  • 가시오갈피 및 두충과 같은 천연 생리활성 사료 첨가제를 사료와 함께 급여하여 지방, 근육, 항산화 효소 등과 관련된 유전자의 발현을 분석하여 생리활성 물질에 의한 육계의 영향을 분자생물학적 측면에서 접근해 보고자 본 연구를 실시하게 되었다. 본 연구는 육계 Ross종 수컷을 5처리 8반복, 반복당 4수씩을 4일령에 완전 임의 배치하였으며, 시험 사료에 가시오갈피와 두충을 0%(대조구), 0.5%, 1% 수준으로 각각 첨가하여 35일령까지 자유 급여를 실시하고 시험 종료일에 근육과 간의 조직을 취하여 RNA를 분리한 후 분석에 이용하였다. 천연물 첨가에 따른 증체, 사료 섭취량 및 사료 요구율의 사양 성적 결과, 사료 요구율을 제외한 사양 성적에 큰 영향을 미치지 않았다. 근육 및 지방 합성 관련 유전자의 발현을 분석한 결과, 지방 합성 관련 유전자 FAS는 처리간에 차이가 없었으나, 전사인자인 $PPAR{\gamma}$의 유전자 발현은 두충 처리구에서 높은 발현을 보였으나, 대조구와 가시오갈피와는 차이가 없었다. 근육 관련 유전자 MyoD와 Myogenin의 발현을 분석한 결과, Myogenin은 모든 처리구에서 대조구에 비해 높은 발현율을 보였으며, MyoD 또한 대조구에 비해 높은 발현율을 보였으나 가시오갈피에 비하여 두충이 이 유전자의 발현을 더 유도하는 것으로 나타났다. 항산화 효소 유전자(GST, CAT, SOD, GPX)의 발현을 측정한 결과, 대체적으로 대조구와 큰 차이가 없었으나 두충의 1% 사료내 첨가는 항산화 효소 중 SOD와 GPX의 활성을 증진시켰다. 이상의 결과로부터 육계에 가시오갈피와 두충의 급여는 생산 능력에 큰 영향을 미치지 않으면서 근육 성장에 긍정적으로 작용하여 산화적 스트레스도 감소(SOD, GPX)시키는 효과가 있는 것으로 사료된다.

  • The radix and folium of Eucommia ulmoides(Eucommiaceae) has been used for backache, atrophy of the leg and knee, enuresis, hypertension. In order to evaluate to quality of folium, we have been isolated a main compound as a standard compound, which was elucidated $quercetin-3-O-{\beta}-D-xylopyranosyl(l{\rightarrow}2)-{\beta}-D-glucopyranoside$ through it's physicochemical data and IR, FAB-Mass, $^{13}C-NMR$ and $^{1}H-NMR$ analysis. It was analyzed by HPLC system using 17% $CH_3CN$ as a solvent system. The amount of $quercetin-3-O-{\beta}-D-xylopyranosyl(l{\rightarrow}2)-{\beta}-D-glucopyranoside$ from Eucommiae folium was in the range of $0.056{\pm}0.022$ mg(n=7) and also from the results of analysis through seasonal variation$(June{\sim}October)$ September and October have been evaluated to be very high in it's content.

  • The pharmacological activities on water extracts of Cortex, Ramulus and Folium from the Eucommia ulmoides Oliver were studied, and the following results were observed. The vasodilative action on the rabbit ear blood vessel was recognized in the Cortex, Ramulus and Folium. The spontaneous motility and the contraction induced by Ach., $BaCl_2$ and histamine in the isolated ileum of mice were suppressed and inhibited in the Ramulus only. On the contrary, the analgesic and anti-inflammatory activities were noted in the Cortex and Folium. Furthermore, the hypotensive effect was recognized in the Folium. The diuretic, bile secretory and anti-fatigue effects were shown in the Cortex and Folium.

  • Geniposide, an iridoid glucoside, was isolated from the cortex of Eucommia ulmoides by repealed silica gel chromography and identified by its spectral data. The quantitative determination of geniposide with HPLC has been developed and this method provided a tool for standardization of the commercial Eucommiae Cortex.

  • A bioassay-guided fractionation of the stem bark extract of Eucommia ulmoides Oliver (Eucommiaceae) led to the isolation of three iridoid constituents, genipin (1), geniposide (3), geniposidic acid (4) as well as (${\pm}$)-guaiacylglycerol (2) and fatty acid mixtures as active ingredients of the extract responsible for the antitumoral property. The EtOAc soluble part and BuOH soluble part of the extract demonstrated a significant inhibition on the proliferation of cultured human tumor cells such as A549 (non small cell lung), SK-OV-3 (ovary), SK-MEL-2 (melanoma), XF498 (central nerve system) and HCT-15 (colon) in vitro, whereas the remaining water soluble part exhibited a poor inhibition.

  • The anti-diabetic effects of the methanol extracts of Cortex, Ramulus and Folium part of Eucommia ulmoides Oliver were investigated by the experimental diabetic model in rats. The increased blood glucose level in the diabetic rats induced by alloxan and streptozotocin was significantly lowered and a marked increase in body weight was shown with the treatments of the extracts of Cortex and Folium. The blood insulin level lowered by streptozotocin pretreatment was significantly recovered with the treatment of the extract of Folium. In glucose tolerance test, the extracts of Cortex and Folium displayed a significant inhibitory effect on the glucose level. The extracts of Cortex and Folium also caused a marked inhibition in increased blood pressure in the diabetic rats induced by alloxan.
