Coriandrum sativum L., an annual herbaceous plant of Apiaceae family. The present study evaluated the anti-oxidant activities and anti-inflammatory effects of ethanol extracts of C. sativum. The anti-oxidant activities of C. sativum were measured by total contents of polyphenol, flavonoid, DPPH and ABTS radical scavenging and reducing power activity. And anti-inflammatory effects of C. sativum were measured by LPS-induced RAW 264.7 cells. The results showed that the contents of total polyphenol and flavonoid were 76.03 ± 1.36 mg of gallic acid equivalents/g and 182.23 ± 4.32 mg of rutin equivalents/g at concentration 1 mg/ mL of C. sativum. The DPPH radical scavenging activity was found to be 52.8% at 500 μg/mL. The ABTS radical scavenging activity was shown in 58.3% after exposure to 1,000 μg/mL. Reducing power activity was found to be 66.8% at 2,000 μg/mL. The inhibitory effect of NO production was found to be 65% concentration 500 μg/mL. In the generation quantity of inflammatory cytokines such as TNF-α and IL-1β in cell culture medium, the expression levels of inflammatory proteins in cells were showed decrease with the increase of concentration. Therefore, we suggest that the C. sativum should be a potential source of alternative anti-inflammatory drug with good anti-inflammatory effects.

Veronica persica (V. persica) is a perennial plant that is broadly distributed in Europe, Asia and so on. V. persica is used for pain about the lower abdomen and low back. The aim of this study was to investigate the anti-oxidant and antiinflammatory effects of V. persica ethanol extract in LPS-induced RAW 264.7 cells. To evaluate the anti-oxidant activity, the DPPH and ABTS radical scavenging, total polyphenol and flavonoid contents, and reducing power activity were carried out. The DPPH and ABTS radical scavenging activity were evaluated as 72.0% and 73.0% at the concentrations of 200 and 500 μg/mL, respectively. Total polyphenol and flavonoid contents of V. persica extracts were measured as 65.22 mg/g and 43.82 mg/g at the concentration of 1 mg/mL. The reducing power activity measurement showed 53.0% activity at 1 mg/mL. The anti-inflammatory effects of the V. persica extract were evaluated in LPS induced RAW 264.7 cells. In the evaluation of cell viability by proliferation ＆ cytotoxicity assay kit, the cytotoxicity of the extract was not confirmed at 0~800 μg/mL concentration. And the V. persica significantly inhibited NO production in a concentration dependent manner. The inhibition effects of NO in cell medium of V. persica was over 80% at 800 μg/mL. The V. persica also suppressed the expression of iNOS, COX-2, and phosphorylation of NF-κB and IkB-α proteins. These results indicate that the V. persica has anti-oxidant and anti-inflammatory effects by modulating NF-κB signaling pathways and can be used as natural functional materials.

본 논문은 가축의 면역 증진을 위한 천연 첨가제로서 좀민들레의 활용 가능성을 검토하고자 항산화 및 항염증 활성 평가를 실시하였다. 총 폴리페놀 및 플라보노이드 함량은 94.95, 86.33 mg/g으로 나타났고 DPPH, ABTS radical 소거능은 각각 100, 200 μg/mL의 농도에서 50%의 억제율을 보였으며, 1000 μg/mL에서 50%의 환원력을 나타냈다. LPS와 함께 처리한 Raw 264.7 cell에서는 좀민들레에 의한 세포 독성이 나타나지 않았으며 염증 매개 인자 NO와 염증성 사이도카인 IL-1β의 생성량을 유의하게 감소시켰다. 또한 염증성 단백질 발현량을 측정하기 위해 western blotting을 통해 확인한 결과, 400 μg/mL으로 처리하였을 때 LPS 처리구에 비해 염증성 단백질 발현 수준을 유의하게 감소시킨 것으로 확인되었다. 본 연구 결과, 좀민들레 추출물은 세포에 대한 독성이 없이 유의한 항산화 활성과 항염증 활성을 나타냄으로써 가축의 질병예방을 위한 면역 증진 및 생산성 향상에 기여할 수 있는 안전한 대체 천연 첨가제로 이용될 수 있다고 생각된다.

This study was conducted to investigate the growth and physiologycal activitis of Aruncus dioicus var. kamtschaticus (Maxim.) H. Hara under the NaCl treatment conditions (0, 100, 200, 300 mM). After 30 days treatment, the growth and physiologycal activitis were investigated. In the growth of plants, the plant height, leaf width, leaf length and ion level were reduced at NaCl treatments of more than 100 mM. The total polyphenol content was decreased by NaCl in a concentrationdependent manner compared to the control group. The contents of total flavonoids did not show any difference at the concentration of 200 mM and 300 mM. However, the content of total flavonoid decreased compared with that of control. In antioxidant activity, the DPPH and ABTS radical scavenging activity and reducing power activity were decreased by NaCl concentration compared to the control. When changes in the content of NO production was monitored by ELISA, production inhibitory effect was 94.5%, 70%, 63%, 56.9% in NaCl concentration of 0, 100, 200, 300 mM, respectively. The growth, ion level, antioxidant and anti-inflammation activity of Aruncus dioicus var. kamtschaticus was reduced at NaCl treatments of more than 100 mM.

Puff processing is one of the preparation and processing methods of herbal medicines. This study analyzed the quality characteristics in schisandra chinensis extracts by puff processing (1 kgf/cm2, 3 kgf/cm2, 5 kgf/cm2) through changes of the lignan contents and antioxidant activity. The lignan contents and antioxidant activity of puff processing schisandra chinensis extracts (PPSCE) increased higher than compared to a control. Also, as lignan contents and antioxidant activity of PPSCE was increased with the increasing pressure but it was reduced from 5 kgf/ cm2. The results suggest that puff processing was attributed to the quality increase schisandra chinensis.

This study investigated the effect of coated feed using mixed oil on rumen fermentation characteristics. Two experiments were conducted based on materials that were mixed. First, cashew nut and soybean oils were mixed with white mineral oil. And second, different plant extracts were mixed with white mineral oil. At first experiment, inclusion levels of mixed oil on diet (0.03%, 0.1%, 0.5%) were applied as variables. A coated diet was fermented with rumen inoculum according to in vitro rumen fermentation and its parameters were investigated. In the result of first experiment, no negative effects on rumen pH were found. Significantly decreased dry matter digestibility was detected at 0.5% treatment (P<0.05). Total gas productions in control and 0.03% were significantly greater than those of others (P<0.05). Significantly reduced methane productions were found in all treatments compared to the control (P<0.05). Inclusion of mixed oil did not affect on ammonia production. Total volatile fatty acid production was also not influenced by coating with mixed oils. Rumen fermentation parameters were greatly changed according to introduced plant extracts at second experiment. The significantly lowest and greatest ammonia productions were found at treatments with Ixeris dentata and Plantago asiatica, respectively (P<0.05). The significantly greatest acetate and propionate productions were detected at treatments with Crucuma longa and Zizyphus vulgaris 1, respectively (P<0.05). All treatments, except Chrysanthemum idicum, Euyale ferox seed, Moringa leaf and fruit and Zizyphus vulgaris 1, showed significantly increased total volatile fatty acid production compared to the control (P<0.05). Only Paeonia lactiflora showed significantly lesser gas production than the control (P<0.05). In methane production, Ceramium, Zizyphus, Paeonia, Agrimonia, Torilis, Mugwort, Foeniculum, Euphorbia, Taraxacum, Artemisia, Momordica, Curcuma and Moringa reduced methane significantly compared to the control (P<0.05).
