  • Cultural practices of Asparagus cochinchinensis in highland area were performed for a potential medicinal crop. These studies were examined to propagation methods, planting densities, nitrogen treatments, and cropping years. The results are summarized as follows. The adequate number of buds per tuberous root was 4 for vegetative propagation because the number of tuberous root harvested was 16.8 and the yield was also the highest, exhibiting 1,060 kg/10a. The suitable planting time for vegetative propagation was later than early April. If the earlier tuberous roots were planted, the less they emerged. The highest emergence rate was obtained from the planting density of $30{\times}20cm$ as 97.2% while the yield was highest in the $30{\times}15cm$ density, exhibiting 1,883 kg/10a with emergence rate at 94.9. It seemed that the higher planting density promoted plant height growth and yield in Asparagus cochinchinensis. The highest fresh weight was recorded at 6 kg/10a of nitrogen fertilizer into the sandy loam soil compared to the level of 0, 3, 9 kg/10a. The yield was increased with cropping years. However, the proper harvesting time was the second year of cultivation because the rate of weight increase was maximized in the 2-year-old tuberous root. The yield in the third year was decreased as compared to that of the second year.

  • This study was carried out to examine used as fertilizer on growth and yield of Gastache rugosa. The medicinal herbs('Yeonryeonggobondan') remnant which have prescriptions of high frequency by Korean was analyzed. The medicinal herbs remnant have high content of nitrogen, phosphoric acid, potassium and organic. The growth of Agastache rugosa by application of medicinal herbs remnants were more effective than that of control. As the amount of fertilizers were increased, plant height, stem diameter, number of leaves and number of branches were increased. The growth was the highest in the treatment of 30~50 g/pot. Weight of whole plant of Agastache rugosa has a tendency to be heavy in application of medicinal herbs remnant than that of control.

  • In this study, we investigated in vitro anti-obesity activity of Parthenocissus tricuspidata (Siebold & Zucc.) Planch stem (PTS) in mouse adipocytes 3T3-L1 cells. PTS inhibited lipid accumulation and reduced the expression level of the proteins such as C/EBPα, PPARγ and FABP4 associated with adipogenesis in 3T3-L1 cells. In addition, PTS increased lipolysis-related protein expression such as p-AMPK, ATGL and p-HSL, and reduced perilipin-1 in 3T3-L1 cells. Taken together, PTS may have anti-obesity activity through inhibiting adipogenesis and inducing lipid lipolysis in adipocytes. Based on these results, PTS is expected to be used as a potential functional agent for anti-obesity.

  • In this study, we measured the inhibitory activity of Pinus densiflora leaf (PDL) against excessive lipid accumulation in mouse preadipocyte, 3T3-L1 cells to investigate whether PDL exerts anti-obesity activity. Lipid accumulation and the protein level were measured using Oil red O staining assay and Western blot analysis, respectively. We observed that PDL inhibited excessive lipid accumulation and decreased the expression of CEBPα, PPARγ and perilipin-1 related to lipid accumulation in 3T3-L1 cells. Therefore, considering these results, PDL can be used as a potential agent for anti-obesity.

  • Objective : For the purpose of developing Korean Primulaceae plants, the literature published so far have been thoroughly investigated to prepare this article. Methods : Books and research papers about Herbology which published at Korea and other countries were examined. Results : The results of this study were as follows: 1. A total of 8 genera and 30 species of Primulaceae was found in the Korea, among which 4 genera and 9 species (approximately 30%) were medicinal plants. 2. Among Korean Primulaceae plants, Lysimachia was the most with 11 species. 3. Among medicinal plants, Lysimachia was the most with 5 species, followed by 1 species of Anagallis, 1 species of Primula, and 2 species of Androsace. 4. The domestic distribution of medicinal plants was 4 species in the north part, 7 species in the central part, 7 species in the south part, and 7 species in Jeju island. 5. Among the medicinal parts, the whole body was used the most with 9 species. Among the property flatness property was the most whith 10 species.

  • Irradiated and non-irradiated Korean medicinal herbs were extracted by water and 70% ethanol. Antimicrobial activity of these extracts were invesigated against selected food hygiene microoganisms. The ethanol extracts of the non-irradiated Agrimonia pilosa ledebour japonica Nakai, Curcuma longa Linne and Angelica gigas Nakai were completely inhibited on four species of bacteria, such as Vibrio parahaemolyticus, Clostridium perfringenes, Bacillus subtilis and Staphylococcus aureus. Also, above four strains did not have antibacterial activity in the water-ethanol mixtures. Futhermore, the ehtanol extracts of the non-irradiated Agimonia pilosa ledebour Japonica Nakai, Curcuma Iedoaria Roscoe, Curcuma longa Linne and Scutellaria baikalensis George were shown inhibitory effects against Aspergillus flavus and Pen icillium islandicum. And the water extract of Scutellaria baikalensis George was the same effect to these molds. Essentially the same results were observed when samples irradiated at a dose of 10 kGy.

  • The inhibitory activity of ent-norsecurinine alkaloid was evaluated against spore germination of some plant pathogenic fungi(Curvularia maculans, Curvularia species, C. palliscens, Colletotrichum gloeosporioides, Colletotrichum species, Afternaria solani, A. brassicae, Fusarium udum, Helminthosporium echinoclova and H. penniseti). It inhibited spore germination of all the test fungi. C. maculans, C. species, and C. palliscens were the most sensitive as complete inhibition of spore germination was observed at 1000 ppm. A. solani was not inhibited by this chemical.

  • Korean medicinal herb extracts(KMHE) were applied to the preservation of greenhouse produce in order to prove their effectiveness. KMHE showed remarkable antimicrobial effects against Bacillus cereus, Peudomonas syringae, and Corynebacterium xerosis causing the postharvest decay of greenhouse produce. Among KMHE the extracts of Rheum palmatum L. and Coptis chinensis Franch most obviously inhibited the growth of microorganims causing the Postharvest decay of greenhouse produce, which destroyed to undetectable levels when treated with more than 500ppm of KMHE. The activities of KMHE were stable in the wide spectrum of pH and temperature. Direct visualization of microbial cells by using both transmission electron microscope and scanning electron microscope showed microbial cell membrane the function of which was destroyed by treating with the dilute solutions of KMHE. This change of cellular membrane permeability could be identified in the experiment that O-nitrophenyl-$\beta$-D-galactopyranoside(ONPG), the artificial substrate of $\beta$-galactosidase, was hydrolyzed in the presence of KMHE, indicating that the membrane was perturbed by KMHE.

  • N-(2-Amamantyl)-N-(5-arylhydrazono-6-methyl-4-oxopyrimidin-2-yl) guanidines (IIIa, b), 2-(2-admantyl-amino)-4-amino-s-triazine (IVa) and its 6-chloromethyl derivative (IVb) were prepared by cylization of 1-(2-admantyl) biguanide HCl (I) with ethyl 2-arylhydrazono-3-oxobutyrates (II), ethyl formate and ethyl chloroacetate, respectively. Where 1-(2-admantyl)-3-(4, 5-dioxo-2-imidazolidinylidene)guanidine (V) was used as intermediate for the synthesis of amides (VIIa, b), hydrazide (VIII) and azomethine derivatives (IX, b) of alkyl 2-(2-admantyl-amino)-4-amino-2-triazine-6-carboxylates (VI a, b). The antimicrobial testing of the prepared compounds proved that compound 1Xb was the most active. It showed a marked bacteriostatic effect against Staphylococcus aureus and Bacillus subtilis.

  • This study was conducted investigate the effect of medicinal plant extracts on physiological and sensory characteristics. The medicinal plant extracts were added to chocolate at a weight percentage of 0, 3 and 6%. Color values(L-value, redness, and yellowness), total flavonoids, DPPH radical scavenging activity, and sensory characteristics made with varying various medicinal plants concentrations of the additives were measured. In sensory evaluation, significant differences(p<0.05 and p<0.01) were shown in taste, texture, and overall acceptability depending on the addition of plant extracts, but there were no significant differences in chocolate aroma and bitterness properties.
