Abstract:

Perilla species is a self-fertilizing annual plant belonging of the Lamiaceae family, subfamily Lamioideae that is widely cultivated and distributed in the Korea, China, and Japan. In Korea, perilla has been one of the most important oil crops and has been used as edible and industrial oil. Especially, Perilla frutescens is known as �??Dlggae�?� in Korea. The seed of perilla is source of oils produced and then used as a salad oil or cooking medium in Korea. Perilla seeds contain high levels of linolenic acid (�?-3), which can be expressed to possess various effects such asheart disease, high cholesterol, high blood pressure, and asthma. The linolenic acid exposed to air, oxidation and rancidity is advanced. The rancidity causes the unpleasant smell or taste, thus, the use of perilla is limited. Recently, studies for suppressing the rancidity are underway. Antioxidant component can be suppressed and a delay rancidity. In previous studies on perilla, antioxidants such as caffeic acid, ferulic acid, rosmarinic acid, luteolin and apigenin have been reported. So, in this study, we analyze the content of antioxidants in the perilla 21 cultivars using HPLC. An analysis of the antioxidant contents in the perilla cultivar seeds was performed using high-performance liquid chromatography.The total antioxidant contents was 0.336-1.708 mg�?�g-1,of which Daesil (1.708 mg�?�g-1) formed the highest amount, approximately five times of the lowest content (Areum, 2.195 mg�?�g-1). Thus, progression of rancidity of Daesil thought to be slower than the other perilla cultivars.
