  • The aim of this research was to investigate the industrial application of Zanthoxylum schinifolium. Antibacterial activities of the n-hexane, methylene chloride (MC), ethyl acetate, and butanol fractions of Z. schinifolium were tested against Escherichia coli, Staphylococcus aureus and Helicobacter pylori. Among the fractions, the n-hexane and MC fractions showed the stronger antibacterial activity against H. pylori, with an inhibition zone greater than 10 mm in disc assays. Further testing of bergapten and lupeol from the MC fraction of Z. schinifolium revealed the antibacterial effects against E. coli, S. aureus and H. pylori, suggesting their potential use as antibacterial agents.

  • The aim of this study is to elucidate the anti-inflammatory activities of chopi (Zanthoxylum piperitum A.P. DC.) essential oil. Essential oil (EO) of chopi was extracted by steam distillation method, and its major constituents were limonene and geranyl acetate. Chopi-EO decreased approximately 38% of nitrite production, as compared to the lipopolysaccharde (LPS)-induced nitrite production. However, chopi-EO and its components did not quench nitric oxide (NO) chemically in cellfree system, and markedly inhibited approximately 40.4% of inducible nitric oxide synthase (iNOS) mRNA transcription. In addition, the inhibition of E-selectin gene transcription by chopi-EO caused the suppression of cellular adhesion. These results suggest that chopi-EO may exert potential anti-immunological inflammatory activity.

  • 본 시험은 약용식물(인진쑥, 오가피, 마늘)의 사료내 첨가가 모돈의 생산성, 포유자돈의 성장율 및 이유자돈에서의 성적 및 혈청 특성에 미치는 영향을 알아보고자 실시하였다. 시험 1은 3~5산차의 임신 모돈 48두를 공시하여 각각 1) CON(basal diet; Control), 2) MP1(basal diet added 0.05% of medicinal plant mixtures), 3) MP2(basal diet added 0.1% of medicinal plant mixtures) 그리고 4) MP3(basal diet added 0.2% of medicinal plant mixtures)로 하여 처리구당 12두씩 배치하여 21일동안 실시하였다. 시험 기간동안 포유모돈의 일당 사료섭취량은 약용식물을 0.1% 첨가한 처리구가 0.2%를 첨가한 처리구보다 유의적으로 높게 나타났다(P<0.05). 포유자돈의 개시시와 이유시의 체중 변화에서는 약용식물을 0.05% 첨가한 처리구가 대조구에 비하여 유의적으로 증가하는 경향을 보였다 (P<0.05). 혈액내 glucose의 함량에서는 MP3 처리구가 대조구에 비하여 유의적으로 높게 나타났다(P<0.05). 시험 2는 개시시 체중 4.70$\pm$0.63kg의 3원교잡종(Landrace$\time$Yorkshire$\time$Duroc) 이유자돈 120두를 공시하여 20일간 사양시험을 실시하였다. 시험설계는 옥수수-대두박 위주의 사료로서 NRC(1998)의 영양소 요구량에 따라 1) CON(basal diet; Control), 2) MP1(basal diet added 0.05% of medicinal plant mixtures), 3) MP2(basal diet added 0.1% of medicinal plant mixtures) 그리고 4)MP3(basal diet added 0.15% of medicinal plant mixtures)의 4개의 처리구로 하여 처리당 6반복, 반복당 5두씩 완전임의 배치하였다. 전체시험기간 동안의 이유자돈의 일당증체량(linear, P<0.067)과 사효효율(linear, P<0.018)에서는 약용식물을 첨가함으로서 증가하는 경향을 보였으며, 사료섭취량(linear, P<0.018)에서는 감소하는 경향을 보였다. 건물의 소화율에서는 약용식물을 첨가함에 따라 증가하는 경향을 보였다(linear, P<0.004; quadratic, P<0.03). 결론적으로 포유모돈 사료내 약용식물의 첨가는 0.1%까지 첨가 급여시가 모돈의 체손실 감소 및 포유자돈의 증체량의 향상을 가져 왔으며, 이유자돈에서는 약용식물을 0.05-1.0% 첨가시 자돈의 성장율 및 건물의 소화율을 개선시키는 결과를 보였다.
