To determine the bioactive compound of domestic cherry tomato, the levels of lycopene, β-carotene, and phenolic compounds were analyzed in three domestic cherry tomato cultivars (Summerking, Qutiquti, and Minchal) using HPLC and LC-MS/MS. The levels of lycopene were 69.40 mg/100 g (Qutiquti), 69.07 mg/100 g (Minichal), and 38.52 mg/100 g (Summerking). The contents of β-carotene were 3.35 mg/100 g (Qutiquti), 2.30 mg/100 g (Summerking), and 2.25 mg/100 g (Minichal). Five phenolic compounds were identified exactly as 3-caffeoylquinic acid, 5-caffeoylquinic acid, quercetin-3-apiosylrutinoside, quercetin-3-rutinoside, and naringenin chalcone from three domestic cherry tomatoes. Five phenolic compounds were identified partially as two isomers of caffeic acid-hexose, caffeoylquinic acid isomer, di-caffeoylquinic acid, and tri-caffeoylquinic acid from three domestic cherry tomatoes. Naringenin chalcone was the most abundant phenolic compound, ranging from 78.2 mg/100 g for Qutiquti to 222.9 mg/100 g for Summerking. High levels of quercetin-3-rutinoside and 5-caffeoylquinic acid were found, ranging 24.3-50.8 mg/100 g and 31.8-47.6 mg/100 g, respectively. These results suggested that domestic cherry tomatoes can be used as bioactive food materials.
