  • This study was performed to investigate the effect of dietary medicinal herb extract mix (MHEM, mulberry leaf : Japanese honeysuckle : goldthread=48.5:48.5:3.0) on antioxidative activity of chicken thigh meat. The dietary treatments consisted of a corn-soybean meal basal diet (control), basal diet with 0.3% and 1% MHEM. At the end of the feeding trial, thigh meat samples were collected and stored in a refrigerator at $4^{\circ}C$ to be analyzed on day 0, 3, 7 and 14. The MHEM did not affect proximate composition of the thigh meat. Total phenol contents of the thigh meats in treatment groups were higher than that of the control (p<0.05). 1,1-Diphenyl-2-picrylhydrazyl radical scavenging activity were higher in dietary treatment group. 2-Thiobarbituric acid reactive substances values of the treatment group were lower than that of control at day 7 and 14 and the added level also affected the inhibition of lipid oxidation of thigh meat. In sensory test, panelists preferred treatment group at day 7 and 14. Therefore, results indicate that dietary MHEM added to chicken may retard the oxidative deterioration of chicken thigh meat during cold storage.

  • In the present study, we investigated antimicrobial activity of the medicinal plants against various strains of methicillin-resistant Staphylococcus aureus (MRSA) and Staphylococcus aureus (S. aureus). Among the tested, the plants extracts of Asiasarum heterotropoides var. mandshuricum, Coptidis rhizoma, Reynoutria elliptica Migo., Solidago virga-aurea var. gigantea Miq.seed exhibited significant antimicrobial activities against MRSA KCCM 11812, 40510 and S. aureus ATCC 25923. The methanol extract of Asiasarum heterotropoides var. mandshuricum showed strong antimicrobial activity against MRSA KCCM 11812, 40510 and S. aureus ATCC 25923 at the 5 mg/disc. A synergistic effect was found in combined extracts of Asiasarum heterotropoides var. mandshuricum and Coptidis rhizoma as compared to each extracts alone. The result suggests that medicinal plant extracts can be used as an effective natural antimicrobial agent in food.

  • This study is attempted to prepare criteria to determine target species for conservation, through analyzing vascular flora and medicinal resources plants of Mt. Daedeok and Geumdae-bong in Gangwon Province, Korea. Flora Surveys were conducted 14 times from April, 2017 to October, 2019. Total 428 taxa with 83 families, 245 genera, 356 species, 5 subspecies, 46 varieties and 21 forms were distributed in Mt. Daedeok and Geumdae-bong. Korean endemic species were composed of 19 species. Total 36 taxa of Korean rare plants species were identified including 5 taxa in the degree of CR, 2 taxa in the degree of EN, 12 taxa in the degree of VU, 14 taxa in the degree of LC and 3 taxa in the degree of DD. The naturalized plants were 5 families, 10 genera, 10 species, totaling 10 taxa and medicinal resources plants were 239 taxa with 73 families, 185 genera, 239 species, 30 varieties 4 forms, 4 subspecies. The Urbanization Index (UI) was 2.5% and the Naturalized Index (NI) was 1.9%.

  • This study was performed to certify the inhibitory effect of aqueous extracts from sixty-seven medicinal plants on the activity of xanthine oxidase in vitro. Among the sixty-seven medicinal plants, Scutellaria baicalensis Georgi, Citrus aurantium L., Polygonum multiflorum Thunb., Pueraria thunbergiana (Sieb. et Zucc.) Benth., Citrus unshiu Marcor., Rubus coreanus Miquel, Camellia sinensis L., and Poncirus trifoliata Raf. were regarded as effective anti-gout sources. The active substances of P. multiflorum root extract were very stable at pH 2.0 and high temperatures. Xanthine oxidase activity was proportionally inhibited when concentrations of P. multiflorum extract increased. The aqueous extract from P. multiflorum root at a concentration of 2.0 mg/0.1 mL inhibited xanthine oxidase by 73.8%.

  • 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.
