Sulfur-containing components in an ethanol extract and boiled water extract of onion (Allium cepa L.) were analyzed by HPLC. Trans-(+)-S-propenyl-l-cysteine sulfoxide (PeCSO) and its γ-glutamyl peptide (γ-Glu-PeCSO) were the major constituents in the ethanol extract, whereas cycloalliin was the most abundant one in the boiled water extract. The large amount of cycloalliin found in the boiled water
通过HPLC分析乙醇(洋葱)的乙醇提取物和白开水提取物中的含硫成分。反式-(+)-S-丙烯基-1-半胱氨酸亚砜(PeCSO)及其γ-谷氨酰肽(γ-Glu-PeCSO)是乙醇提取物中的主要成分,而环丙氨酸是开水中含量最高的成分提炼。在开水提取物中发现的大量环丙氨酸主要是通过加热从五氯苯中获得的。通过在含有0.05%(w / v)的味精和次肌苷二钠的鲜味溶液中进行的感官测试,PeCSO和γ-Glu-PeCSO表现出特征性的浓厚风味(连续性,厚度和满口感)。
