This study was conducted to maintain the productivity of forest production and byproducts production of natural forest. Distribution of wild edible herb species and correlations between wild edible herb species and forest-type, and site factors were surveyed on national forest in Changjeon-ni, Pyungchang-gun, Kang-won-do. Ligularia fischeri was distributed mainly on cutting sites or meadow or Quercus mongolica forest, Pimpinella brachycarpa did on broadleaved mixed forest, and Synurus deltoides did cutting sites or meadow. On conifer plantations major wild edible herb species were not distributed. Pimpinella brachycarpa and Ligularia fischera were distributed mainly on the site of wet soil-moisture condition, Codonopsis lanceolata, Saussurea grandifolia and Synurus deltoides were distributed randomly. The distribution of Ligularia fischeri and Pimpinella brachycarpa were significantly different between slope directions, but those of Codonopsis lanceolata, Saussurea grandifolia and Synurus deltoides were not significant. Ligularia fischeri and Pimpinella brachycarpa were distributed more frequently in north directed slope than the other. Highly positive correlations were proved Ligularia fischeri and Pimpinella brachycarpa, Aconitum jaluense and Veratrum patulum; Pimpinella brachycarpa and Smilacina japonica, Aconitum jaluense and Veratrum patulum.

Objectives : The aim of the research is to study the edible parts and cooking methods for the Korean medicinal plants using documents of Japanese occupation era. Through this study, we expect that it will be used as a basis data on further Korean traditional edible herb. Methods : The research analyze the usage of 74 species of medicinal plants that are listed in the 『Wild Food Plants of Chosen(Korea)』 along with analyzing 8 extra documents about famine relief plants and cooking method written during Japanese occupation. Results : The result shows that the sprouts and buds are the most popular for the edible purposes but they are never used for medical reason. Roots and fruits take the highest percentage when it comes to medical purposes. Types of medicinal plants that were used a lot of cooking methods were side dishes such as 'Namul, Saengchae, Jangajji'. Conclusions : Using medicinal plants for edible and medical purposes were traditionally familiar with Korean culture but the changes provoked by industrialization forbid the knowledge to pass through. However, recently, the trend of having a healthy life interests people to backtrack this traditional way of using medicinal plants with new purposes. To inherit traditional knowledge and for the future development of Korean traditional ingredients, further research should be conducted.

Aster yomena (Kitam.) Honda is an edible vegetable and perennial herb belonging to the Asteraceae family, and has been used for a long time for the prevention and treatment of various diseases. Although leaf extracts of A. yomena are known to have antioxidant and anti-inflammatory effects, accurate efficacy assessments are still inadequate. In this study, we investigated whether the antioxidant efficacy of ethanol extract of A. yomena leaf (EEAY) is correlated with the anti-inflammatory effect in RAW 264.7 macrophages. The results showed that EEAY significantly inhibited the hydrogen peroxide ($H_2O_2$)-induced growth inhibition in RAW 264.7 cells, which was associated with increased expression of nuclear factor erythroid 2-related factor-2 (Nrf2) and heme oxygenase-1 (HO-1). EEAY pretreatment also effectively prevented $H_2O_2$-induced reactive oxygen species generation and apoptosis through inhibition of caspase-3 activation and poly (ADP-ribose) polymerase degradation. Additionally, EEAY significantly increased the expression and production of interleukin-10, a representative anti-inflammatory cytokine, which was associated with increased expression of toll-like receptor 4 and myeloid differentiation factor 88 at transcriptional and translational levels. Furthermore, the increased production of nitric oxide (NO) by lipopolysaccharide was markedly abolished under the condition of EEAY pretreatment, and the inhibitory effect of NO production by EEAY was further increased by hemin, an HO-1 inducer. Overall, our results suggest that EEAY is able to activate the Nrf2/HO-1 signaling pathway to protect RAW 264.7 macrophages from oxidative and inflammatory stress.
