Angelica gigas Nakai (danggui) is a popular herb which has been used as a blood-building decoction for recovery from weakness in the Chinese medicine. Its demand increased in functional foods and pharmaceutical industries. For its hygiene, fumigation has been used, but the use of fumigants are going to be prohibited for food processing. In order to investigate gamma irradiation technique for hygiene of danggui, the immunomodulation activity of danggui after irradiation was examined. The water extract of irradiated danggui showed a strong mitogenic effect on splenocytes in vitro to the same level of lipopolysaccharide (LPS) and phytohemagglutinin (PHA). The effect was not different from that of non-danggui. It was tested whether there was any difference between irradiated and non-irradiated danggui in effects on the secretion of antibodies and graft versus host reaction in vivo. It turned out that intraperitoneal (i.p.) administration of the extract of irradiated danggui for 4 days remarkably increased the number of antibody-secreting cells in mice injected with sheep red blood cells (SRBC). Splenomegaly, due to graft versus host reacton, was also increased after 7 days i.p. administration of the extract of danggui in mice injected with allogeneic splenocytes. In these two in vivo test, the effect were not different from those of non-irradiated danggui. These results indicated that immunomodulation activity of danggui might be preserved after irradiation. In the other experiments (data not shown), the irradiated danggui was stable in active component analysis and safe in genetic toxicity test. In further research, the stability in other physiological activity of irradiated danggui will have to be proved before practical application of irradiation for hygiene.

Root cultures of Angelica gigas Nakai were found to be sensitive to elicitation by poly-saccharide elicitors, such as methyl-$\beta$-cyclodextrin, glucan, carboxymethyl-$\beta$-chitin, chitosan, yeast extract and pectin. For the production of decursinol angelate, ca rboxymethyl-$\beta$-chitin and glucan were found to be the most efficient elicitors. The e nhanced accumulation of decursinol angelate was proportional to the increase of the phenylalanine ammonialyase (PAL) activity after the treatment with most of the elicitors. However, carboxymethyl-$\beta$-chitin treatment did not stimulate the PAL activity, despite the 1.6-fold increase in the decursinol angelate production.

Objectives: The purpose of this study was to investigate the effects of Angelica gigas Nakai extract(AGNE) and Bacillus polyfermenticus KJS-2 (BP2) on atopic dermatitis (AD) induced by 2, 4-dinitrochlorobenzene (DNCB) in mice. Methods: In the experiment, we divided mice into four groups: a control group, a DNCB group, an AGNE group, and an AGNE+BP2 group. Then we examined the changes in scratching frequency, clinical aspects on dorsum skin, immunoglobulin (IgE), cytokines ($TNF-{\alpha}$, IL-6) and expression of COX-2. Resutls: From the experiment, the scratching frequency was significantly dropped in AGNE group and AGNE+BP2 group. Clinical observations of dorsum skin, there were a severe keratotic lesion and drop of dead skin cell in DNCB group, but symptoms of AD were decreased 39.6% in AGNE group and 49.6% in AGNE+BP2 group during 3 weeks. IgE, $TNF-{\alpha}$ and IL-6 were decreased significantly in both AGNE and AGNE+BP2 group. Expression of COX-2 was also decreased significantly in both groups. Conclusions: In conclusion, these data suggest that AGNE can decrease symptoms of AD and BP2 makes AGNE more effective. So AGNE can be useful herbal therapy for AD.

In this study, we assessed the stability and toxicological safety of Angelica gigas Nakai (A. gigas Nakai) extract, which is comprised of decursin and decursinol angelate (D/DA). D/DA was tested for mutagenicity using Ames Salmonella tester strains (TA102, TA1535, and TA1537) with or without metabolic activation (S9 mix). No increase in the number of revertants was observed in response to any of the doses tested (1.25, 12.5, 125, and $1,250{\mu}/mLg$). In addition, a chromosome aberration test was conducted in the Chinese hamster lung (CHL) cell line. To accomplish this, cells were treated with D/DA (3.28, 13.12, 52.46, and $209.84{\mu}g/mL$) or with Mitomycin C ($0.1{\mu}/mLg$) as a positive control in the case of no metabolic activation or benzo(a)pyrene ($20{\mu}g/mL$) in the case of metabolic activation. No significant increase in chromosome aberrations was observed in response to treatment with any of these concentrations, regardless of activation of the metabolic system. According to these results, we concluded that D/DA did not induce bacterial reverse mutation or clastogenicity in vitro in the range of concentrations evaluated in these experiments.

본 연구에서는 참당귀(Angelica gigas Nakai)의 핵심 유효 성분인 decursin과 decursinol angelate를 높은 수율로 추출한 초임계 이산화탄소 선택 추출물의 항염증 효능을 에탄올 추출물과 비교하여 측정하였다. 항염증 효능을 측정하기 위해 염증 매개 인자인 nitric oxide(NO), 염증성 사이토카인인 interleukin(IL)-6, IL-8 생성량을 측정하였다. NO 생성량은 lipopolysaccharide(LPS)로 염증 반응을 유도한 Raw 264.7 세포를 대상으로 Griess assay를 통해 측정하였고, IL-6 및 IL-8 생성량은 tumor necrosis factor(TNF)-α로 염증 반응을 유도한 human keratinocyte cell line(HaCaT) 세포를 대상으로 enzyme-linked immunoadsorbent assay(ELISA)를 통해 측정하였다. NO 생성량은 초임계 이산화탄소 추출물이 에탄올 추출물에 비해 뛰어나게 억제하였다. IL-6 및 IL-8 생성량 또한 에탄올 추출물은 오히려 증가시키는 반면, 초임계 이산화탄소 추출물은 6.25 ㎍/mL의 농도에서 통계적으로 유의하게 억제하였다(P<0.01). 우리는 이러한 결과를 통해 참당귀 초임계 이산화탄소 선택 추출물이 아토피 피부염을 완화시키는 항염증 코스메슈티컬 소재로써 활용 가능함을 확인하였다.

Objectives : We compared with the effects of different parts (root head, root body and hairy root) of Angelica gigas Nakai (Angelicae Gigantis Radix, AG) with on middle cerebral artery occlusion(MCAO)-induced ischemic rats, and on LPS-induced inflammatory response in BV2 microglia. Methods : The 30% ethanol and water extracts of different parts of AG were prepared. Each extract (50 and 100 mg/kg) was administrated intraperitoneally once in MCAO-induced ischemic rats. We measured infarction volumes by TTC staining, and investigated the expression of iNOS, Bax, Bcl-2 and caspase-3 by Western blot. BV2 cells were treated with each extract for 30 min, and then stimulated with LPS. The levels of NO was measured by Griess assay. The expression of iNOS, Cox-2 and proinflammatory cytokines ($TNF-{\alpha}$, $IL-1{\beta}$, and IL-6) were determined RT-PCR and Western blot. The phosphorylation of ERK1/2 and JNK MAPK was determined by Western blot. Results : Among different parts of AG, the 30% ethanol and water extracts of hairy root significantly decreased infarction volume in ischemic brains and inhibited the expression of iNOS, bax and caspase-3. The extracts of hairy root significantly inhibited LPS-induced production of NO, $TNF-{\alpha}$ and IL-6 in BV2 cells, and suppressed the expression of iNOS and COX-2. The hairy root extracts attenuated LPS-induced phosphorylation of ERK1/2 and JNK MAPK in BV2 cells. Conclusions : Our results indicate that the root hairy of AG has a good neuroprotective and anti-inflammatory effects in ischemic stroke compared to other parts.

Background: The Korean name for Angelica gigas Nakai (AGN) is Cham-dang-gui, which grows naturally or is cultivated, and its dried roots are used in traditional herbal medicines. The AGN root exert various pharmacological effects. Despite the various pharmacological effects of the AGN root, there are no reports on its anti-oral microbial effects. The purpose of this study was to reveal the anti-oral microbial effect and the microbial and biochemical changes in oral microorganisms according to the concentration of the ethanol extract of AGN (EAGN) root, and to confirm the possibility of using EAGN as a plant-derived functional substance for controlling oral infectious microorganisms. Methods: Disk diffusion test, growth measurement, biofilm formation assay, and measurements of acid production and buffering capacity were performed to confirm the antibacterial effect of EAGN. Results: EAGN showed anti-oral bacterial effects against Streptococcus mutans and Aggregatibacter actinomycetemcomitans at all concentrations, with S. mutans showing a more susceptible effect at concentrations above 5.0 mg/ml and A. actinomycetemcomitans at 3.75 mg/ml. EAGN treatment significantly reduced A. actinomycetemcomitans growth at all concentrations tested. Biofilm formation was significantly reduced at concentrations above 3.75 mg/ml for S. mutans and 2.5 mg/ml for A. actinomycetemcomitans. Acid production in S. mutans and A. actinomycetemcomitans was significantly increased by treatment with EAGN, and the buffering capacities of S. mutans and A. actinomycetemcomitans increased from an EAGN concentration of 3.75 mg/ml and above. Conclusion: EAGN showed anti-oral bacterial effects against both S. mutans and A. actinomycetemcomitans at concentrations above 3.75 mg/ml, which were thought to be related to the inhibition of their growth and biofilm formation. Therefore, EAGN can be used as a safe functional substance derived from medicinal plants owing to its antibacterial effects against S. mutans and A. actinomycetemcomitans.

참당귀(Angelica gigas Nakai)를 기능성 식품소재 및 의약품의 원료로 활용하기 위하여 참당귀 methanol 추출물에 대한 항산화, 항암 및 면역활성을 조사한 결과는 다음과 같다. 참당귀의 항산화력을 알아보기 위하여 0.1, 0.5 및 1 mg/mL의 농도로 당귀의 methanol 추출물을 처리한 후 수소 공여능, 환원력 및 hydroxyl radical 활성을 측정하였다. 그 활성은 모두 추출물의 농도에 의존적으로 높게 나타났으며, 특히 수소공여능은 1 mg/mL에서 대조군과 비교했을때 50% 정도의 활성을 나타내었다. 참당귀 methanol 추출물을 SW480세포에 처리한 결과 대조군에 비하여 농도 의존적으로 암세포의 성장을 억제하였으며, 암세포에 참당귀 methanol 추출물을 24시간 처리하여 hoechst 염색한 후 형광현미경으로 관찰한 결과 핵의 응축 및 DNA 분절이 관찰되었다. 또한 참당귀 methanol 추출물이 처리된 암세포에서는 대조군에 비하여 농도에 의존적으로 caspase-3의 활성이 증가하였다. 참당귀의 methanol 추출물은 생쥐의 비장으로부터 분리한 면역세포에 대하여 대조군과 비교하여 상이한 차이를 보이지 않았으며, 또한 대식세포인 RAW 264.7에서도 $NO_2$(Nitrite)를 함량이 증가되지 않았다. 따라서 이들 결과는 참당귀 methanol 추출물은 약한 항산화 활성을 가지며, 면역 활성에는 큰 관련이 없지만, SW480 암 세포에서 caspase dependent pathway에 의한 apoptosis를 유도함으로서 암세포의 사멸하는 것으로 판단되어진다.
