This study aimed to determine microbiological quality on vegetable salad used dressing added with Prunus mume extracts. For this study, Dressing were blended with Prunus mume extracts to different concentrations of 0, 10, and 20%. Microbiological effects of vegetable salad used dressing added with Prunus mume extracts were assessed during production process by measuring process time, temperature, pH and Aw and determining total plate counts and coliforms. Effects of vegetable salad used dressing added with Prunus mume extracts on total plate counts and coliforms were observed during holding at 3, $25{\pm}1^{\circ}C$ for 12 hours. Dressing added with Prunus mume extracts improved the microbiological quality and showed antibacterial properties when they are added to vegetable salad.

To examine the free radical scavenging activities from buckwheat, Suwon No. 5 was extracted with various solvents. The seed of Suwon No. 5 had a high contents of carbohydrate, but the vegetable of that had a 31.4% of protein, 28.6% of ash and 25.7% carbohydrate as moisture free basis. Phenols contents of vegetable extracts had higher than those of seed extracts. Acetone extract of vegetable showed the greatest electron donating ability. Butanol and acetone extracts of vegetable showed high inhibitory effect on lipid peroxidation. Acetone extract of vegetable has also excellent activity in the superoxide radical scavenging activity by xanthine/xanthine oxidase-cytochrome c reduction system. The inhibitory effects of extracts on xanthine oxidase were measured. Acetone extract had the strongest inhibitory effect on xanthine oxidase and $IC_{50}$ was 2.2$\mu\textrm{g}$.

Ethanol extracts from 36 vegetable samples were assayed for their growth-promoting effects on Bifidobacterium bifidum, B. longum, and Lactobacillus casei The growth-promoting effects varied according to bacterial strain and vegetable species. In modified Gy rgy broth, extracts of Lactuca sativa, Lycopersicon esculentum and L escutentum var. cerasiforme exhibited strong growth-promoting responses toward B. longum, and significant and strong growth- promoting response toward B. bifidum was observed in extracts of Actinidia arguta, Allium cepa, A. sativum, Brassica campestris subsp. napus vats. pekinensis, Capsicum frutescens, Daucus carota var. sativa, L sativa, 1. esculentum and L. esculentum var. cerasforme, Nelumbo nucifera, Cucurbita moschata, Lackca sativa var. capitata, and Rubus coreanus. For L casei, extracts of A. fshlosum, A. hberosum, Cichorium intbus, Cucurbita moschat\ulcorner Ipomoea batatas, 1. sativa var. capitata, L. esculentum, P. brachycarpa, Raphanus sativus, R. coreanus, and S. melongena strongly enhanced the growth of this bacteria. In modified Gy rgy broth, the promoting effect was most pronounced with B. bifidum and L. casei among lactic acid bacteria used. In MRS broth, A. arguta, A. cepa, A. sativum, B. campestris subsp. napus var. pekinensis, C. frutescens, and D. carota var. sativa L. satiw var. capitata, and R. coreanus strongly enhanced the growth of B. bifidum, Growth of B. longum was strongly affected by the addition of extracts from L. sativa var. capitata. For L casei, moderate growth-promoting responses were observed in 9 vegetable extracts. The promoting effect in MRS broth was most pronounced with B. bifidum among lactic acid bacteria used.

일상 식생활에서 널리 섭취하고 있는 야채류를 사용하여 니트로사민의 직접적인 생성인자인 아질산염 분해작용에 관하여 검토하였는데, 그 결과를 요약하면 다음과 같다. 1. 마늘, 산초, 생강, 양파 및 파 둥은 수용성획분에서 당근은 methanol 가용성획분에서 각각 아질산염 분핵능이 높게 나타났다. 2. 반응용액의 pH변화에 따른 아질산염 분해능은 pH 1.2에서 가장 컸으며, pH가 증가할수록 분해능은 감소하였다. 3. 각 시료를 10mg씩 취하여 얻은 아질산염 분해능을 동량의 L-ascorbic acid와 비교한 경우, 마늘과 산초가 수용성획분에서 L-ascorbic acid와 거의 비슷한 분해능을 나타내었다. 4. 각 시료를 $NaBH_4$로 처리하여 환원능을 소실시킨 후에 측정한 아질산염 분해능은 pH 1.2에서 시료 모두 모두 그 값이 현저하게 감소하였다

There has been growing interest in the antioxidative and anticarcinogenic effects of vegetables. This study was aimed at evaluating the antioxidative and antiproliferative activities of 13 leafy vegetables consumed in Korea. New-beet and ornamental kale contained >1,000 mg of polyphenolics/100g fresh weight (FW), which was the greatest amount among the test vegetable extracts. Ornamental kale also contained the greatest amount (232.84 mg/100g FW) of flavonoids. With the exception of chicory, values of 1.1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radical scavenging activities showed similar trends. New-beet was found to be the greatest antioxidant among the test vegetable extracts. New-beet exhibited the highest antiproliferative activity (>60%) against all tumor cells. No relationship was found between antiproliferative activity and antioxidant contents or antioxidant activities among samples.

Ethanol extracts of 38 vegetables were subjected to an in vitro screening for their growth-inhibitory activities towards Bifidobacterium bifidum, B. longum, Clostridium perfringens, Lactobacillus acidophilus, L. casei, and Escherichia coli using paper disc agar diffusion methods under anaerobic conditions. The responses varied with both bacterial strain and vegetable species. In a test with 20 mg/disc, Zingiber officinale extracts showed significant growth-inhibitory responses against B. bifidum, and strong inhibitions against L. casei were detected in the extracts of Chrysanthemum coronarium var. spatiosum and Lactuca sativa. The extracts of Allium sativum, Capsicum annuum, L. esculentum, L. esculentum var. cerasiforme, and Z. officinale showed strong inhibitory activities against C. perfringens, while moderate growth-inhibitory responses were observed in the extracts of C. ffutescens, Cucurbita moschata, Daucus carota var. sativa, and Rubus coreanus. However, all vegetable extracts showed no inhibitions against B. longum, L. acidophilus, and E. coli. In tests with 5 mg/disc, moderate inhibitions were observed in the extracts of C. coronarium var. spatiosum and L. sativa against L. casei and Z. officinale against B. bifidum. Vegetables extracts, except for C. coronarium var. spatiosum, L. sativa, and Z. officinale, did not affect the growth of beneficial bacteria. Strong inhibitory responses against C. perfringens were detected in the extracts of C. annuum and L. esculentum var. cerasiforme. Daily intake of vegetables may be important in the prevention of human diseases caused by the intestinal bacteria.

본 연구에서는 흰점박이꽃무지 함유 음료의 총폴리페놀함량과 항산화활성(DPPH 라디칼 소거능, TRAP, ORAC assay, comet assay) 및 사용에 대한 안전성을 검증하기 위하여 ICR mouse를 사용하여 흰점박이꽃무지 무첨가군과 첨가군 단회 투여(2 g/kg) 시 나타나는 치사율, 체중, 생리적 증상, 장기무게, 생화학적 분석(triglyceride, total cholesterol, HDL-cholesterol, LDL-cholesterol, aspartate transaminase, alanine transaminase)을 통해 급성독성시험을 실시하였다. 흰점박이꽃무지를 함유한 호박, 알로에, 돼지감자음료 1 pack의 총 페놀함량은 66.35~100.98 mg/pack, DPPH 라디칼 소거능은 67.1~90.0%/1 pack, TRAP 값은 $1.46\sim1.54{\mu}M$/trolox equivalent(TE)를 보였으며, 모든 음료의 ORAC 값은 1500보다 높았다. 모든 음료는 인체 임파구에서 세포독성을 보이지 않았으며, $H_2O_2$에 대한 DNA 손상에 대한 보호효과는 유의적이었다. 흰점박이꽃무지 첨가/무첨가 음료의 ICR mouse 암수 각각에 경구투여(2 g/kg) 후 14일까지 치사된 실험동물은 관찰되지 않았으며, 체중, 생리적, 병리적 및 생화학적 분석에서 대조군과 비교 시 그룹들 간의 유의한 변화는 관찰되지 않았다. 그러므로 2 g/kg의 흰점박이꽃무지 첨가/무첨가 음료를 ICR mouse에 단일 경구투여시 독성이 없는 것으로 판명되었다. 본 연구에서 규명된 흰점박이꽃무지 함유 음료의 항산화활성과 안전성은 산업적측면에서 약용 및 식용 자원으로 적극적인 활용을 기대할 수 있을 것으로 사료된다.

Oxidation of low density lipoprotein (LDL) is regarded to play an important role in the development of atherosclerosis. In the present study, salad vegetables with a remarkable DPPH radical-scavenging activity were extracted with methanol, and the methanol extracts were evaluated for the inhibition of $Cu^{2+}$-induced oxidation of human LDL. Separately, the amount of total phenolics was determined colorimetrically using Folin-Ciocalteu reagent. The vegetable extracts, expressing a strong inhibition of LDL oxidation ($IC_{50}$ values, <$100\;{\mu}g/mL$), were from angelica, dandelion, mustard leaf, and water spinach, which contained relatively high level of polyphenol content. Noteworthy, a highly positive correlation was observed between inhibition of LDL oxidation and amount of total polyphenol (p<0.01). Based on these results, it is suggested that salad vegetables, especially angelica, dandelion, and mustard leaf, may be used as easily accessible sources of natural antioxidants, especially in anti-atherosclerosis.
