“…The contents of the extracted isoflavone aglycones in seeds of the investigated soybeans were unlikely to be identical with previous studies (Moon et al 1996;Hong et al 2010b). Based on results of Seguin et al (2004) and Morrisona et al (2010), which drought stress closely related to decrease of isoflavone content, we assumed that severe diminution of precipitation in all two regions, Suwon and Yeoncheon, plays a critical role in the decrease of aglycones in seeds of the investigated soybeans.…”

We conducted this study to select useful germplasms for investigating the agricultural performances and content variations of proximate composition, fatty acid, and isoflavone of the soybean germplasms grown at two different latitudes, Suwon (37 o 16'N) and Yeoncheon (38 o 12'N), Republic of Korea. The days to flowering of the soybeans grown at Suwon was early by 1 day compared with that at Yeoncheon whereas the days to maturing of the soybeans were not different by latitudes. The Yeoncheon-cultivated soybeans were greater in growth and yield than the Suwon. The crude oil in range of 17.0% to 20.0% had a positive correlation with the yield. There was a strong negative correlation between oleic acid and saturated fatty (palmitic and stearic) acid contents in the seeds producted at Suwon but the Yeoncheon were not significant. The linoleic acid in seeds of the germplasms was contained by 7.3-fold more than the linolenic acid. The malonylgenistin content was the highest among the detected isoflavones and Deapung had the highest total isoflavone content. The content of total isoflavones in the Yeoncheon-producted seeds was high more than that in the Suwon whereas those of Hei nong 44(hou), Tachikogane, and B152 grown at Suwon were significantly lower rather than those at Yeoncheon. However, the difference of latitude seemed to play an important role in the content variations of growth, yield, and fatty acids and isoflavones in the germplasms. Eventually, Tie dou 44 and WIR3722, which were stably outstanding in all the investigated aspects regardless of the growing locations, were selected as useful germplasms.

“…The differences between HBK and HBC cell viabilities may have been due to differences between the geographical location and soil environments of the HBs. The plant's phytochemical content may vary in the composition depending on the environment [ 23 24 ]. Also, the HBs used in this study were not representative of their respective sources.…”

BACKGROUND/OBJECTIVESThe honeysuckle berry (HB) contains ascorbic acid and phenolic components, especially anthocyanins, flavonoids, and low-molecular-weight phenolic acids. In order to examine the potential of HB as a hepatoprotective medicinal food, we evaluated the in vitro anti-oxidant and anti-inflammatory activities of Korean HB (HBK) and Chinese HB (HBC).MATERIALS/METHODSAntioxidant and anti-inflammatory effects of the extracts were examined in HepG2 and RAW 264.7 cells, respectively. The anti-oxidant capacity was determined by DPPH, SOD, CAT, and ARE luciferase activities. The production of nitric oxide (NO) as an inflammatory marker was also evaluated. The Nrf2-mediated mRNA levels of heme oxygenase-1 (HO-1), NAD(P)H dehydrogenase [quinone] 1 (Nqo1), and glutamate-cysteine ligase catalytic subunit (Gclc) were measured. The concentrations of HB extracts used were 3, 10, 30, 100, and 300 µg/mL.RESULTSThe radical scavenging activity of all HB extracts increased in a concentration-dependent manner (P < 0.01 or P < 0.05). SOD (P < 0.05) and CAT (P < 0.01) activities were increased by treatment with 300 µg/mL of each HB extract, when compared to those in the control. NO production was observed in cells pretreated with 100 or 300 µg/mL of HBC and HBK (P < 0.01). Treatment with 300 µg/mL of HBC significantly increased Nqo1 (P < 0.01) and Gclc (P < 0.05) mRNA levels compared to those in the control. Treatment with 300 µg/mL of HBK (P < 0.05) and HBC (P < 0.01) also significantly increased the HO-1 mRNA level compared to that in the control.CONCLUSIONSThus, the Korean and Chinese HBs were found to possess favorable in vitro anti-oxidant and anti-inflammatory activities. Nrf2 and its related anti-oxidant genes were associated with both anti-oxidant and anti-inflammatory activities in HB-treated cells. Further studies are needed to confirm these in vivo effects.

Mutation through radiation can be used in soybean breeding to generate the plant genetic variability. Some mutant promising lines of black-seeded soybean have been selected, namely PA-3-PSJ, A-5-PSJ, A-7-PSJ, and B-4-PAIR and it is essential to study their quality for soy sauce preparation. Detam 1 and Mutiara 3 were used as variety checks. The results showed that all soybean lines belonged to large-seeded with the largest seed obtained in A-7-PSJ line (17.41g/100-grain), while Detam 1 and Mutiara 3 had smaller seed sizes than those of four lines. Conversely, both varieties had the highest protein contents (38.56-39.36% dw), followed by A-7-PSJ (37.79% dw), whereas the rest had lower contents. A considerable increase in protein content was observed in the koji, which about 88% to 93% existed as soluble protein. The protein contents of soy sauce were slightly different, ranging from 2.35% to 2.57% (dw). Detam 1 showed the highest score for color, aroma, taste and viscosity of soy sauce preferences, followed by B-4-PAIR and Mutiara 3 that had the same score and A-7-PSJ, which also gave the highest protein content and had the largest seed size. This suggests that B-4-PAIR and A-7-PSJ lines are promising for ingredients of soy sauce.
