SDS’ and ‘Thompson SDS’, had lighter skin weight (300-350 mg/berry) and hard flesh (5.2-5.6 kg·f) than domestic grape cultivar. The phenolic compound contents of ‘Crimson SDS’ skin was higher, but resveratrol (25-29 mg/kg), quercetin (350-380 mg/kg), and myricetin (31- 32 mg/kg) contents were similar in to those of ‘Hongju SDS’. The anthocyanin content was different from differed between grape cultivars. ‘Hongju SDS’ grape was showed higher in Delphinidin-3-glucose (D3G) levels, and ‘Crimson SDS’ was showed higher in Peonidin-3-glucoside (P3G) levels. The contents of phenolic compounds were investigated differently for each grape berry part. Catechin, epicatechin, procyanidin B1, and B2 were found in grape seeds.
