  • The effect of water dropwort (Oenanthe javanica DC) extract in eliminating ethanol was evaluated in New Zealand white rabbit and ICR mice. When a hot-water extract of water dropwort extract and ethanol was injected into New Zealand white rabbit, the plasma ethanol level was rapidly reduced, similar to metadoxine treatment. Specifically, the n-butanol fraction of hot-water extract was the strongest in eliminating plasma alcohol in ICR mice. When ethanol was orally ingested, administration of the hot-water extract eliminated up to 44% of the plasma ethanol in mice while the n-butanol fraction eliminated around 70%. Alcohol removal behaved in a dose-dependent manner in response to 50-200 mg/kg of n-butanol fraction. These data show O. javanica extract is effective in overcoming alcohol intoxication by the accelerating ethanol metabolism.

  • 미나리의 엽조직을 agroinfiltration 및 동시배양을 수행하기 전에 NaOH 용액에서 3 min 처리를 실시하였다. MTT를 이용한 세포사멸실험에서 0.7% NaOH 용액처리까지는 엽조직 세포활성에 안전한 것으로 판단되었다. GUS 효소활성의 형광분석 결과 0.5% NaOH를 처리한 미나리 엽조직에 대하여 Agrobacterium cells ($OD_{600}=0.5$에서 1.0)을 이용한 vacuum infiltration (20 min)을 실시할 경우 효율적 형질전환이 이루어짐을 알 수 있었다. 이러한 조건은 western blotting과 ELISA에 의한 HBsAg의 발현 검정에서 확인할 수 있었다.

  • Background: This study aimed to investigate the effects of Oenanthe javanica (OJ) extracts on rats with potassium oxonate (PO)-induced hyperuricemia. Methods: The effects of OJ extract on rats with PO-induced hyperuricemia-induced were monitored. Changes in the body weight and organ indices of hyperuricemic rats were calculated to detect anti-hyperuricemic effects. Blood samples were collected to observe the effect of reducing serum uric acid concentration. Kidney tissues were stained to observe histopathological changes under a microscope. The activity of xanthine oxidase (XO), which catalyzes xanthine to uric acid in the liver, was assessed to observe the inhibitory effect of XO. Results: 1. The body weight of hyperuricemic rats showed no considerable differences between the control group and the treatment group. The OJ group had significantly improved liver index, whereas the allopurinol group had improved liver and kidney indices. 2. Serum uric acid levels increased significantly after PO injection, and the OJ and allopurinol groups showed a significant reduction effect. 3. PO injection led to the inflammation of kidney tissues, and OJ improved it significantly. 4. The activity of XO after PO injection was significantly increased, and allopurinol significantly inhibited XO activity in the liver. Conclusion: In the hyperuricemia rat model, OJ extract reduced uric acid concentration and demonstrated its anti-inflammatory effects. Thus, OJ extracts can be used to lower uric acid levels.

  • Isorhamnetin isolated from Oenanthe javanica significantly inhibited proliferation and collagen production in HSC-T6 cells in concentration- and time-dependent manners. Pretreatment of HSC-T6 cells with isorhamnetin significantly inhibited serum-induced ERK phosphorylation, in a similar manner as PD98059, a known MEK inhibitor. These results suggested that isorhamnetin reduced collagen production in HSC-T6 cells, in part, via inhibition of ERK signaling pathway.

  • The anti-inflammatory and analgesic action of the components isolated from some edible plants carried out. We isolated the quercitrin, compound 3 and o-counmaric acid from Cedrela sinensis, Oenanthe javanica and Artemisia princeps var. Orientalis respectively. O-coumaric acid showed the inhibitory effect on carrageenin-induced edema as well as vascular permeability in mice. And we also found the analgesic activity in all compounds isolated from these plants.

  • This studies were conducted in an attempt to investigate the effect of Oenanthe javanics extract on enzyme activities of liver and excretory action of bile juice in serum of carbon tetrachloride-intoxicated rabbits. Long-term oral administration of this extracts shows more rapid recuperation in GPT, total cholesterol, alkaline phosphatase, total bilirubin and BSP values than control groups. 750 mg/kg-administered group shortens rapidly the recovery time o·』 GPT, total cholesterol and BSP values than 250 mg/kg administered groups. But any difference was not observed in alkaline phosphatase, bilirubin among two groups. In histological studies the lager amount-administered groups exhibited more rapid recovery of liver cell enlargement, oedema, necrosis in carbon-tetrachloride treated rabbits.

  • The composition of essential oil from O. javanica was analyzed by gas chromatography-mass spectrometry. Using the broth dilution method and disk diffusion test, anti-microbial activities of the oil fraction and its main components were evaluated against various antibiotic-susceptible and resistant strains of pathogenic microorganisms. As a result of GC-MS analysis, 57 compounds, including ${\alpha}-terpinolene$ (28.1%), dl-limonene (16.0%), ${\gamma}-terpinene$ (10.3%), ${\beta}-pinene$ (9.7%) and ${\alpha}-pinene$ (6.0%) were identified in the essential oil fraction. The essential oil fraction of O. javanica and its main components exhibited significant inhibitory activities, particularly against Candida albicans (antibiotic-susceptible strains) and Streptococcus pneumoniae (antibiotic- susceptible and resistant strains). The main components of the O. javanica oil fraction displayed different patterns of activity against the three tested Candida species as exemplified by the differential minimum inhibiting concentration (MIC) values. The disk diffusion test showed that the activities were dose dependent.

  • Nitrogen(N) and phosphorus(P) in surface streams mainly lead to euthrophication. It aggravates water quality and consequently increases the purification costs. As a resolution of water contamination caused by household drainage through irrigation route by 70% of the 1,300 community residents in Eum-Am Myun, Seo-San city, was implemented biological self-purification method by growing Oenanthe Javanica along the polluted water tunnel. The contaminated water was efficiently purified after passing the dropwort field; DO conc. of effluent water was increased 8.3∼61.9% after through the drop wort field. HRT of experiment system was changed 0.05∼1.50/day. 50% of BOD was eliminated at the range above 12 mg/l of Influent BOD conc. Also, 50% of COD was eliminated at the range above 30 mg/l of Influent COD conc. Finnally, the influent T-N loading at range below 1.5 g/m$^3$/d reduced 50% of Influent T-N conc., and so did influent T-P loading at the range below 0.03 g/m$^3$/dwas reduced 50% of Influent T-P conc.

  • Chemical properties of the different parts of watercress(Oenanthe javanica D.C.) grown and harvested from the culture fields under different cultivating methods were studied. In proximate analyses of watercress in parts, moisture contained more in stem than in root or in leaf, but crude protein and crude lipid contents were lower in stem than in root or in leaf. Crude ash in root contained up to about double amount in leaf or stem. Major mineral elements detected in watercress were Fe, Mg, Ca, and K, and their contents in root was higher than those in stem or leaf. Especially, Fe in root was significantly higher than that in stem or in leaf. Total free sugar composed mainly with fructose and glucose, was the highest in watercress from Hwasoon and followed the watercress from Jeonju and Donggok in order. Free sugar content was highest in leaf and the lowest in root. Major water-soluble vitamins were vitamin C, thiamin and biotin and the content of vitamin C was higher than others. These vitamins contained more in leaf than in stem or root. Niacin contained 6.09 mg/100 g in leaf of watercress from Hwasoon, which was much higher than others, but it was not detected in stem of watercress from Jeonju. Organic acids detected were oxalic acid, citric acid and malic acid and other 12 organic acids were not detected. In fatty acid composition, there were significant differences among watercresses from different parts and different culture fields. Linoleic acid, linolenic acid and palmitic acid were major fatty acids contained in watercress and it took about 80% of the total content. Amino acid content in leaf was higher than that in root and in stem. Glutamic acid and proline were major amino acids in stem of watercress from Jeonju and in stem of watercresses from Hwasoon and Donggok, respectively. In leaves of all three watercresses glutamic acid content was the highest.
