  • KJHST (Kejihongsarntang) is a modified oriental prescription that consists of five herbs such as Ginseng Radix rubra Koreana, Atractylodis Rhizoma, Zingiberis Rhiaoma, Cinnamomi Ramulus and Glycyrrhizae Radix. For the evaluation of antioxidant and staminal activities of KJHST (Kejihongsarntang), the study was done in comparison of Ginseng Radix rubra (GR). For the antioxidant study, KJHST inhibited hemolysis of erythrocyte and decolored the DPPH(2,2-diphenyl-1-picrylhydrazyl) free radical in a dose depenrlent manner more effectively than GR alone in vitro. KJHST and GR significantly suppressed the time course (1 hr∼6 hr)-level of MDA (malondialdehyde) following AAPH (2,2'-azo-bis-(2-amidino-propane) dihydrochloride) treatment in vivo as compared with control data with no statistical difference. From the evaluation of stamina by swimming test GR and KJHST significantly increased the swimming time in a time and dose dependent manner as compared with control data, while GR was more effective than KJHST in 2 weeks after treatment, though KJHST was more effective than GR at low dose (25 m/kg) 4 weeks after treatment. From the results it can be concluded GR and KJHST had antioxidant and staminal activities.

  • We quantitatively analyzed eight varieties of 6-year-old red ginseng, including four local landraces from the Inje, Geumsan, Jinan, and Punggi regions and four new varieties, Chunpoong, Yunpoong, Guempoong, and K-1, for 10 ginsenosides, acidic polysaccharide, crude polyacetylene, and total polyphenol content to find out which varieties are most suitable for producing red ginseng. Most of the new varieties contained more ginsenosides than the local landraces. While the acidic polysaccharide content of Geumsan red ginseng was lower than that of the others, its crude polyacetylene content was the highest, with a mean of 33.99%. The Inje, Geumsan, and Jinan red ginseng had a significantly higher total polyphenol content than the others.

  • Plants have evolved to adapt to abiotic stresses, such as salt, cold, and drought stress. In this study, we conducted an in-depth analysis of drought resistance mechanisms by constructing a gene co-expression network in Chinese cabbage (Brassica rapa ssp. pekinensis L.). This drought stress co-expression network has 1,560 nodes, 4,731 edges, and 79 connected components. Based on genes that showed significant co-expression in the network, drought tolerance was associated with the induction of reactive oxygen species removal by raffinose family oligosaccharides and inositol metabolism. This network could be a useful tool for predicting the functions of genes involved in drought stress resistance in Chinese cabbage.
