Alcoholic fatty liver disorder has become a frequent health concern worldwide. To investigate the effects of Brassica oleracea (B. oleracea) sprout extract (BOE), the present study was designed with alcoholic fatty liver in the rat. Initially, the effects of BOE on liver parameters were examined. Male rats were divided into five groups. The normal control group was fed the normal diet, and the BOE group was fed the high fat diet and ethanol with/without BOE for 4 weeks. After 4 weeks feeding period, rats were sacrificed and their livers and blood were used for fatty liver-related biomarkers analyses. As a result, BOE ameliorated fatty liver-related enzymes profiles in liver tissues and also reduced blood alcohol concentration in rat model. We demonstrated that BOE protected the high fat diet and alcohol-induced fatty liver in rat model. Furthermore, BOE increased detoxificative abilities against alcohol.

Background: Brassica oleracea var. italica (broccoli), a rich source of antioxidants, can prevent various diseases and improve human health. In this study, we investigated the antioxidative effects of broccoli sprout extract on oxidative stress induced by lipopolysaccharide and cisplatin in cell and organ tissue models. Methods: Antioxidative effect of BSE was evaluated using DPPH and ABTS in RAW 364.7 cells, and effects of BSE on testes were investigated using Cisplatin-induced testicular damage model with an in vitro organ culture system. Results: The DPPH assay showed that the antioxidant activity of the alcoholic broccoli sprout extract was higher than that of the water extract. Additionally, the expression levels of antioxidation-related genes, Nrf2, Gsr, HO-1, and catalase, were significantly increased in broccoli sprout extract-treated RAW 264.7 cells, and the extract suppressed lipopolysaccharide-induced mitochondrial dysfunction. Based on the results in the RAW 264.7 cell culture, the antioxidative effects of the extracts were investigated in a mouse testis fragment culture. The expression of Nrf2, HO-1, and Ddx4 was clearly decreased in cisplatin-treated mouse testis fragments and not in both broccoli sprout extract- and cisplatin-treated mouse testis fragments. In addition, the oxidative marker O-HdG was strongly detected in cisplatin-treated mouse testis fragments, and these signals were reduced by broccoli sprout extract treatment. Conclusions: The results of this study show that broccoli sprout extracts could serve as potential nutraceutical agents as they possess antioxidant effects in the testes.

Brassica oleracea var. italica (broccoli) is a type of cabbage that contains vitamins, minerals, and phytochemicals. Consequently, it is used as a potential nutraceutical source for improving human health by reducing oxidative stress and inflammatory responses. Here, the effects of broccoli sprout extract (BSE) on the inflammatory response were investigated through lipopolysaccharide (LPS)-induced inflammatory mouse models. First, we found that the BSE obviously reduce NO production in RAW 264.7 cells in response to LPS stimulation in in vitro study. Pretreatment with BSE administration improved sperm motility and testicular cell survivability in LPS-induced endotoxemic mice. Additionally, BSE treatment decreased the levels of the pro-inflammatory cytokines TNF-a, IL-1β, and IL-6, and COX-2 in testis of LPS-induced endotoxemic mice models. In conclusion, BSE could be a potential nutraceutical for preventing the excessive immune related infertility.

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.

In order to examine the functionality of broccoli sprout (Brassica oleracea, BS), solvent extracts were prepared and their anti-oxidative and immunomodulating activities were compared with those of broccoli (B). EtOH extracts (E) were potently higher than hot-water extracts (HW) in the antioxidant contents and radical scavenging activity. In particular, the total polyphenolic contents in addition to ABTS and DPPH radical scavenging activity were significantly higher in EtOH extract of broccoli sprout (BS-E; 9.15 mg GAE/g, 4.52 mg AEAC/g, and 1.14 mg AEAC/g) compared with that of broccoli (B-E; 7.83 mg GAE/g, 3.63 mg AEAC/g, and 0.97 mg/AEAC/g). Whereas, total flavonoid content was significantly higher in B-E (1.60 mg QE/g) than BS-E (1.43 mg QE/g). Anti-inflammatory activity was investigated using LPS-induced cell line model at a concentration of $10{\sim}100{\mu}g/mL$, in which all solvent extracts of both broccoli sprouts and broccoli were not toxic to RAW 264.7 cell lines. In anti-inflammatory activity of broccoli sprouts, EtOH extracts also showed significantly more potent activity than hot-water extracts in all sample concentrations tested. In addition, BS-E ($100{\mu}g/mL$) inhibited nitric oxide (NO) and IL-6 production to 60.9% and 68.9% compared with the LPS inflammation group (without extracts), whereas B-E inhibited 49.6% and 54.9%. On the other hand, in immunostimulating activity by splenocytes and macrophages, hot-water extract showed significantly higher activity than EtOH extract. Especially, BS-HW stimulated the splenocyte proliferation (1.2-fold against saline group) and IFN-${\gamma}$ production (264.39 pg/mL) at $100{\mu}g/mL$, and the production of IL-6 (1.33-fold), IL-12 (1.09-fold) and TNF-${\alpha}$ (1.49-fold) from macrophages was also significantly enhanced over broccoli. In conclusion, broccoli sprouts showed more potent anti-oxidative, anti-inflammatory and immunostimulating activity than broccoli, suggesting the possibility of using broccoli sprouts as functional food materials.

십자화과 채소인 콜라비 및 무에는 glucosinolate 성분이 함유되어 있으며, 특히 새싹 채소의 경우 성숙한 채소보다 glucosinolate의 함량이 더 높은 것으로 알려져 있다. 이와 같은 이유로 최근 새싹채소에 대한 관심은 높으나, 아직 새싹채소에 대한 연구는 미비한 편이다. 따라서 본 연구에서는 십자화과 채소인 콜라비 새싹 추출물(KSE) 및 무순 추출물(RSE)의 total carotenoid 및 glucosinolate의 함량을 분석하였고 이들 추출물의 항산화 및 anti-adipogenic 활성을 평가하였다. KSE의 total carotenoid 및 glucosinolate 함량은 각각 $39.50{\pm}0.67$ 및 $2.65{\pm}0.02mg/g$이며, RSE의 total carotenoid 및 glucosinolate 함량은 각각 $76.73{\pm}2.75$ 및 $8.13{\pm}0.54mg/g$으로 KSE보다 높았다. 다양한 항산화 평가 모델(DPPH, ABTS, FRAP, reducing power)을 통하여 항산화 활성을 측정한 결과, KSE 및 RSE는 농도 의존적으로 항산화 활성이 증가하는 경향을 나타내었다. 또한, 지방세포의 분화과정에서 KSE 및 RSE의 처리는 지방세포의 지방축적 및 ROS 생성을 억제하였으며, KSE 및 RSE의 주요 성분으로 알려진 ${\beta}$-carotene, glucoraphanin 및 glucoraphenin의 처리는 지방 축적 억제 및 ROS 생성 저감 활성을 나타내었다. 이상의 결과로부터, ${\beta}$-carotene, glucoraphanin 및 glucoraphenin이 풍부한 RSE 및 KSE는 항산화 활성 및 지방세포 분화억제 효능을 갖으며, 천연물 유래 항비만 소재로서 활용 가능성이 높은 것으로 기대된다.
