This study was to investigate the chemical composition and biological activities of P. Koraiensis seed. The oil, moisture, ash, crude protein, and carbohydrate contents of P. Koraiensis seed were 58.21, 7.84, 1.56, 14.26, and 18.13%, respectively. The ratios of essential amino acid and nonessential amino acid against total amino acids were 36.6 and 60.3%, respectively. The saponification value of seed oil was 166.8 mg KOH/g oil. Among various fatty acids, the linoleic acid content was the highest, 35.5%, which was approximately 72.6% of polyunsaturated fatty acid. The ethylacetate extract of P. Koraiensis seed had the highest DPPH radical scavenging activity (62.8%) at 7.0 mg/mL, followed by hexane extract, methanol extract, and hot water extract. The maximum nitrite scavenging activity was obtained 59.3% at pH 1.2. The total phenolic concentration of ethylacetate extract was 98.7 mg/g, approximately 4.8 folds higher than that of the hot water extract. The maximum inhibition activities of elastase using ethylacetate extract and collagenase using hexane extract were 58.8 and 40.7%, respectively. These results indicate that P. koraiensis seed extract could be applied to present the possibilities of industrial applications for the developments of cosmetics.
