Peroxidase as one of the organic enzyme catalyst is useful for the oxidation treatment of various aromatic compounds such as phenols. The peroxidase content of Oenanthe javanica was 24.85 unit/g-fw in leaf, 5.74 unit/g-fw in stem, and 34.69 unit/g-fw in root respectively. The crude peroxidase extracted from Oenanthe javanka can be kept under low temperature (-70$\circ$C) condition for 6 months with the maximum 1% activity reduction. The optimum conditions of removal for 100 ppm phenol was pH 6, hydrogen peroxide 3.5 mM, peroxidase activity 8 unit/ml, temperature 20$\circ$C respectively. In the wide range of concentration from 50 ppm to 750 ppm phenol reveals average 54% removal rate under the same peroxidase activity (8 unit/ml) and different amount of hydrogen peroxide proportional to phenol concentration. Especially at the concentration of 100 ppm the maximum phenol removal rate was 72%.

흑마늘 음료의 기호성과 기능성 증진을 위해 흑마늘과 미나리의 배합비를 각각 3:0(BD-1), 2:1(BD-2), 1:1(BD-3), 1:2(BD-4)의 비율(w/w)로 달리하여 제조한 음료의 식품학적 특성과 항산화 활성을 비교 검토 하였다. 흑마늘 미나리 혼합음료의 pH는 미나리 첨가량이 증가함에 따라 증가하였으나, 당도는 감소하는 경향을 나타내었다. 색도는 L값과 b값은 유의적인 차이를 보이지 않았으나, a값은 미나리 첨가량이 증가함에 따라 2.40(BD-1)에서 6.46(BD-4)로 증가하였다. 폴리페놀 함량은 BD-4에서 46.96 ${\mu}g/mL$으로 가장 높게 나타났으며, BD-3(42.36 ${\mu}g/mL$), BD-2(41.91 ${\mu}g/mL$), BD-1(28.48 ${\mu}g/mL$) 순으로 나타났다. SOD 유사활성은 BD-4에서 18.60%으로 가장 높은 활성을 나타내었으며, BD-3(15.53%), BD-2(12.53%), BD-1(10.27%) 순으로 활성을 나타내었다. ABTS 라디칼 소거능은 BD-1에서 28.72%로 가장 낮게 측정되었으며, 미나리 첨가 비율이 증가함에 따라 유의적으로 증가하여 BD-2는 39.43%, BD-3은 45.69%, BD-4는 52.51%로 나타났다. 철 이온 킬레이트 효과는 미나리 첨가량이 증가함에 따라 증가하였으며, BD-1(6.38%)에 비해 BD-4(39.94%)에서 6배 높게 측정되었다. 수용성 비타민(B1, B2, B6, C) 함량은 미나리 첨가량이 증가함에 따라 증가하는 경향을 나타내었으며, 특히 비타민 C의 경우 BD-1(130.10 ${\mu}g/mL$)에 비해 BD-4(806.21 ${\mu}g/mL$)가 6배 가량 증가하였다. 관능검사의 경우도 색, 향, 맛, 종합적 기호도에서 BD-4가 가장 양호하였다. 이러한 결과를 종합해 보면, 흑마늘 미나리 혼합 음료를 제조할 경우 흑마늘과 미나리를 1:2 비율(w/w)로 혼합하는 것이 생리활성과 관능적 품질 특성 측면에서 우수할 것으로 사료된다.

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.

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.

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.

The hepatoprotection by the methanol extract of Oenanthe javanica DC (water dropwort) (OJME) was investigated in Sprague Dawley rats with inducing liver damage by acetaminophen. After OJME administration for 1 week, the increase of hepatic lipid peroxide level by acetaminophen-induced hepatotoxicity was significantly reduced. In case of phase I microsomal enzyme systems including cytochrome P-450, aminopyrine N-demethylase and aniline hydroxylase, any significant differences between in control and in OJME-pretreated group was observed after acetaminophen treatment. However, the pretreatment of OJME maintained the hepatic glutathione level and the activity of liver cytosolic glutathione S-transferase, which was significantly decreased by the acetaminophen intoxication. Among the glutathione-generating system, glutathione reductase was more responsible for its biosynthesis rather than ${\gamma}-glutamylcystein$ synthetase. OJME itself showed the strong inhibition activity on DPPH radical generation. In conclusion, OJME administration maintains the liver glutathione pool and hepatic glutathione S-transferase activity, in addition with its high anti-oxidative capability, to show hepatoprotective effect from acetaminophen intoxication.

본 연구에서는 신선초 녹즙과 돌미나리 녹즙을 다양한 실험을 통하여 산화방지 활성을 측정하였다. DPPH 라디칼, NO, $O_2{^-}$, ${\cdot}OH$ 라디칼 소거능 실험을 이용하여 유기농 및 일반농 신선초 녹즙과 돌미나리 녹즙의 산화방지 활성을 측정해 본 결과, 모든 시료군에서 높은 라디칼 소거 활성이 나타났다. 또한, 산화적 스트레스에 민감한 LLC-$PK_1$ 세포를 이용하여 유기농 및 일반농 신선초 녹즙과 돌미나리 녹즙의 산화적 스트레스 개선 효과를 살펴본 결과, 신선초 녹즙과 돌미나리 녹즙은 AAPH, SNP, 파이로갈롤과 SIN-1에 의해 유발된 산화적 스트레스(NO, $O_2{^-}$와 $ONOO^-$)에 대한 세포 생존율을 증가시키고, 지질과산화를 억제시켜 라디칼에 의한 산화적 스트레스에 대한 개선 효과가 뛰어난 것으로 사료된다. 이상의 결과로부터 신선초 녹즙과 돌미나리 녹즙은 우수한 산화방지 활성과 지질과산화 개선 효과를 나타내어 신선초 녹즙과 돌미나리 녹즙으로부터 산화방지 영양소를 충분히 섭취하는 것이 산화적 손상과 관련된 질병을 예방하는 좋은 방법이 될 수 있을 것이라 사료된다.

To evaluate the phylogenetic and taxonomic status of the phytoplasmas associated with water dropwort (Oenanthe javanica DC) disease in Korea and Japan, their 16S rDNA was analyzed. DNAs extracted from water dropworts collected in Korea (Kyongnam province) and Japan (Chiba prefecture) affected by witches' broom and yellows were subjected to PCR using phytoplasma-specific primers, which amplified a 1.4-kbp fragment that included the 16S rDNA. Phytoplasmas were characterized by RFLP analysis using AluI, HaeIII, HhaI, KpnI, MseI, and RsaI restriction enzymes and by sequence analysis of the PCR products. The mater dropwort witches'broom (WDWB) and water dropwort yellows (WDY) 16S rDNA sequences were identical and closely related to onion yellows (OY, 99.9% identity), which belong to the aster yellows (AY) 16S-subgroup. However, the KpnI RFLP analyses clearly distinguished the WDY and WDWB phytoplasmas from the OY phytoplasma. The phylogenetic analysis based on 16S rDNA showed that WDWE and WDY phytoplasmas are members of a relatively homogeneous group that evolved from a common ancestor.
