Scab disease of Aralia elata (Miq.) Seemann occurred severely in Kangwon province, Korea. First, brown spots were formed on leaves and enlarged along vein. The infected leaves including petiole and midrib were twisted forming scab and died eventually. Also the disease infected twigs and trunks of the tree forming scab. Conidia, ascospores and asci developed in locule were observed in the infected tissue. The causal organism of the scab disease of Araliae elata was isolated and identified as Elsinoe araliae Yamamoto (imperfect stage: Sphaceloma araliae Jenkins) based on the morphological and cultural characteristics, and pathogenic test.

This study has examined the effects of Aralia elata Seemann ethanol extract on antioxidant enzyme systems inrats along with benzo($\alpha$) pyrene(B(a)P) administration . The ethanol extract of Aralia elata Seemann (50mg/kg body wt.) was fed to rats for 4 weeks by stomach tubing. The extract administration increased antioxidant activities of glutathione sulfur transferase(GST) comparing to the control. also total superoxide dismutase(SOD) and Cu, Zn-SOD activities were stimulated. Catalase activities were increased by 50% with the extract feeding compared to the control . Combined administration of B($\alpha$)P and the extract increased GST activity in B($\alpha$) P group. Although total SOD acitivity was decreased , Cu, Zn-SOD was greately increased from 0.10unit to 0.18 unit and catalase activity also was increased compared to the group of B($\alpha$) P. GST activity in CLE group was 1.32 unit, increased by 33% comparing to the group CL of 0.99unit. Cu, Zn-SOD and catalase activities in thegroup fed high fat and ethanol extracts were increased by 25% and 39%, respectivley comparing to the group of high fat. In addition , total SOD was decreased but, Cu, Zn-SOD acitivity was increased from 0.09 unit to 0.18unit. Catalase activity was 76.05 unit in the group of B($\alpha$) P and extract comparing to 65.26 units in B($\alpha$)P group. Serum $\alpha$-tocopherol of rat was markedly increased by theextract. Administration of B9$\alpha$)P reduced $\alpha$-tocopherol levels in the serum, on the other hand, lard in the diet increased $\alpha$-tocopherol levels in the serum. The above results indicate that Aralia bud exerts antioxidant functions in vivo against B($\alpha$)P. Further research may be necessary for the identification fo the biologically active material.

Objectives : The trunk-bark and the root of A. elata were compared with each other in terms of their anti-oxidative activities. Methods : Using the trunk-bark and the root of A. elata, their anti-oxidative activities were examined through the in vitro and in vivo experiments. Results : The trunk-bark of A. elata in vitro had weaker anti-oxidative activities than its root. However, the trunk-bark of A. elata in vivo had stronger anti-oxidative activities than the root in the rats which was oxidatively stressed by alcohol. Conclusion : These results suggested that the trunk-bark of A. elata was also useful as a medicine.

개별인정형 건강기능식품 기능성 원료로 개발한 두릅추출물의 표준화를 위해 항고혈압활성 효과를 가지고 있는 기능성분 HE를 지표성분으로 설정하고, HPLC/UV 방법을 이용하여 기능성분 분석법을 확립하며 그에 따른 유효성 검증을 실시하고자 하였다. 유효성 검증 결과, 본 시험법에서 표준용액의 피크유지시간과 두릅추출물의 피크유지시간이 일치하였다. 검량선의 결정 계수(R2)는 0.9999 이상의 높은 직선성을 보여 분석에 적합함을 알 수 있었으며, 검출 한계는 $12.0{\mu}g/mL$, 정량한계는 $36.5{\mu}g/mL$로 두릅 추출물 중의 HE 함량분석을 위한 충분한 한계 수준으로 확인되었다. 정확성에서 $98.8{\pm}0.865-104.7{\pm}2.536%$로 높은 수준의 HE 회수율을 보였으며, 평균 분석오차는 0.013%로서 기준인 10% 이내를 만족하였다. 또한 반복성에서는 평균 $101.5{\pm}0.4%$로 RSD 0.4%를 나타내었고, 실험실내 정밀성에서 RSD 0.2%, 완건성에서 RSD 0.2%를 나타내어 모두 적합함을 확인하였다. 한편, 제주산 두릅추출물 중에는 기능성 지표성분인 HE가 4.88% 함유되어 있는 것으로 확인되었다. 이상의 실험 결과, 두릅추출물의 항고혈압활성 기능성분인 HE의 HPLC/UV 분석방법은 특이성, 직선성, 정확성, 정밀성, 반복성, 완건성 등의 모든 항목에서 validation 기준에 적합한 시험 방법으로 확인되었다.
