Purpose: Lycium ruthenicum Murr. is a nutritional food that has been used widely for treatment of heart disease, abnormal menstruation, and menopause. Methods: In this study, the crude protein, crude lipid and crude ash contents of two different Lycii fruits with different colors were investigated, and their color values, total sugar, pH, total anthocyanins and total carotenoids were analyzed. Results: Regarding crude ash, crude fat and crude protein contents, the L. barbarum showed higher in crude fat and crude protein contents than black fruits, whereas L. ruthenicum showed higher contents than black fruits. Regarding mineral composition, mineral contents were in the other of K, Mg, Mn, Na, Zn, and Fe. The K content was high in all of the samples, and the contents of Cr and Cu were not measured. The pH values of L. ruthenicum and L. barbarum were $5.00{\pm}0.01$ and $5.08{\pm}0.02$, respectively. The total sugar content of L. ruthenicum was 45.45% while that of L. barbarum was 45.43%. Ascorbic acid content of L. barbarum was $50.86{\pm}3.63%$ while that of L. ruthenicum was $6.3{\pm}1.40%$. The total anthocyanin content of L. ruthenicum was $462.22{\pm}0.41mg/100g$, although no anthocyanin was detected in L. barbarum. The total carotenoids content was $812.25{\pm}6.01mg/100g$ in L. barbarum, although that of L. ruthenicum was not measured. Conclusion: The results from this study indicate that there is a large difference in the composition of functional ingredients of L. ruthenicum and L. barbarum. There is a strong possibility of L. ruthenicum to be developed into color food sources.

Soybean (Glycine max L. (Merr) is commonly consumed and found in major foods including soymilk, soy sauce, tofu, and soy sprout in Korea and east Asia. In addition, it is common to cook the whole seeds with rice. Soybean is known to have ranges of health benefits including antiaging, anticancer, neuroprotective and antidiabetic taken either as supplement or dietary food. Anthocyanins and flavonoids in G. max are found to be the main contributors to such wide arrays of health benefits. Due to increasing economic values of soybean, development of specialty soybean cultivars is becoming an area of interest worldwide. In this study, 746 black soybean accessions from National Agrobiodiversity Center were characterized as part of an attempt to identify important germplasms of G. max. Seed coats of each accession were analyzed for their total anthocyanin, cyanidin 3-O-Glucoside (C-3-O-G), delphinidin 3-O-glucoside (D-3-O-G), petunidin-3-O-glucoside (Pt-3-O-G), and their whole seeds for crude protein contents. HPLC was used to determine and quantify the anthocyanin compositions while crude protein was determined using Kjeldahl method by Kjeltec auto-analyzer (Kjeltec 8400, Foss, Sweden). Accessions were grouped according to their anthocyanins and protein contents; the mean content of which were correlated to agronomic traits including maturity date, one hundred seed weight, cotyledon color and seed lust color. The results indicated that the total anthocyanin content (TAC) ranged from 273.77 to 6250.52 mg/100 g, with mean value of 1853.03 mg/100 g while the crude protein content (CPC) being between 33.43 and 47.51%, with mean value of 40.81%. The highest number of accessions (45.97%) showed TAC between 1000~1900 mg/100 g while 30.96% of accessions showed CPC between 41~43%. Among the 746 accessions considered, 11 (IT142935, 175818, 175855, 177191, 177209, 177211, 177214, 177216, 177218, 177220, 177274) of them showed TAC above 4000 mg/100 g. C-3-O-G was found to be the major contributor to TAC showing strong correlation. Accessions with green cotyledon color showed high mean TAC compared to those having yellow cotyledon color, and accessions with dull seed lust color showed high mean TAC than those having shiny seed lust color. One hundred seeds weight and maturity date showed positive correlation with all anthocyanin contents, except for Pt-3-O-G in the latter case. The overall result of the present study could be used as background for developing new black soybean cultivars and breeds with high anthocyanin and protein contents. The result depicted that many of the accessions could be used as potential parental lines.

In sustainable viticulture, green manure represents a safe and non-polluting way to bring large quantities of organic matter into the soil. The cultivation of green manure crops plays an important role in soil quality and sustainability of agricultural system. This study was conducted to evaluate the effects of green manure fertilization on yield and quality of the Campbell Early grape variety in the organic vineyard. Hairy vetch was the more productive green manure crop, yielding higher dry materials. Average yields of grape were significantly greater in hairy vetch+rye ($13.02ton\;ha^{-1}$) than nature weed ($11.65ton\;ha^{-1}$), respectively. The concentrations of total as well as individual anthocyanins were consistently higher with hairy vetch treatment compared with rye and nature weed, thus making the green manure cultivation is an environmentally friendly cultivation to increase the yield and anthocyanin contents in organic grape.

Background and objective: Aronia melanocarpa, called black chokeberry, is a natural product belonging to the family rosaceae, and is known to contain polyphenolic antioxidants including cyanidin-3-galactoside, cyanidin-3-arabinoside, cyanidin-3-xyloside, and cyanidin-3-glucoside Because of the abundance of anthocyanins, Aronia has been studied to be used in various industries. Methods: Aronia melanocarpa extract was treated 24 hours a day to RAW 264.7 cells with inflammations induced by LPS. After extracting total RNA, the amount of inflammatory cytokine expression was measured using RT-PCR. After processing the Aronia liposome using Aronia extract and the layer-by-layer electrostatic deposition method in keratinocyte cells at the same time, we checked the synthesis of Hyaluronic acid enhanced through the formation of Aronia liposome using ELISA. Results: The treatment of Aronia extract in inflammation-induced RAW 264.7 cells conducted to check the anti-inflammatory efficacy of Aronia extract inhibited inflammatory cytokines including TLR4, TNF-α, IL-1β, COX-2, and iNOS and increased the mRNA expression of HAS2 genes related to moisturizing. Based on the anti-inflammatory and moisturizing effect of Aronia extract, the Aronia liposome technology was introduced to Aronia extract to produce Aronia liposome. Conclusion: The liposome formation of Aronia extract is expected to be used as a functional material in treating various inflammatory skin diseases by controlling the moisture content of the corneocytes by increasing the expression rate of genes associated with the synthesis of hyaluronic acid, while retaining the efficacy of its components.

기능성 옥수수 수염을 가지는 옥수수 계통을 선발하기 위해 다양한 자식계통과 F1을 대상으로 옥수수 수염의 항산화 성분과 항산화능을 측정하였다. 측정결과, 총 페놀 함량, 총 플라보노이드 함량의 경우 각각 980${\sim}$2,420 mg 100 $g^{-1}$, 1,532${\sim}$3,274 mg 100 $g^{-1}$의 범위를 나타내었다. 안토시아닌의 고유영역인 517 nm에서의 흡광도는 0.05에서 0.76까지의 범위를 보였다. 옥수수 수염의 항산화 성분과 DPPH, ABTS, FRAP assay에서 얻어진 항산화능간의 상관관계를 분석한 결과, ABTS와 FRAP assay에서 옥수수 수염의 항산화 활성과 페놀성물질 및 안토시아닌간의 상관계수가 유의하게 높았다. 옥수수 수염의 안토시아닌을 추출하는 용매가 산성이라는 점과 안토시아닌의 DPPH 용액과의 가시영역 파장에서의 간섭을 고려할 때, DPPH 보다는 ABTS assay나 FRAP assay가 더 적합한 항산화능 측정 방법이 될 것이다. 이들 중 특히 ABTS assay는 옥수수 수염의 주요한 기능성 성분인 안토시아닌과 플라보노이드 및 페놀성 물질과 모두 높은 상관성을 보여 옥수수 수염의 종합적인 항산화능을 평가하고 우수 계통을 선발하는데 적합한 측정 방법이 될 것으로 사료된다. 본 실험에서 안토시아닌 함량과 페놀 함량이 높고 ABTS assay와 FRAP assay에서 모두 높은 항산화능을 보여준 S15은 고 기능성 품종 육종 및 옥수수 수염을 이용한 기능성 소재 개발에 이용될 수 있을 것이다. 또한 옥수수 수염의 항산화능 측정에 대한 항산화 실험의 적합성 연구는 우수한 옥수수 수염을 선발하는데 도움이 될 것이다.
