Omija seed oil was extracted from Omija seeds, a by-product of Omija, using an eco-friendly pressed extraction method. Physicochemical properties and antioxidant activities of 12 extracts using different combinations of seed moisture content (5, 7.5, and 10%) and extraction temperature (25, 49, 75, and 100℃) were then investigated. The highest extraction yield was 31.33% at moisture of 5% and temperature of 75℃. The lowest acid value was 4.18±0.25 at moisture of 5% and temperature of 49℃ or moisture of 7.5% and temperature of 25℃. Peroxide value, iodine value, and saponification value were the lowest at 0.64±0.56 meq/kg, 159.38± 6.03, and 57.60±9.40, respectively, at moisture of 5% and temperature of 25°C. The content of total polyphenolics was the highest at 4,413±125 mg TAE/100 g when the moisture content was 10% and the extraction temperature was 25℃. DPPH radical scavenging activities of oil extracts at 20~100 mg/mL were 28.68±7.30~87.65±2.20%. The maximum antioxidant activity and IC50 were 87.65±2.20% and <20 mg/mL, respectively, for extract obtained at moisture of 10% and temperature at 100℃. As a result, the extraction yield, acid value, peroxide value, iodine value, saponification value, and so on were excellent at moisture content of 5% and extraction temperature of 25℃ or 49℃. However, the content of total polyphenolic compounds and antioxidant activity were the highest at moisture of 10% and extraction temperature of 100℃. In conclusion, extracting Omija seed oil from Omija seeds, a by-product of Omija, is effective with a pressed extraction method.

The compositions of total and free amino acids in parts of Omija were investigated. The most abundant amino acids in fruits, endocarps, and seeds were arginine (50.80%), lysine (14.37%), glutamic acid (14.22%), respectively. Since the amino acid scores of fruits, endocarps, and seeds were 9.4, 11.9, and 16.7, respectively, the limiting amino acid of each part were S-compound amino acids. In the composition of free amino acids, contents of lysine were highest one such as 51.78, 57.00 and 32.88% in fruits, endocarps and seeds, respectively. The contents of histidine from free amino acids were 23.62% in fruits, 22.37% in endocarps, and 26.41% in seeds.

This study was carried out to investigate the compositions of free sugars, lipids, and nonvolatile organic acids in parts of omija. The major components of free sugars in each part of omija were fructose and glucose. The contents of those were similar in fruits and endocarps, however, the content of glucose was 1.5 times as much as that of fructose in seeds. The content of lipids in endocarps was 2.4 times as much as that in seeds, and major composition of lipids was neutral lipid. In the contents of nonvolatile organic acids, the content of citric acid that content was 61 to 68% depend on each part of sample was highest among other components, and that of malic acid being 25 to 30% was followed. The contents of nonvolatile organic acids of water extract were 74.5, 55.9, and 69.2% as high as those of original sample in fruits, endocarps, and seeds, respectively. The content of oxalic acid in seeds was lower than that of it in original sample.

This study was carried out to comparison of the contents of general and mineral components between the original sample and water extract in each part of omija. The content of Carbohydrate was highest in endocarps, and that the crude protein and crude lipid in seeds. The contents of K and Mn in the fruits, endocarps, and seeds were all higher than those of the other cations. The content of K and Zn in endocarps were three to four times as much as those of seeds. and the content of Na, Ca, and Cu in endocarps were 1.5 to 1.75 times of seeds. Mineral contents by water extract in each part were ordered as K, Mg, Ca, and Fe. As the percentage of each ion in water extract on the basis of original sample, Fe was the highest ratio of behavior, and Mn was lowest.

The influence of different roasting temperatures, times and extraction methods on the quality characteristics of Omija (Schizandra chinensis) seed oils was investigated. Roasted Omija seeds were divided into five groups based on roasting temperature-time conditions: no roasting (Raw) and roasting [R11: 150℃, 10 min, R12: 150℃, 20 min, R21: 250℃, 10 min, R22: 250℃, 20 min (R22)]. Oils from each of the raw and roasted Omija seeds were obtained by solvent (n-hexane) and press (machine) extraction. The L* values decreased, but the a* and b* values increased with increasing the roasting temperature and time. The L* values were lower in the press-extracted oils than in the solvent-extracted oils. The peroxide value (POV) of Omija seed oils decreased with increasing the roasting temperature-time values. The POV value was higher in the press-extracted oils than in the solvent-extracted oils. ABTS (2, 2＇-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid)) radical inhibition of Omija seed oils was higher in the solvent-extracted oils than in the press-extracted oils, but there were no significant differences between the two oils. The four major kinds of fatty acid methyl esters detected in Omija seed oils were methyl butyrate, methyl hexanoate, methyl arachidate, and methyl eicosanoate. In conclusion, Omija seed oils obtained by solvent extraction and at higher roasting temperature-time values were more effective antioxidants.
