A total of 11 phenolic compounds, as well as sucrose (12) and tryptophan (13), were isolated from cold-pressed Perilla frutescens var. arguta seed flour using column chromatography, and their chemical structures were identified as 3'-dehydroxyl-rosmarinic acid-3-o-glucoside (1), rosmarinic acid-3-o-glucoside (2), rosmarinic acid (3), rosmarinic acid methyl ester (4), luteolin (5), luteolin-5-o-glucoside (6), apigenin (7), caffeic acid (8), caffeic acid-3-o-glucoside (9), vanillic acid (10) and cimidahurinine (11) using NMR and time-of-flight mass spectrometry. Of these components, compound 1 is novel, and this is the first report of compounds 10 and 11 in perilla seeds. HPLC quantification combined with antioxidant activity evaluation revealed that rosmarinic acid and rosmarinic acid-3-o-glucoside were the dominant phenolic antioxidants with strong antioxidant activities.
