Objectives : To determine the discriminative criteria for Atractylodes rhizomes, the experiment of externalinternal characteristics and physicochemical pattern analysis were performed. Methods : External characteristics was observed using stereoscope. The sectioned materials which were covered with parffin were stained by Ju's method. Physicochemical patterns were analyzed using HPLC/DAD. Results : 1. External shape of original plant : Atractylodes maaocephala and A. japonica had relatively long petioles and 3-5 parted leaves. A. macrocephala had big purple flowers whereas A. japonica had relatively small white flowers and pinnate bracts. A. lancea had sessile leaves and white flowers, and the end parts of degenerated stamens were bent. 2. External shape of herbal medicine: A. macrocephala which was fist-shaped rhizome had pa-pillate processes and the cross section was light gray and sulcate. A. japonica and A. lancea were connected-beady or tubercular rhizomes, and the cross sections were both yellow-colored white. However, the cross section of A. japonica was fibrous, the width of cortex was narro-wer than that of stele, and radial shape in cortex was rare, whereas the width of cortex in A. lancea was similar to that of stele in size, and radial shape in cortex was obvious. 3. Internal shape of herbal medicine: A. macrocephala and A. lancea did not have lignified fascicles in cortex. However, the vascular bundles and vessels of A. macrocephala were wedge shaped and radial arrangement, and vascular bundles were densely populated in stele whereas those of A. lancea were repeatedly arranged and thinly extended to cortex. A. japonica had lignified fascicles in cortex and the width of vascular bundles was conspicuously thick with narrow intervals. 4. Physicochemical pattern analysis : A. macrocephala and A. lancea contained atractylenolide I and atractylenolide Ill whereas A. japonica contained atractylenolide I, atractylenolide Ill. diacetyl-atractylodiol, compound-4, compound-5. The three species of Atractylodes rhizomes showed different chromatogram patterns. Conclusions : The results could be used as discriminative criteria for Atractylodes rhizomes and as fundamental materials to researches of further pattern analysis and biological reaction.

Objective: The present study investigated whether protodioscin (PD), a steroidal saponin mainly found in rhizome of Dioscorea species, alleviates oxidative stress-induced damage of porcine oocytes during in vitro maturation. Methods: Oocytes were treated with different concentrations of PD (0, 1, 10, 100, and 200 µM) in the presence of 200 µM H2O2 during in vitro maturation. Following maturation, spindle morphology and mitogen-activated protein kinase activity was assessed along with reactive oxygen species level, GSH activity, and mRNA expression of endogenous antioxidant genes at the MII stage. On the day 7 after parthenogenetic activation, blastocyst formation rate was calculated and the quality of embryo and mRNA expression of development-related genes was evaluated. Results: Developmental competence was significantly poorer in the 0 µM PD-treated (control) group than in the non-treated (normal) and 10 µM PD-treated (10PD) groups. Although the reactive oxygen species level did not significantly differ between these three groups, the glutathione level and mRNA expression of antioxidant genes (superoxide dismutase 1 [SOD1], SOD2, nuclear factor erythroid 2-related factor 2 [Nrf2], and hemo oxygenase-1 [HO-1]) were significantly higher in the normal and 10PD groups than in the control group. In addition, the percentage of oocytes with defective spindle and abnormal chromosomal alignment was significantly lower and the ratio of phosphorylated p44/42 to total p44/42 was significantly higher in the normal and 10PD groups than in the control group. The total cell number per blastocyst was significantly higher in the 10PD group than in the control group. The percentage of apoptotic cells in blastocysts was highest in the control group; however, the difference was not significant. mRNA expression of development-related genes (POU domain, class 5, transcription factor 1 [POU5F1], caudal type homeobox 2 [CDX2], Nanog homeobox [NANOG]) was consistently increased by addition of PD. Conclusion: The PD effectively improves the developmental competence and quality of blastocysts by protecting porcine oocytes against oxidative stress.
The purpose of this study was to identify the propagation characteristics of Diabelia spathulata (Siebold & Zucc.) Landrein through seeding and cutting methods. The seed germination rate was meager (0.22~3.56%). In hardwood cutting, the highest rooting rate was 36.1% in sand + perlite (2:1) and 37.8% in 1000 PPM of IBA pre-treatment. Softwood cutting showed the highest rooting rate when the cutting diameter was 3 to 5 mm and the cutting length was 7 to 8 cm. In particular, the highest rooting rate of 80% was observed in the sand among the 8 cultivation media treatments. In the case of root cuttings, the rooting rate was 83.3~96.7% in all cultivation media. The highest rooting rate was observed when the diameter of the cutting was 7 to 8 mm, and the length of the cutting was about 10 to 11 cm. Among cutting methods, root cutting showed the highest rooting rate. Division showed a 100% rooting rate regardless of size or growth status. For Diabelia spathulata (Siebold & Zucc.) Landrein, propagation by cuttings was more efficient than seeding. However, Further research on the morphophysiological dormancy and dormancy break of seeds is needed for seed propagation.

Calystegia soldanella L. is a perennial herbaceous halophyte belonging to the convolvulaceae family, which mainly grows in coastal sand dunes in Korea. Shoots and rhizomes are edible, and roots called 'Hyoseon Chogeun' are known to have medicinal effects such as antipyretic, sterilization, and diuretic. In addition, physiological activities of antioxidant, anti-inflammatory, antiviral, antifungal and PTP-1B (protein tyrosine phosphate-1B) inhibition have been reported. In this study, in vitro induction cell lines of C. soldanella L. collected from the coastal sand dunes in Jeju island was redifferentiated into adventitious roots that can be used as medicinal resources. Also the biomass of mass-proliferated adventitious roots using a bioreactor were evaluated. Plants of C. soldanella L. were collected from the crevice of the seashore in the coastal area of Taeheung 2-ri, Namwon-eup, Seogwipo-si. Then, it was separated into leaves, stems, rhizomes, and roots, and surface sterilized with 70% ethyl alcohol and 2% NaOCl (sodium hypochlorite). After washing with sterilized water, each organ section was cultured in Hormone-free MS medium (Murashige & Skoog Medium). As a result, the induction response rates were evaluated at 85% and 55%, respectively, in terms of callus formation and shoot generation in the rhizome segment. In the case of the adventitious roots morphological characteristics induced by single-use treatment of auxin-based plant growth regulators IBA and NAA from redifferentiated shoots were compared. Most efficient adventitious root culture method as a rooting rate, number, length, and biomass proliferation in the bioreactor system was confirmed when treated by culturing in MS salts, Sucrose 30 g·L-1, and IBA 1mg·L-1 for 4 weeks. In this study, the medium composition and culture period were confirmed using a bioreactor system to mass-proliferate adventitious roots derived from C. soldanella L. in Jeju island. Also this adventitious root line developed a new medicinal material could increase value of the bio-industry ingredient through quantitative and qualitative screening of phyto-bioactive compounds.

Hypochaeris radicata, native to Europe and Eurasia, is a perennial plant of the Asteraceae family. In Korea, H. radicata was reported in 1992, mainly in Jeju Island, and gradually spreading to the inland. It overwinters in the form of a rosette and blooms yellow flowers from May to June. H. radicata propagates by seeds and rhizomes. The germination temperature of the seed is 15/20℃ (day/night), and the rhizome forms a new plant at a depth of 2-3cm in the soil. The roots of H. radicata secrete allelochemicals that inhibit the development of other plants. Some use it as a salad or forage substitute but to a limited extent. However, extensive research on ampicillin contained in H. radicata has been conducted, and its anticancer and anti-inflammatory effects have been recognized. There are only a few methods to manage H. radicata both culturally and physically. In orchards, soil treatments such as oxyfluorfen and diclobenil, or nonselective foliar treatments such as glufosinate-ammonium and glyphosate are used. Notably, there are no known biological control agents.
Yams (Dioscorea spp.) have been used as medicinal and edible resources worldwide. In the present study, methanol extracts were prepared from various kinds of yam, including D. batatas (Gyeongbuk No. 1 and No. 4), D. alata L. (Gyeongbuk No. 5 and No. 6), and D. bulbifera and D. nipponica, and the antioxidant, antithrombin, and antimicrobial activities of these extracts were evaluated. The water content of the various yams was 54.7~83.2% (D. batatas> D. alata L.>D. nipponica>D. bulbifera) and the methanol extracts contained 0.59-1.59% (w/v) solid matter (D. alata L.>D. batatas >D. nipponica>D. bulbifera). The mean concentrations of total polyphenols, total flavonoids, and total sugars in the different types of yam were 49.82 mg/g, 9.79 mg/g, and 173.81 mg/g, respectively. Analysis of DPPH radical-scavenging activity showed that D. alata L. Gyeongbuk No. 6 had a strong antioxidant capacity (IC50=$142.30{\mu}g/mL$), whereas the other yams showed reduced levels of activity (IC50=371-$486{\mu}g/mL$). D. alata L. Gyeongbuk No. 6 showed a strong antithrombin activity against human thrombin. Upon treatment with a D. alata methanol extract (1.5 mg/mL), thrombin time was increased 7.35-fold compared with that when methanol alone was used. In an antimicrobial activity assay, the D. nipponica extract showed moderate antibacterial activity against Bacillus subtilis, Staphylococcus aureus, Proteus vulgaris, and Salmonella typhimurium. Our results indicate that different varieties of Dioscorea spp., including D. batatas, have useful biochemical attributes, including antioxidant, antithrombin, and antibacterial activities.
This study was conducted to evaluate the antimicrobial and antioxidant effects of ripened medicinal herb extracts from wood vinegar. The wood vinegar was collected from heated oaks. The Allium sativum (AS), Atractylodes ovate (AO), Cin-namomum zeylanicum (CZ), Coptidis rhizome (CR), Houttuynia cordata (HC), Phellodendron chinense (PC) and Syzygium aromaticum (SA) extracts were collected using wood vinegar, and they were ripened under room temperature for 50 days. All ripened medicinal herb extracts were used to test the antimicrobial and antioxidant activities. For the Lactobacillus, clear zone of 6 different medicinal herb except for CR ranged from 1.28 to 1.63 mm. 3.30 and 3.48 mm of clear zone were determined when CZ and SA were applied to Salmonella and E. coli, respectively (p<0.05), and they showed the largest clear zone as compared to other herbs. The clear zones of CR for Salmonella and E. coli were 2.21 and 3.34 mm, and each clear zone of CR was smaller than that of CZ (p<0.05) but was similar to that of SA (p>0.05). The amount of polyphenol and flavonoid was the highest in SA and CR, and they were 4.28 and 0.38 mg/mL, respectively (p<0.05). The CR shown 0.38 mg/mL flavonoid, had the highest DPPH, and it was 0.41 mM. The DPPH of HZ was significantly lowered in accordance with high amount of polyphenol and flavonoid, 2.56 and 0.20 mg/mL (p<0.05). In conclusion, CZ, SA, and CR showed high antimicrobial and antioxidant potentials, and therefore, may be used as alternatives to antibiotics for poultry diets.
Objectives: The purpose of the present study is to investigate anti-depressive effects of Samul-tanggahyangbuja (SGH) on ovariectomized and chronic mild stress (CMS) induced rats. Methods: Ovariectomized rats were exposed to CMS for 4 weeks. Changes of depression behavior were tested by using sucrose intake test (SIT), elevated plus maze (EPM), forced swimming test (FST) and Morris water maze test (MWMT) in rats until being orally medicated with SGH (100 or 400 mg/kg/day). In addition, the serum levels of corticosterone (CORT), IL-4, IL-$1{\beta}$ and changes of 5-HT in the brain were measured. Results: 1. SGH 400 mg/kg treated group (SGH 400) significantly increased amount of sucrose intake compared with the control group (p<0.05). 2. SGH 100 mg/kg treated group (SGH 100) and SGH 400 significantly increased the time spent in the open arms of the EPM compared with the control group (p<0.01). SGH 400 also significantly increased the number of crossing of the open and closed arms compared with the control group (p<0.05). 3. SGH significantly shortened the immobility time in FST compared with the control group (SGH 100 p<0.05, SGH 400 p<0.01). 4. SGH significantly increased performance of acquisition trials compared with the control group (p<0.05, on day 4, 5 of SGH 100 and 400). SGH 400 also significantly increased performance of retention trials compared with the control group (p<0.05). 5. The serum levels of corticosterone and IL-4 were not significantly different among the groups. There were no changes on the serum levels of corticosterone, IL-$1{\beta}$ and IL-4 after administration with SGH. 6. SGH 400 significantly increased the level of 5-HT in the hippocampus compared with the control group (p<0.05). SGH significantly increased the levels of 5-HT in the hypothalamus compared with the control group (SGH 100 p<0.05, SGH 400 p<0.01). Conclusions: These results suggest that SGH has the anti-depressive effect on ovariectomized rat and affect 5-HT system rather than hypothalamic-pituitary-adrenal (HPA) axis and immune system.

This study is aimed to evaluate the protective effect of Gastrodiae rhizoma and steamed, dried & fermented Gastrodiae rhizoma on Lipopolysaccharide (LPS)-induced hepatic injury in the mice model. Sample was selected to GR0F0 (not processed gastrodia rhizome) and GR6F4 (fermented with Saccharomyces cerevisiae before steamed and dried 6 times) based on 1,1-diphenyl-2-picrylhydrazyl, 2,2'-azinobis-3-ethyl-benzothiazoline-6-sulfonic acid, and High-performance liquid chromatography analysis. Mice were randomly divided into 4 groups - Normal group, vehicle group (LPS treated), GR0F0 group (fed GR0F0 before LPS treated) and GR6F4 group (fed GR6F4 before LPS treated) with 6 mice in each group. GR0F0 group and GR6F4 group were fed each extract 200 mg/kg/day during 8 days. LPS 20 mg/kg injected to the experimental groups as abdominal injection. We measured aspartate aminotransferase, alanine amino-transferase in serum. GR0F0 and GR6F4 showed a significant decrease compared to the vehicle group. As a result of measuring the ROS, GR6F4 group showed a significant reduction in both the serum and liver tissues compared to the vehicle group. GR0F0 group showed a significant reduction only in the liver tissues. Activator protein-1, cyclooxygenase-2, and Inducible nitric oxide synthase were significantly decreased GR0F0 group and GR6F4 group. But tumor necrosis factor alpha only showed a significant reduction in GR6F4 group. GR0F0 and GR6F4 groups against liver damage in mice with LPS. That showed significant effects on anti-oxidant and anti-inflammatory action. The effects of GR6F4 group showed superior results compared to GR0F0 group. Therefore, Steamed, dried & fermented Gastrodia rhizoma was might have a protective effect on liver injury.

The influence of fertilizer on the growth characteristics in Korean lawn grass was studied from June through October in a experiment. The results were as follows: 1. Maximum dry matter weight of Korean lawn grass was achieved in early in early August when it was $64.3g/m^2$ without fertilizer and $157.9g/m^2$ with fertilizer. On the other hand, the dry matter weight of whole plant including Korean lawn grass reached the maximum in late September, which was late, to some extent, compared with that if pure Korean lawn grass, presumably associated with seed maturing period of $C_4$ type plants. 2. Notable positive effect on leaf blade and non-leaf part weight in Korean lawn grass was also detected. However, the rate of dry matter occupied by non-leaf part was markedly increased by fertilizer application. 3. The dry matter portion occupied by Korean lawn grass the in total dry matter weight of whole plant was significantly decreased as time went by, particularly in case of fertilizer application. 4. Fertilizer, which might imply an increased potential of tiller numbers according to fertilizer. 5. In general, the seasonal change pattern of the rhizome of Korean lawn grass coincided with that of the aboveground organs: Its maximum dry matter weight achieved from late August to early September was $194.2g/m^2$ with nil fertilizer, and, with fertilizer, $259.7g/m^2$, of which figures were equivalent to be increased to 33.7%, compared to that with nil fertilizer. Applying fertilizer increased the weight of root: The highest values were $36.7g/m^2$ with nil fertilizer and $80.9g/m^2$ with fertilizer.
