생약재로 사용 중인 Angelica gigas Nakai의 decursin 및 decursinol angelate를 60% ethanol로 최종적으로 추출 후 recycling HPLC 및 HPLC/MS에 의해 각각을 분리하였다. 60% ethanol로 $-20^{\circ}C$에서 추출하였을 경우 95% 순도의 decursin 및 decursinol angelate를 얻을 수 있었고 10번 이상의 recycle를 통해서 순수한 decursin 및 decursinol angelate를 분리할 수 있었다. 분리한 decursin 및 decursinol angelate를 HPLC/MS를 통해 분자량을 확인하였을 경우 m/z=329($[M+H]^+$) 및 m/z=351($[M+Na]^+$)과 같은 결과를 얻을 수 있었다. 이 분리 방법을 통해 decursin 및 decursinol angelate를 통한 의약품 및 식품 등에 관한 여러 연구에 있어 두 물질 각각에 대한 약리학적 효과를 도출하는데 기여할 것이며, 물질표준화에 기여할 것으로 사료된다.

This paper is intended as an investigation of the analysis of high-performance liquid chromatography and the method of extraction of decursin and decursinol angelate in Angelica gigas roots. There are three kinds of extraction methods: distilled water, 50% EtOH and 100% EtOH. The condition of HPLC was obtained on a reversed-phase column $(Polarity\;dC_{18},\;4.6{\times}250 mm,\;5\;{\mu}m)$ using a phosphate buffer-acetonitrile-sodium lauryl sulfate as the mobile phase. Under these chromatographic conditions, UV detector was 230 nm, column temperature $30^{\circ}C$ and the speed of a current 1.0 ml/min, respectively. The results of extraction with distilled water, 50% EtOH and 100% EtOH in Angelica gigas roots were as follows. The concentrations of decursin and decursinol angelate were 182 and 153 ppm (distilled water), 3,142 and 2,547 ppm (50% EtOH) and 3,341 and 2,778 ppm (100% EtOH). There were high positive correlations between the concentrations of decursin and EtOH (r=0.8928, p<0.01) and decursinol angelate and EtOH (r=0.9009, p<0.01).

초고압처리한 신선초 녹즙을 $4^{\circ}C$에서 냉장보관 하면서 미생물의 변화 및 관능적 특성의 변화를 살펴보았다. 초고압처리는 전보에서 최적살균조건으로 계산된 $5700\;kg_f/cm^2$, 7 min의 조건으로 처리하였는데 초기 $8.7{\times}10^6\;CFU/mL$ 존재하던 일반 세균수가 초고압처리 후에는 $3.2{\times}10^3\;CFU/mL$로 감소하여 전보에서 계산된 예상 살균치인 3.44 log cycle 감소에 잘 부합하였다. 특히, 저온저장 식품에 문제가 되는 녹농균이 완전히 사멸하였으므로 저온저장에 유리한 특성을 부여하리라 생각되었다. 대장균 및 대장균군도 완전히 사멸되었다. 관능검사 결과, 밝기와 풀냄새를 제외하고는 초고압처리에 의해 관능특성상의 유의적 차이가 생기지 않았으며, $4^{\circ}C$에서 8일간 저장한 후에는 신선감에서 초고압처리한 녹즙이 유의적으로 높은 점수를 얻었다. 하지만 초고압처리 녹즙에서도 효소적 갈색화로 인한 색도의 변화가 일어나 해결해야 할 문제점으로 부각되었다.

This study investigated on the nutritional components and physiological activity of four wild vegetables namely Salvia plebeia R. Br., Angelica acutiloba, Gynura procumbens and Saururus chinensis Baill for the development of representative wild vegetables in Chungbuk. Salvia plebeia possessed the highest radical scavenging activity and beta-carotene, but exhibited the lowest α-glucosidase inhibitory activity compared to the other three vegetables. Angelica acutiloba showed high crude protein content and α-glucosidase inhibitory activity, but contained low total polyphenol content, radical scavenging ability and beta-carotene compared to the other three vegetables. Gynura procumbens showed high mineral content, beta-carotene, vitamin K1 content and α-glucosidase inhibitory activity, but showed the lowest total polyphenol content and radical scavenging ability compared to the other three vegetables. Saururus chinensis showed high crude fiber content and total polyphenol content, but contained the lowest mineral and vitamin K1 content. To conclude, it is suggested to use Salvia plebeia or Saururus chinensis as antioxidant food materials and Angelica acutiloba and Gynura procumbens as food materials and sources of α-glucosidase inhibitors. In particular, it is believed that Saururus chinensis, which possessed high content of crude fiber, is suitable for low-calorie food materials such as diet products.

누룩치, 고본, 당귀 및 산초의 ethanol ext.는 자발운동량에 미치는 영향에 대한 시험에서 아무런 영향을 미치지 않았다. 다만 phenobarbital sodium 수면시간에 대해서는 산초투여군에서만 다소 단축시켰다. 0.7% acetic acid의 복강내 투여에 의해 유발된 writhing syndrome을 다소 억제하였으나 유의성은 없었다. 체온에 미치는 영향에 대한 시험에서는 유의성 있는 체온 변화가 없었다. 다만 흰쥐의 위액분비에 미치는 영향에 대한 시험에서는 누룩치와 고본투여군에서 위액분비량과 총산도가 유의적으로 감소하였다. 소장운동능에 미치는 영향에 대한 시험결과 누룩치, 당귀 및 고본투여군에서 유의성 있는 charoal의 이동억제가 관찰되었다. 결론적으로 누룩치, 고본, 당귀 및 산초의 ethanol ext.는 일반약리작용에 대하여 특이한 작용이 없었다.

Thirteen compounds were isolated from the roots of Angelica genuflexa through repeated silica gel column chromatography. Nine coumarins, isoimperatorin (1), osthol (2), demethylsuberosin (3), oxypeucedanin (4), heraclenin (5), pabulenol (7), umbelliferone (8), oxypeucedanin hydrate (9) and marmesinin (11), and four chromones, hamaudol (6), cimifugin (10), sec-O-glucosylhamaudol (12) and prim-O-glucosylcimifugin (13), were identified by physicochemical and spectroscopic analysis. Among these, compounds 3, 5, 6, 8, 12, and 13 were isolated for the first time from the roots of Angelica genuflexa. These coumarins and chromones were examined for their anticomplement activity. Demethylsuberosin (3) showed a weak anticomplement activity with an $IC_{50}$ value of $390\;{\mu}M$.

The inhibitory effects of ethanol extract of Radex Angelica uchiyamana, on LPS- or IFN- plus LPS-induced production of NO, and $TNF-{\alpha}$, and expression of iNOS and COX-2 were investigated in the activated RAW 264.7 cells. This extract significantly inhibited the production of NO and $TNF-{\alpha}$, and suppressed the expression of iNOS and COX-2 in a dose-dependent manner. These results show that ethanol extract of Radex Angelica uchiyamana may explain some known biological activities including anti-inflammatory effect, and is of considerable benefit in the treatment for NO and pro-inflammatory cytokine overproduction related immunological diseases.

Essential oil of the root of Angelica koreana Max. (Umbelliferae) was investigated. Essential oil was obtained from the dried roots by steam distillation and fractionated by column chromatography. Each isolate or fraction was identified by GC, GC-MS and spectral analysis. It was found to contain nine monoterpenes such as ${\alpha}-pinene$(7.0%), camphene, ${\beta}-pinene$, myrcene, ${\alpha}-phellandrene$, ${\Delta}-3-carene$, p-cymene, limonene(2.8%), terpinolene and also found to contain m-cresol(11.6%), citronellol, citral b, methylcinnamate, eudesmol and osthol. 2-Hydroxy-5-methylacetophenone and twelve compounds were tentatively identified.
