The purpose of this research was the comparative study of 3 kinds of black soybean on murine immune cells. The 3 kinds of black soybean are Glycine max Merr. with inner color-yellow (GY), Glycine max Merr. with inner color-greenish (GG) and Rhynchosia volubilis Lour. (RV). All of the black soybean increased the viability of murine thymocytes in vitro. The combined treatment of GY or GG and mitogen did not affect the viability of splenic T- and B-lymphocytes compared with mitogen-treated group, but the combined treatment of RV and mitogen increased their action compared with mitogen-treated group. Also, the 3 kinds of black soybean were given p.o. once a day for 7 days, respectively. RV increased the population of thymic-$CD8^+$, splenic-$CD8^+$ and $B220^+$ cells in vivo. Furthermore, GY and GG did not affect the phagocytic activity and the production of nitric oxide in peritoneal macrophages in vitro, but RV enhanced their action. These results suggest that immunopotentiative action of Rhynchosia volubilis Lour. is more potent than their of Glycine max Merr.

본 연구에서는 노란콩과 검은콩의 메탄올 추출물과 각각의 콩으로부터 제조된 된장 메탄올 추출물이 IL-2, IL-6 및 TNF-${\alpha}$를 포함하는 사이토카인의 생성과 종양전이 억제에 미치는 영향에 대해 검토하였다. IL-2의 경우, LPS를 처리하지 않았을 때 대조군과 2개월 발효 검은콩 된장 메탄올 추출물 (10 ${\mu}g$/ml)에서 가장 높은 IL-2 생성을 나타내었고 LPS (1 ${\mu}g$/ml)를 처리한 후에는 검은콩 메탄올 추출물에서 가장 높은 IL-2 생성을 보였고 대조군에서 가장 낮은 생성을 나타내었다(p<0.05). 또한 IL-6 생성의 경우 LPS를 처리하지 않았을 때 2개월 발효 검은콩 된장 메탄올 추출물(10 ${\mu}g$/ml)에서 가장 높은 수치를 나타내었고 대조군과 2개월 발효된 노란콩 된장 메탄올 추출물(10 ${\mu}g$/ml)에서 가장 낮았다(p<0.05). LPS (1 ${\mu}g$/ml)를 처리한 경우, 대조군, 노란콩, 2개월 및 7개월 발효된 검은콩 메탄올 추출물(10 ${\mu}g$/ml)에서 검은콩 및 2개월 발효된 노란콩 된장 메탄올 추출물(10 ${\mu}g$/ml)에서 보다 유의적으로 높은 수치를 나타내었다(p<0.05). TNF-${\alpha}$의 생성에서 2개월 발효된 검은콩 메탄올 추출물(10 ${\mu}g$/ml)은 LPS를 처리하지 않을 때와 LPS (1 ${\mu}g$/ml)를 처리한 후 둘다의 경우 기타 실험군들에 비해 유의적으로 높은 TNF-${\alpha}$의 Journal of Life Science 2009, Vol. 19. No. 2 269 생성을 나타내었다(p<0.05). 한편 종양전이의 예방적 효과에 대한 실험결과에서 1 mg/mouse 농도로 투여하였을 때 2개월 발효된 노란콩 된장, 검은콩, 2개월 검은콩 된장, 7개월 검은콩 된장에서 각각 18%, 26%, 21%, 50%로 7개월 발효된 검은콩 된장에서 종양전이를 크게 억제하는 것으로 나타났다. 따라서 검은콩으로 제조한 된장은 사이토카인 생성을 증가시켜 면역증진 활성을 나타내었으며 암전이의 예방효과도 우수하였음을 확인할 수 있었다.

A series of aqueous extracts and residues from leaves, stems, roots, pods and seeds of Korean black soybean (Glycine max (L.) Merr.) were assayed against alfalfa (Medicago sativa) and barnyard grass (Echinochloa crus-galli) to determine their allelopathic activities through petri-dish and greenhouse experiments, and the results showed highest inhibition in the extracts or residues from the seeds, and followed by pods. The extracts of 40g dry tissue $\textrm{L}^{-1}$ applied on filter paper in petri-dish bioassay significantly inhibited root growth of alfalfa, and especially extracts from seeds and pods reduced root length of alfalfa more than those from leaves, stems, or roots. Plant height, root length, shoot and root dry weights of barnyard grass were reduced significantly by residue incorporation of seeds and pods as the incorporated amount increased. These results suggest that black soybean plants had herbicidal potential, and their activities were exhibited differently depending on plant parts.

Black root rot caused by Cylindrocladium crotalariae is one of the most serious soilborne disease in soybean. Plant height reduction of Hwangkeum Kong was 38% by the rotting of the whole main root and 9% by rotting of the half of the main root as compared with partial discoloration in the main root. Pod number per plant and seed weight were significantly reduced by the increase of the disease severity. Important yield components such as number of pods per plant and seed weight were negatively correlated with the soybean black root rot severity.

With the aim of developing region specialized crops, this study was conducted to clarify effects of variant and cultivation region on antioxidative activities in various black soybean (Glycine max L.) seed tissues. Three black soybean varieties (SCEL-1, Wonheug, and Cheongja 3) were each cultivated in 4 different regions (Jeonju, Pyeongchang, Paju, and Cheonan). Harvested seeds were used to assess DPPH and ABTS radical scavenging activity, and total polyphenol, flavonoid and anthocyanin content. SCEL-1 soybean hull contained higher DPPH and ABTS radical scavenging activity (61% and 85% respectively) compared to Wonheug (40% and 50% respectively). SCEL-1 cultivated in Pyeongchang displayed the highest total polyphenol and flavonoid content (1,189 mg GAE/100g sample and 951 mg CTE/ 100g sample, respectively). Total anthocyanin content was ranked in the following order: SCEL-1>Wonheug>Cheongja 3. All black soybeans showed much higher antioxidant activity in the soybean hull than in the dehulled soybean. The antioxidant activity of black soybeans cultivated at high latitudes was high. These results suggest that the best black soybean variant for high beneficial biological activities is the SCEL-1 variant. For a complete understanding of the potential of black soybean as functional foods, we plan to further analyze their antioxidant activities in future studies.

This study was aimed to investigate whether or not black soybean supplements affect levels of lipid profiles and female hormone (estradiol; E2, estrogen; Es) in 57 middle-aged women (in their 40s and 50s). All subjects were randomly assigned to the control or black soybean supplement group (BSS group). The BSS group was allocated to use dietary black soybean supplements (100 g/day) for 8 weeks. The BSS subjects were divided into two subgroups; 14 women were in the premenopausal group and 15 were in the postmenopausal group. We measured lipid profiles, female hormones and nutrient intakes at 0 weesk and 8 weeks. After 8 weeks, high-density lipoprotein (HDL) cholesterol was significantly decreased (P<0.01) and the athrogenic index (AI) was significantly increased (P<0.01) in control group. In BSS group, triglyceride (TG) (P<0.05), low-density lipoprotein (LDL) cholesterol (P<0.01) and LDL-HDL ratio (LHR) (P<0.01) were significantly decreased. However, E2 and Es were significantly increased (P<0.01). Compared to the control group, the BSS group revealed statistically significant improvements in the levels of TG, HDL-cholesterol, AI, LHR, E2 and Es (P<0.05). In the premenopausal group, HDL-cholesterol (P<0.05), E2 (P<0.01) and Es (P<0.05) were significantly increased and AI (P<0.01) and LHR (P<0.01) were significantly decreased after 8 weeks. In the postmenopausal group, E2 (P<0.05), and Es (P<0.05) were significantly decreased. However, total cholesterol (TC) was increased (P<0.01). Compared to the postmenopausal group, the premenopausal group was significantly improved on HDL-cholesterol, LDL-cholesterol and LHR (P<0.05). In conclusion, black soybean supplements may have beneficial effects on improving lipid profiles and female hormones.

We profiled the health-promoting bioactive components in nine types of soybean seeds with different seed coat colors (yellow, green, brown, and black) and investigated the effects of different extraction solvents (methanol, ethanol, and water) on their antioxidant activities. The carotenoid and anthocyanin compositions varied greatly by seed color, and the phenolic acids, total phenol, and total flavonoid contents differed by genotype. The carotenoid content was relatively higher in soybean seeds with green and black seed coats than in those with a yellow seed coat while lutein was the most plentiful. The anthocyanin content was considerably higher in the soybean seed with the black seed coat. The results of the DPPH assay showed strong antioxidative activities in the methanol- and water-extracts compared to the ethanol-extract, irrespective of the seed coat colors. Moreover, the soybean seeds with the black seed coat exhibited the highest antioxidant activity among the samples, regardless of the extraction solvent used. Eighteen bioactive compounds were subjected to data-mining processes including principal component analysis and hierarchical clustering analysis. Multivariate analyses showed that brown and black seeds were distinct from the yellow and green seeds in terms of the levels of carotenoids and anthocyanins, respectively. These results help our understanding of the compositional differences in the bioactive components among soybean seeds of various colors, providing valuable information for future breeding programs that seek to enhance the levels of compounds with health benefits.

Seoritae with green cotyledons refers to Korean native black beans harvested when the frost falls because the maturity is late. It is one of the beans preferred by consumers because of its softness and high sugar content. Because of late maturity, if the agricultural work is delayed by weather or agricultural schedule in green cotyledon black soybean (Seoritae), it affects seriously harvest and yield of soybeans. The aim of this study was to investigate the marginal seeding period on June 30, July 10 and July 20 in Cheongju and Jecheon area in Korea to produce stable soybean yield. The yields of green cotyledon black soybean as seeding date in Cheongju area are as follows: Seolitae (Yeoncheon), Seoltae (Goesan) and Seoritae (Gogseong), which increased by 23%, 56%, 23% and 40%, respectively, compare to July 10th to June 30th. As soybean sowing is delayed, the quality of soybean seeds has decreased due to the increase of immature seeds and fungal damaged seeds. The contents of anthocyanin in Cheongju area a functional substance of soybeans, was high on July 20 for Heukcheong, on June 30 for Seolitae (Yeoncheon), on July 10 for Seoritae (Goesan). The yields of Heukcheong and Seolitae (Yeoncheon) in Jecheon area were increased by 5% and 17%, respectively, compare to July 10th to June 30th, while Seolite (Goesan) and Seolite (Gogseong) were high in yields on June 30th. Similarly in Cheongju area, as the sowing period is delayed, the number of immature and mold damaged seeds in Jecheon area increased. The contents of anthocyanin in Jecheon area was high on July 10 for Heukcheong, on June 30 for Seolitae (Yeoncheon) and Seolitae (Goesan). From the above results, Sowing marginal date of green cotyledon black soybeans (Seolitae) in Cheongju area increased 30% in sowing on July 10 and increased 2% in sowing on July 20 compared to June 30. And Sowing marginal date of green cotyledon black soybeans (Seolitae) in Jecheon area increased 2% in July 10 compared to June 30, and the yield decreased rapidly on July 20. We have identified the seeding time limit of green cotyledon black bean in Chungbuk province. It will be possible to provide a variety of crop selection after double cropping of farmers. And by knowing the yield and seed quality of soybean according to sowing date, farmers will observe appropriate sowing period of soybeans for high quality. From the viewpoint of consumers, functional substances of Seoritae will meet the desire for health.
