Eggplant (Solanum melongena L.) is an excellent source of vitamin A and C as well as flavonoid compounds, which are important antioxidant components that may reduce the risk of diseases. In this study, we investigated ABTS, DPPH activity and flavonoid contents in eggplant leaves and fruits to identify genetic resources with high antioxidant capacity for use in food or as feed additives. A total of 102 eggplant accessions were classified into four groups by latitude of their origins: 0°~15° N (8 accessions), 15°~30° N (19 accessions), 30°~45° N (34 accessions), and 45°~60° N (41 accessions). The accessions originated from 45°~60°N showed the highest flavonoid contents (AVG. = 15.4 μg mg-1) followed by accessions originated from 30°~45° N (AVG. = 13.0 μg mg-1), 15°~30°N (AVG. = 11.0 μg mg-1) and 0°~15°N (AVG. = 9.5 μg mg-1). Same pattern was also found in ABTS and DPPH antioxidant activities. High ABTS, DPPH activity and flavonoid contents were found in the early-flowering accessions. All flavonoids of the greenish violet leaves were significantly higher than those in green leaves. The flavonoid concentration in eggplant leaves with an average of 15.6 μg mg-1 increased from 10- to 20-fold as compared with their fruit (AVG.=0.9 μg mg-1). In conclusion, eggplant leaves represent a potential source of natural antioxidants due to their very high flavonoid contents.

This study investigated saponin contents according to collection area, seed size and seed color in 293 Korean soybean landraces. Results showed that total group A was 149.8 to 1279.0㎍/g with an average of 484.9㎍/g while total group B saponin content was 2160.1 to 7868㎍/g with an average of 3670㎍/g. Total groups A and B saponin content were ranging from 2502.7 to 8763.9㎍/g with an average of 4154.8㎍/g. The landraces with high group B saponin content were IT226841, IT226761, IT226844 and IT226826. The landraces with low group A saponin content were IT228580, IT228319, IT228308 and IT226841. According to collection areas, the highest amount of saponin content was observed in the landraces collected from North Korea. High total of saponin content was showed by seeds from Gyeonggi-do, followed by Chungcheongbuk-do, Gangwon-do, Gyongsangbuk-do, Chungcheongnam-do Jeollabuk-do and Jeollanam-do. According to seed size, small seeds have the higest saponin contentfollowed by the medium and large size of seeds. For seed color, there was no significant difference in saponin content. The total of saponin content was postively correlated with group A saponin, group B saponin and total of saponin cntent. Among each components, group A saponin showed postive correlations with total of saponin and group B saponin content.

This study was conducted to examine the variations of seed hull color characteristics, the oil contents and fatty acid composition in 275 sunflower germplasms. The seed hull of sunflower germplasms were classified into 4 colors of white, black, grey, and brown. The grey color of seed hull was the highest percentage of 33.8%, whereas the white color of seed hull was the lowest percentage of 5%. Average oil content was 22.5% with a range from 11.7% to 45.5%. Average saturated fatty acid contents were 6.9%, while average content of unsaturated fatty acid was 93%. The average contents of fatty acids such as palmitic acid, stearic acid, oleic acid, and linoleic acid were 4.7%, 2.2%, 55.2%, and 38%, respectively. Comparing the oil contents and fatty acids among different seed hull colors, the highest content of oil was with grey seed hull color and the lowest with white seed hull color. Saturated fatty acid were higher in brown seed hull color. Unsaturated fatty acids were higher in grey and black seed hull colors. It could be observed that there was significant negative correlation(r=-0.998**) between linoleic and oleic acid content, and also L-value(Lightness of seed hull color) showed significant negative correlations with oil content, oleic acid content and linoleic acid content.
