  • We investigated the effects of bean sprouts (Glycine max), dropwort (Oenanthe javanica), and radish (Raphanus sativus var. hortensis for. acanthiformis) extracts on alcohol dehydrogenase (ADH). The extracts from three kinds of vegetables were prepared by extracting with boiling water, distilling water, and ethyl alcohol. Among extracts, boiling water extract showed the highest activating effect on ADH, respectively and distilled water extract had a greater effect on ADH activation than that of alcohol extract. The ADH facilitating effect of bean sprout extract by distilled water was significantly higher than dropwort or radish, hut the effect of the bean sprout extract by ethyl alcohol was lower than others. The facilitating effect on ADH of mixture extracts of bean sprout and dropwort were mixed at 1 : 1 mixture of boiled-water extract showed the highest effectiveness. And bean sprout extract separated below 3000 molecular weight (MW) range of extract fraction had greater ADH activity than large MW parts.

  • This experiment was planned to develop a functional supplements by food resources to prevent and lessen the bad effects caused by the environmental pollution such as bad food, air, water and heavy metals exposed to people these days. As for Its primary stage, the nutrient profile and sensory characteristics of the duck-extract were evaluated in this study. The duck-extract was formulated by the mixture of bone and internal organs of ducks and 6 medicinal herbs which were able to be used as foods and known to help the excretion and the repression of the poison inside the body for a long time. As we compared the six medicinal herbs mentioned above to the vegetable herbs, the nutrient profile of the medicinal herbs were superior to the vegetable herbs. The duck-extract was composed of protein 49.92%, carbohydrate 37.02%, dietary fiber 20.99%, lipid 7.60% and ash 5.46%. The ratio of Ca to P was 1 : 1.4, which was a suitable ratio for absorption, the contents of Na and K were low and those of micro-elements such as Fe, Mn, Zn and Cu high compared to other meat extracts. The essential amino acids accounted for 30.91% of total amino acids. The result of sensory evaluation was better in overall preferences than the ones which are already in the market. From these results, the nutrient profile of the duck-extract was estimated to be able to supply enough nutrients to the people whose nutritional balance was destroyed these days. This study also showed the effective way of using duck-extract and its application to the oriental medicine.

  • Potential antimutagenic activities of vegetable plants were investigated. 24 vegetables which are frequently consumed by Korean people were extracted with 70% ethyl alcohol to prepare the extract samples. Then those samples were added to the culture media containing mitomycin C($O.3\;{\mu}g/ml$) and the SOS-Chromotest was performed. Positive control, mitomycin C alone, showed about 330 units of ${\beta}$-galactosidase activities. Among 24 vegetable samples, Saxifraga oblougifolia Nakai (취나물, Saxifragaceae) and Platycodon grandiflorum A. De Candolle(도라지, Campanulaceae) showed 136 and 155 units, respectively when mitomycin C was treated. These results indicate that Saxifragae Herba and Platycodi Radix possess protecting action from mutagenic activity produced by mitomycin C.

It has a long history for Korean Women‘s grooming on the nail to be reddened, Actually those were very easy to gather and easy to extract the colors from the leaves and the flowers, Also Impatient Balsamina were abundant near our environment. So this was a cue as a natural dye for the wool fabric, This study was designed to testify the possibility of the Impatient Balsamina as a natural vegetable. First, 2 kinds of extracts from the Impatient Balsamina were prepared. Second, 2 kinds of mordants and 3 kinds of dyeing process were used. And the dyed wool fabric were evaluated the color index using Chroma Meter, the result was recorded as L$^*$, a$^*$, b$^*$ value(65.86, 16.40, 36.80). The effect of the mordants was more effective in Cr mordant than Al mordant in the color fastness and the color affinity. The very interesting results were in the colorfastness to the drycleaning, that was graded 4 to 5, but the colorfastness to light was low, graded 2. Impatient Balsamina was veryfied, it could be a natural vegetable dye for the wool fabric.

  • The effect of various vegetables commonly consumed by Koreans on the induction of glutathione S-trasferase(GST) activity in mice was assessd. The extract of vegetable dissolved in propylene glycol (5ml/kg body wt.) was administered to ICR female mice 6 to 8 weeks old via gavage during 5 days. The changes of body weight and liver weight of all treated groups were not significantly different compared with control group. Hepatic protein contents of trated groups compared with control group were not significantly different except BHT treated group. The induction of GST activity in liver cytosol of mice was the greatest with broccoli, followed by radish, wild green onion, turnip, and green onion. The induction of GST activity in liver cytosol increased up to 1.5 to 1.8-folds at a dose of 24 g fresh vegetable/mouse. The induction of combination between vegetables was the highest with the combination of broccoli and radish (1.83-fold), followed by that of broccoli and green onion (1.72-fold), and that of broccoli and turnip (1.50-fold).

  • In the present study, we assessed the effecs of fruit and vegetable bark resources rich in beneficial substances on the learning ability and memory improvement. It functions to inhibit the activity of acetylcholinesterase in brain tissue and improve cognitive functions in a simulation model of cognitive impairment induced by scopolamine. Hence, it can promote memory and learning ability. The formulation of the fruit and vegetable bark uses the extract of fruit and vegetable peels, which has long been used without causing toxicity in a wide range of food applications. Therefore, it can be used safely without a risk of side effects, even in the case of a long-term administration for the preventive purpose. Furthermore, the present study is a very beneficial study in the environment-friendly aspect in association with recycling of resources as it is based on the novel efficacies of fruit and vegetable barks which have been conventionally disposed as a refuse of fruits due to their poor sensory qualities despite the content of beneficial substances.

  • We collected rat feces by group period after oral administration of fructooligosaccharides and fruit and vegetable complex extracts for 2 weeks in the Sprague-Dawley rat model of loperamide-induced constipation and analyzed trends in changes in the intestinal microbiome. Microbial composition analysis was performed on Fractoologosaccharide and fruit and vegetable complex extracs(FVCE), by 16S rDNA cloning and pyrosequencing to obtain basic data for the standardization and systematization of the FVCE manufacturing process. Microbial analysis of the prokaryotic community revealed a slight difference in microbial verrucomicrobiota was dominant at the phylum level. At the genus level, prevotella and muribaculaceae showed further differences at the species level. These results suggest that the microbial community used affects the quality of fruit and vegetable complex extracs(FVCE) produced. Thus, a stable microbial community must be maintained for the production of fruit and vegetable complex extracs(FVCE) with consistent quality.

  • This study was performed to measure the mutagenicity of fish by cooking and storage. Mutagenicity of the fish extract was measured by Ames test(Salmonella typhimurium reversion assay with TA 100) in vitro and by micro-nucleus test in vivo. The fish samples screened in this study were white fish(Trichiurus, Croaker, Salted Croaker) and red fish(Saury pike, Mackerel, Yellowtail, Salmon). The number of revertants of red fish were significantly higher than that of white fish. And the mutagenicity of mackerel was higher than other red fish, so followed experiment was made by using the extract of mackerel. Mutagenicity of the samples cooked on microwave oven was the lowest, whereas there was no significant difference between the samples cooked on gas grill and the ones on electric grill. In the presence of S9 mixture, the methanol extract of mackerel showed 2∼4 times high values of mutagenicity in comparison with the extract without S9. The extract of mackerel cooked with various vegetable juices showed inhibitory effects on the mutagenicity in the order of green tea, ginger, and radish. Also, the number of revertants was increased in the stored samples. Mutagenicity of the samples stored in the refrigerator was higher than that of the freezer. In micronucleus test, the methanol extract treated with vegetable juice inhibited micro-nucleus formation in bone marrow by cyclophosphamide in the order of ginger, green tea, and radish. In TBA test, there was a tendency that TBA values were increased as the storage time increased. Also, the rancidity of sample were stored in the refrigerator was higher value than sample stored in the freezer. Samples cooked on microwave oven showed the highest value in rancidity. When the antioxidant effect of vegetable juice was measured by electron donating ability(EDA) of mackerel cooked with vegetable juice to DPPH, the samples treated with onion showed the highest value of EDA(%), and the samples treated with green tea, ginger and cabbage also showed the antioxidant effect.
