The applicability of Brussels sprouts, which are widely cultivated in Jeju, as a functional biomaterial in the cosmetics and food industries is investigated. The active ingredients (total phenols and flavonoids, β-carotene, vitamin C, free sugar, minerals, glucosinolates, and isothiocyanates) and antioxidant activities of 70% ethanol extracts of Brussels sprouts and cabbage were analyzed. The total phenol, flavonoid, vitamin C, and β-carotene contents of Brussels sprouts were approximately 36%, 2.5 times, 2.3 times, and 65% higher than those of cabbage, respectively. The total free sugar content of Brussels sprouts was 58%-72% lower than that of cabbage. The K content was the highest among the other minerals, and there was little difference between the two samples. The Na content was approximately three times higher in cabbage than in Brussels sprouts. The total glucosinolate content of Brussels sprouts was 34.5 mol SE/g DW, twice that of cabbage. The sinigrin content of Brussels sprouts was thrice (10.06 μmol/g DW) that of cabbage. The isothiocyanate (sulforaphane, I3C) content in Brussels sprouts was double that of cabbage. The antioxidant activity of Brussels sprout extract was 2.5 to 2.8 times higher in 1,1-Diphenyl-2-picrylhydrazyl radical scavenging capacity and 3.3 to 3.6 times higher in 2,2'-Azino-bis(3-ethybenzothiazoline-6-sulfonic acid) radical scavenging capacity than those of cabbage extract. These are important basic data for the study of glucosinolates and isothiocyanates, which have anticancer activity, as well as antioxidant-related substances of Brussels sprout, which has high potential for use as a biomaterial in functional foods and cosmetics.

This paper was conducted to examine the effect of Brussels Sprouts Extract on the inhibition of pro-inflammatory cytokines. The inflammatory response is manifested by mediators such as reactive oxygen species and inflammatory cytokines such as TNF-α, IL-1β, and IL-8. Therefore, this paper examined the toxicity to cells using the MTS assay, stimulated RAW264.7 macrophages with lipopolysaccharide (LPS), and stimulated reactive oxygen species such as NO and TNF-α, IL-1β, and IL-8. Inhibition of inflammatory cytokines after treatment with 10 mg/mL, 100 mg/mL, and 1000 mg/mL of Brussels Sprouts Extract was investigated. As a result of the experiment, Brussels Sprouts Extract inhibited NO production, TNF-α and IL-8 in a concentration-dependent manner without cytotoxicity, and showed significant inhibition especially at a concentration of 1000 mg/mL. Brussels Sprouts Extract, which inhibits the production of inflammatory cytokines, suggests the possibility of reducing inflammatory response and controlling inflammation, and can be seen as providing potential as a health functional food or prevention and treatment of inflammation.

방울다다기양배추는 아직까지 국내에서는 소비자들에게 인지도가 낮은 작물이지만 최근 식생활 및 소비 패턴이 변화하면서 편의성, 차별성 등이 중요시면서 미니 과일, 미니채소류에 대한 관심이 증가하고 있다. 또한 외국의 도입 채소류에 대한 관심이 증가하면서 2013년 방울다다기양배추 수입량이 36톤이었던 것이 2015년에는 14.3배가 증가한 515톤으로 증가하였다. 이를 통해 방울다다기양배추가 가지고 있는 기능성과 미니채소에 대한 관심으로 지속적으로 소비가 증가할것으로 예상되고 있다. 이와같이 증가추세에 있는 방울다다기양배추의 수입을 대체하기 위해서는 국내 재배면적 확대가 필요하나 저온성 작물인 방울다다기양배추는 고온기 남부지역에서는 재배가 어려워 제주지역의 겨울재배 작형으로 제한되어 재배가 되고 있다. 따라서 제주지역의 겨울재배 작형과 연계하여 강원도 고랭지의 서늘한 여름 기후를 이용하여 단경기인 9~11월에 생산할 수 있는 여름재배 작형을 개발할 필요성이 있어 시험을 수행하였다. 본 시험은 2018년~2019년 태백 철암의 노지(표고 750 m)에서 시험품종은 "브릴리언트"를 이용하여 3월 하순 파종하여 50일 육묘하여 5월 10일 포장에 정식하였다. 흑색멀칭한 시험포장에 $80{\times}30cm$부터 $80{\times}60cm$까지 10 cm 간격으로 차이를 두고 정식하였으며 정식 전 N-P-K = 20-15-20 kg/10 a를 시비하였고 시험포장은 수확까지 병해충 방제 등 주기적으로 관리하면서 생육특성 및 수량성을 조사하였다. 재식거리별 생육상황을 비교한 결과 초장은 처리간 큰 차이가 없었고 경경은 재식거리가 커질수록 증가하는 경향이었다. 또한 엽장 및 엽폭은 처리간의 경향이 없었으며 엽수는 재식거리가 커질수록 증가하였고 $80{\times}30cm$ 처리시 80매내외였던 것이 $80{\times}50cm$ 이상일 경우 100매 이상으로 증가하였다. 재식거리별 구의 특성을 조사한 결과 구경은 처리간 큰 차이는 없었으나 재식거리가 커질수록 구경이 다소 증가하였으며 구중도 증가하는 경향이었다. 방울다다기양배추의 구의 엽수는 처리간 큰 차이가 없었고 경도 및 당도도 큰 차이가 없었다. 처리별 수량은 $80{\times}40cm$와 $80{\times}50cm$ 처리에서 수량이 다소 증가하였고 상품화율은 $80{\times}50{\sim}60cm$ 처리에서 80%이상으로 높았다. 따라서 방울다다기양배추의 여름 고랭지 재배시 재식거리는 $80{\times}50cm$ 처리시 생육 및 엽수 증가에 따른 구의 형성이 증가하여 수량성이 높아지고 상품화율도 증가하였다.

Incidence of Fusarium wilt was surveyed in fields of summer radish in Gangwon province in Korea in 2018 and 2019. The disease started in early July and spread rapidly in hot summer of late July and August and in severe case, reached up to 80% in a field in Gangneung area. Symptoms in the seedling stage include poor growth and browning of internal tissue of root. During mid-growth, the leaves of diseased plant turned yellow over time, the surface of the roots changed from white to blackish, and the vascular tissues turned brown. A total of 23 isolates was obtained from the diseased plants and identified as Fusarium oxysporum f. sp. raphani by elongation factor-1α and intergenic spacer sequence analysis. Pathogenicity of the isolates was tested by artificial inoculation to the radish and other plants. All the isolates tested were pathogenic to radish plant, although there were differences in virulence on radish 11 cultivars. However, the isolates were not virulent to other plants except some cruciferous vegetables including Brussels sprouts, rocket, stock, and turnip. The results of pathogenicity test showed that it is necessary to rotate with crops other than cruciferous vegetables in order to prevent Fusarium wilt from radish fields.

This study was performed to investigate the effects of vegetable sprout powder on serum and adipose tissue lipid metabolism in rats fed high-fat diet for 4 weeks for induction hyperlipidemic model rat. Weight-matched male Sprague-Dawley rats were assigned to five groups according to dietary fat level (10% or 20% of diet wt.) and mixture of vegetable sprout powder levels (5% or 10% 10% or 20% of diet wt.). Vegetable sprout powder was the mixture of same amounts of dried barley, broccoli, rapeseed, alfalfa, radish, mustard, buckwheat and brussels sprouts. Experimental groups were normal fat diet with 5% cellulose (NF-C), high fat diet without fiber (HF-N), high fat diet with 5% cellulose (HF-C), HF-C diet with 5% vegetable sprout powder (HF-CSL), and HF-C diet with 10% vegetable sprout powder (HF-CSH). The body weight of HF-N group increased 16% compared with the NF-C group, while it was decreased by 15% and 22% for HF-CSL group and HF-CSH group, respectively. Fat mass and fat cell size of adipose tissue were lower in HF-CSL group and HF-CSH group compared with HF-C group, and lower in HF-CSH group compared with HF-CSL group. Serum triglyceride, total cholesterol and LDL-cholesterol contents were markedly decreased by vegetable sprout powder containing diet, while the serum HDL-cholesterol and phospholipid contents were higher in vegetable sprout powder containing diet in a dose-dependent manner. Leptin and insulin levels in serum showed a decrease in HF-CSH group. Significantly increased contents of triglyceride, total cholesterol, LDL-cholesterol, leptin and insulin in the serum of HF-N group were returned to normal or even below normal levels by feeding 10% vegetable sprout powder diet. The increased activities of NADP-malate dehydrogenase (ME), glucose-6-phosphate dehydrogenase (G6PDH) and 6-phosphogluconate dehydrogenase (6PGDH) and lipoprotein lipase (LPL) in adiposetissue by HF-N group were decreased to the activity of normal fat group by feeding vegetable sprout powder in a dose-dependant manner. These results indicate that lipid metabolism in rats fed high-fat diet was suppressed by feeding vegetable sprout powder.
