  • 82 species of Korean medicinal plants were measured to their SOD (superoxide dismutase) activity, total phenol and individual phenol compounds. The SOD activity of medicinal plants was varied from 3.67% to 48.3%, and especially, 4 species including Polygala tenuifolia Willd. showed activity over 40% higher than other species. The 16 individual phenol compounds concentrations have a severe variation in medicinal plants. Codonopsis lanceolata is the highest concentration $(12,176\;{\mu}g/g)$, and 10 species including Glycyrrhiza uralensis Fisch were showed to concentrations more than $1,000\;{\mu}g/g$. And also, salicylic acid was generally found in many plants, but trans-cinnamic acid, naringenin and kampferol was little found in plants. The total phenol by Folin-Dennis methods showed a respectively variation $(3{\sim}249.731\;{\mu}g/g)$ in 82 medicinal plants, and 7 species including Astragalus membranaceus showed low total phenol concentrations less than $10\;{\mu}g/g$. In conclusion, we expect that selecting medicinal plants with high biological activity might develop to chemicals related to antioxidants, as well as these become most popular substance at many industrial materials, and suggest to more researchs in future.

  • In an effort to characterize the physicochemical properties and microbial risks associated with the soy sauce jangachi (Korean traditional pickle), 15 different home-made products, which were prepared from medicinal plants and wild edible vegetables, from head-families of Andong, Kyungsangbuk-do Province in Korea, and 6 different commercial products sold at supermarket, were investigated. The average pH of the mature soaking solutions and plants soaked in the 21 jangachi were $3.99{\pm}0.38$ and $3.51{\pm}0.41$, and the average acidity of the mature soaking solutions and soaked plants were $1.59{\pm}0.54$ and $1.65{\pm}0.76$, respectively. The average brix of the mature soaking solutions and plants soaked were $27.67{\pm}8.38$ and $25.61{\pm}6.60$, respectively. In salinity, which is a major factor in jangachi industry production, the average salinity of the mature soaking solutions and soaked plants were $7.55{\pm}3.26$ and $5.75{\pm}2.23$, respectively. In particular, the hot-peppers, eusuri, du-rup, kaet-ip, kuji-ppong, myeng-i and sancho jangachi were amongst the home-made products, and the salinity was above 8.8%, which was 2 folds-higher than that of the commercial sterilized products, and 1/3-lower than commercial non-sterilized products. The color difference and turbidity of jangachi were dependent on the plant parts used. In microbial risk assessment, the microorganisms related with food-borne disease, such as Escherichia coli, Salmonella sp, and Shigella sp., were not detected. After some time, total cell count analysis revealed that the commercial products sold at supermarkets were more vulnerable than the home-made products.

  • This study was performed to evaluate the possible production of a functional beverage derived from abalone and with several plants (AP). Five types of AP composites were prepared having different medicinal plant compositions (AP- I : abalone, garlic, jujube, Chinese matrimony fruit, dried orange peel, licorice root, zinger, honey; AP- II: abalone, garlic, black bean, Chinese matrimony fruit, cornus fruit, licorice root, zinger, honey; AP-III : abalone, jujube, arrow root, milk vetch, dried orange peel, licorice root, zinger, honey; AP-N: abalone, black bean, arrow root, milk vetch, cornus fruit, liquorice root, zinger, honey; AP-V : abalone, garlic, Chinese matrimony fruit, milk vetch, licorice root, zinger, honey). In vitro analysis were performed to examine the antioxidant contents and alcohol dehydrogenase activities of the composites. AP- II had the highest total phenol contents ($28.55{\pm}1.56\;mg/l00\;g$), and AP- V the highest level of flavonoids ($47.61{\pm}1.58\;mg/l00\;g$). At $78.89{\pm}0.16%$, AP- V displayed the strongest electron donating ability followed by AP-II($57.99{\pm}0.21%$) and API ($37.66{\pm}0.20%$). Reducing power was also significantly higher in AP- V. The Hydroxyl radical scavenging and SOD-like activities of all composites were less than 15% and 20%, respectively. At 12.5% alcohol concentration, ADH activity ranged from $114.47{\pm}2.18{\sim}121.39{\pm}4.36%$ and ALDH activity ranged from $100.04{\pm}2.90{\sim}129.54{\pm}4.80%$; AP- I , AP- II, and AP- Vin 12.5% of alcoholic concentration. The composites of AP- I , AP- II, and AP- V, all containing garlic and Chinese matrimony fruit, were significantly stronger than AP-III and AP-N. Finally, also at 12.5% alcoholic concentration, the ALDH activity of AP- V was higher than its ADH activity.

  • The purpose of this study was to measure total phenolic compounds as a measure of antioxidant activity as well as ${\alpha}$-amylase inhibitory and ${\alpha}$-glucosidase inhibitory activities as a measure of anti-diabetic efficacy in methanol extracts from 23 kinds of medicinal plants. Extracts of three medicinal plant species showing high total polyphenol contents were selected (Euonymus alatus stem, Taxus cuspidata fruit, and Eucommia ulmoides leaf). Extracts of six medicinal plant species showing over 60% DPPH radical scavenging activity were also selected [Eucommia ulmoides barks (80.10%), Lycium chinense roots (64.25%), Euonymus alatus stem (73.59%), Lespedeza cuneata (78.20%), Taxus cuspidata fruits (70.52%), and Tilia taquetii leaf and stem (67.81%)]. Regarding ${\alpha}$-glucosidase and ${\alpha}$-amylase inhibitory activities acarbose showing approximately 80% inhibitory activity was selected as a control group, and six species (Eucommia ulmoides heartwood, Eucommia ulmoides bark, Euonymus alatus stem, Dioscorea batatas, Coix lachryma-jobi, and Phaseolus radiatus) showed greater than 80% ${\alpha}$-glucosidase inhibitory activity. Extracts of nine medicinal plant. species showing over 80% ${\alpha}$-amylase inhibitory activity (Pueraria thunbergiana root, Eucommia ulmoides bark, Eucommia ulmoides leaf, Lycium chinense fruits, Euonymus alatus leaf and stem, Euonymus alatus stem, Sasa borealis whole, Dioscorea batatas leaf and stem, and Tilia taquetii leaf and stem). Based on these results, medicinal plants showing high antioxidant and antidiabetic activities can be used as fundamental products in developing new medicines, as well as functional foods to prevent adult disease.

  • In this study, cysteine compounds found in genus Allium plants, including N-acetyl cysteine(NAC), S-allyl cysteine(SAC), S-ethyl cysteine(SEC), and S-methyl cysteine(SMC), were examined for effects on blood glucose, glucose tolerance, and plasma lipid concentrations in streptozotocin(STZ)-induced diabetic mice. In the mice, the ingestion of these cysteine compounds did not affect blood glucose levels significantly. However, their ingestion did improve the diabetic symptoms of polydipsia, polyphagia, polyuria, and weight loss. Glucose tolerance was also found to be improved in the STZ diabetic animals by feeding the cysteine compounds. Treatment of the compounds also caused a slight decrease in plasma concentrations of total cholesterol along with increases in HDL-cholesterol and slight decreases in LDL-cholesterol, resulting in a significant decrease in the atherogenic index of plasma in the diabetic animals. They also showed reductions of liver triglyceride content to relieve diabetic fatty liver syndrome. In summary, the cysteine compounds such as NAC, SAC, SEC, and SMC, found in genus Allium plants, had certain beneficial effects on blood glucose metabolism along with preventing abnormalities in lipid metabolism, a complication of diabetes, by improving the atherogenic index of plasma and fatty liver in STZ-induced diabetic mice.

  • This study was aimed at investigating hepatic toxicity and immunomodulating effects of defatted methanol extracts of two kinds of medicinal plants, Rubus coreanus Miq. and Atractylodes japonica Koidz. in mice. Defatted methanol extracts of fruits of Rubus coreanus Miq. and rhizome of Atractylodes japonica Koidz. were added at the level of 0.5% or 5%(w/w) to cholesterol-supplemented AIN-76 diet. Each diet was fed to 8 ICR male mice for 30 days. Weight gain and food efficiency ratio of the mice fed 5.0% extract of Rubus coreanus Miq. were significantly lower than those of the mice fed 0.5% extract Relative liver weight and activity of plasma alanine aminotransfernse were significantly increased only in the mice fed 5% extract of Atractylodes japonica Koidz. compared with the others. Splenocyte proliferation was not significantly different between the groups fed 0.5% or 5.0% extract of Rubus coreanus Miq. However, splenocyte proliferation was significantly decreased in the mice fed 5.0% extract of Atractylodes japonica Koidz. compared with that in the mice fed 0.5% Production of interleukin-2 by splenocytes from the mice fed 0.5% extract of Atractylodes japonica Miq. was significantly higher than the control value and it became lower with 5.0% dietary level. Secretion of $interferon-\gamma$ was not significantly different among groups. In conclusion, the defatted methanol extract of Atractylodes japonica Koidz. was likely to exert immunomodulating effect at the level of 0.5% but it may exert adverse effects on immune and liver functions at the level of 5.0%.
