  • A phytosociological study on the community structure was carried out in the evergreen broad-leaved forests around Baegunbong area in Wando from June to August, 2000. A total of 31 plots, the size of which was $10m{\times}30m$, were set up in the study area. Cluster analysis for the total 54 tree species appearing in the 31 plots, showed that forest community cloud be classified into 5 groups, such as : Quercus acuta community, Quercus acuta-Camellia japonica community, Quercus acuta-Deciduous broad-leaved tree species community, Quercus acuta-Evergreen Deciduous broad-leaved tree species community, Quereus acuta-Carpinus tschonoskii community. The species of high appearance frequency ratio in 31 plots were Quercus acuta, Camellia japonica, Styrax japonica, Eurya japonica, Ligustrum japonicum, Cinnamomum japonicum, Sapium japonicum and Acer psuedo-sieboldianum. Dominant tree species were covered with Quercus acuta, Styrax japonica, Prunus sargentii, Carpinus laxiflora and Quercus serrata, and Quercus acuta, Camellia japonica, Eurya japonica, Ligustrum japonicum, Cinnamomum japonicum and Sapium japonicum at sub-canopy. The forest vegetation in the surveyed area except the summit of Baegunbong will be proceeding with Quercus acuta community. The species diversity of Quercus acuta community, Quercus acuta-Camellia japonica community, Quercus acuta-Deciduous broad-leaved tree species community, Quercus acuta-Evergreen Deciduous broad-leaved tree species community, and Quercus acuta-Carpinus tschonoskii community were 0.687, 0.866, 0.933, 0.966, and 1.018, respectively.

  • The prevalence of obesity is increasing worldwide, and since obesity is associated with dietary factors and sedentary lifestyles, it is a disease that is readily developing in the modern population. Because obesity is accompanied by serious complications such as diabetes and cardiovascular disease, prevention and treatment are important. Currently, drugs such as liraglutide and phentermine are used to treat obesity by suppressing appetite and inducing gastrointestinal motility delay. However, various side effects may occur, including thyroid cancer, cardiovascular problems, and central nervous system disorders. Therefore, to explore an obesity treatment method with relatively few side effects, a method known as "fat browning" was introduced to change white adipose tissue into brown adipose tissue to increase energy consumption. Ongoing studies are attempting to find effective natural substances to safely induce browning. Many natural substances have been identified. The induction of browning by treatment with natural substances generally involves three mechanisms: positive control of browning-inducing factors, inhibition of differentiation into white adipose tissue, and the activation of mechanisms related to browning. In this study, we describe plant extracts with known browning-inducing effects, such as strawberry, black raspberry, cinnamomum cassia, and Ecklonia stolonifera extracts. We also summarize the underlying mechanisms of action identified thus far, including the signaling pathway mediated by these extracts to induce browning. Furthermore, the effects of brown adipose tissue generated through browning on heart disease as an endocrine organ disruptor are discussed.

  • This study determined the effects of addition of medicinal herb extracts (Zanthoxylum piperitum extract(TZ), Acanthopanax sessiliflorus(TA), Panax ginseng(TP), Cinnamomum lureitri Nees(TC), Angelica gigantis radix(TAG) and Crataegii fructus extract (TCF) to teriyaki sauce with regard to taste and health benefit. After adding the medicinal herb extracts to teriyaki sauce, moisture content was found to be inversely proportional to the viscosity. The sauce with Panax ginseng extract(TP) had lowest sweetness, but highest salinity. The results showed that the sauce with Korean herb extracts had lower salinity content. In terms of colour value, the sauce with Crataegii fructus extract(TCF) had much higher lightness, redness, and yellowness than sauce prepared with other herb extracts. It had the strongest acidic taste and lowest pH. Sensory evaluation test revealed that the sauce with Anthoxylum piperitum extract(TZ) was the most preferred sauce among all the sauces tested. The degree of brown color of teriyaki sauces was correlated positively with taste preference(r=.570, p<0.01) and overall preference(r=.505, p<0.01).

  • Environmental microbes like Bordetella petrii has been established as a causative agent for various infectious diseases in human. Again, development of drug resistance in B. petrii challenged to combat against the infection. Identification of potential drug target and proposing a novel lead compound against the pathogen has a great aid and value. In this study, bioinformatics tools and technology have been applied to suggest a potential drug target by screening the proteome information of B. petrii DSM 12804 (accession No. PRJNA28135) from genome database of National Centre for Biotechnology information. In this regards, the inhibitory effect of nine natural compounds like ajoene (Allium sativum), allicin (A. sativum), cinnamaldehyde (Cinnamomum cassia), curcumin (Curcuma longa), gallotannin (active component of green tea and red wine), isoorientin (Anthopterus wardii), isovitexin (A. wardii), neral (Melissa officinalis), and vitexin (A. wardii) have been acknowledged with anti-bacterial properties and hence tested against identified drug target of B. petrii by implicating computational approach. The in silico studies revealed the hypothesis that lpxD could be a potential drug target and with recommendation of a strong inhibitory effect of selected natural compounds against infection caused due to B. petrii, would be further validated through in vitro experiments.

  • To explain the theory of KIMI which is the theory of therapeutics in oriental medicine, monoamine oxidase(MAO) activities were measured in the brain and liver of mice which were orally administered oriental medicinal herbs which were classified into cold and hot drugs. Rheum palmatum, Anemarrhena asphodeloides, Gardenia jasminoides, Scutellaria baicalensis and Coptis japonica were considered as the cold drugs and Zingiber officinale, Aconitum carmichaeli, Asiasarum sieboldi, Evodia officinalis and Cinnamomum cassia were included in the hot drugs. The effects of cold and hot drugs on in vitro enzyme activities were measured and compared with the in vivo effects. Serotonin is important neurotransmetter involved in the control of body temperature. The MAO plays a central role in the metabolism of many neurotransmetter monoamines including serotonin. MAO is a flavoprotein found exclusively in the mitochondrial outer membrane, occuring in the MAO-A and MAO-B subtypes. MAO-A deaminates serotonin and noradrenaline, whereas MAO-B prefers phenylethylamine and benzylamine as substrates. Coptis japonica and Aconitum carmichaeli elevated the in vivo MAO activities and especialy, in vivo MAO-B activities were significantly increased. In vitro MAO-A activities were increased by hot drugs, whereas the in vitro MAO-B activities were inhibited. Cold drugs inhibited both enzyme activities in vitro.

  • The total phenolic contents and antioxidative activities of the ethanol and methanol extracts from 9 Korean medicinal herbs were tested for the application of skin care products such as soaf and lotion. For the evaluation of antioxidative activity of the extract the method of electron donating ability with resolution reagent DPPH(1 ,1-diphenyl-2-picryl hydrazyl) and TBARS (Thiobarbituric acid reactive substances) value were used in comparison with α-tocopherol and BHA. As the results, the total phenolic contents of the extracts calculated as chlorogenic acid were ranged from 0.063-0.124 mg/ml. All the medicinal plant extracts showed some appreciable antioxidative effects. Among them, Zanthoxylum piperitum, Cinnamomum cassia and Caesalpinia sappan were shown to have relatively high antioxidative effects comparable with BHA and α-tocopherol..
