Peel and seeds are the main byproducts from tomato ( P. Mill) processing with high concentrations of polyphenols that have been underexploited. Herein, polyphenolic profiles in tomato peel and seeds were elucidated by untargeted liquid chromatography coupled to high-resolution mass spectrometry (LC-HRMS) with an LTQ Orbitrap analyzer. Samples from two Spanish regions─"Murcia" and "Almería"─were analyzed to obtain complementary results. 57 compounds were found, mainly phenolic acids and flavonoids, of which eight were identified for the first time in tomato. Polyphenols were more abundant in byproducts from "Murcia" samples than in those from"Almería" samples, where the abundance of compounds like coutaric, caffeic, neochlorogenic, dicaffeoylquinic and ferulic acids, vanillic acid hexoside, catechin, naringenin, prunin, apigenin--hexoside, rutin, and rutin--pentoside was even much higher in byproducts than that in whole fruits. These results reveal the wide range of polyphenols found in tomato byproducts, with potential applications in pharmaceutical research, food preservation, and cosmetic development, among others.
番茄皮和籽是番茄加工的主要副产品，其中含有高浓度的多酚，但尚未得到充分利用。在此，采用配有LTQ Orbitrap分析仪的非靶向液相色谱-高分辨率质谱联用仪（LC-HRMS）对番茄皮和籽中的多酚类物质进行了分析。分析了来自西班牙两个地区——“穆尔西亚”和“阿尔梅里亚”的样本，以获得补充结果。共发现57种化合物，主要是酚酸和黄酮类化合物，其中8种是首次在番茄中鉴定出来的。“穆尔西亚”样本的副产品中多酚含量比“阿尔梅里亚”样本的副产品中更高，在“阿尔梅里亚”样本的副产品中，香豆酸、咖啡酸、新绿原酸、二咖啡酰奎尼酸、阿魏酸、香草酸己糖苷、儿茶素、柚皮素、樱草素、芹菜素己糖苷、芦丁和芦丁戊糖苷等化合物的含量甚至比整个果实中的含量还要高得多。这些结果揭示了番茄副产品中存在的多种多酚，在药物研究、食品保鲜和化妆品开发等方面具有潜在应用价值。
