Objectives : This research was observed by examining the external and internal parts and the quantity of the surface components of the wild type and cultivar of Angelica dahurica in korea. Methods : The slice of the tested material mede by paraffin section technique was colored with Safranine Malachite Green contrast methods, and then observed and photographed by the microscope and examined the quantity of the surface components. Results : In the shape of the roots, the wild type had a very thin main root and 2 long roots, while the cultivar had a long root branched out from the short and thick main root making a square pyramid shape. Isoimperatorin was detected at Rt $17{\sim}18$ minutes. The wild type contained 0.56% while the cultivar contained it of 0.355%, thus the component of the wild type was about 1.5 times of that of the cultivar. Conclusions : It was thought that there might be also some differences in their genetic characteristics, etc.

This study is carried out to evaluate the genotoxicity of herbs (Angelica decursiva, Polypori umbellate, Astragalus membranaceua, Paeonia iactiflora, Glycyrrhiza uralensis, Cnidium officinale, Rehmannia glutinosa, Cyperus rotundus, Dioscorea batatas and Platycodi Radix) by using the Ames test. The Salmonella typhimurium reversion assay is being performed by using the Sal. typhimurium TA98, TA100, TA102, TA1535 and TA1537 as tester strains. Among 70% of ethanol extracts from 10 herbs, the number of revertant colonies is being increased in Astragalus membranaceua, Cnidium officinale and Dioscorea batatas in a dose-dependent manner, as compared with negative controls of the metabolic activation. In case of dichloromethane and ethyl acetate fraction from 70% of ethanol extracts, the number of revertant colonies is increased in Angelica decursiva, Astragalus membranaceua, Cnidium officinale, Rehmannia glutinosa and Dioscorea batatas in a dose-dependent manner, as compared with negative controls of metabolic activation. Such results indicate that Angelica decursiva, Astragalus membranaceua, Cnidium officinale, Rehmannia glutinosa and Dioscorea batatas all show genotoxic effects when being extracted with the solvent extractions such as 70% of ethanol, dichloromethane and ethyl acetate, and thus, they might be genotoxically- non-safe.

Radix Angelicae Gigantis is sweet and pungent in flavor, warm in property. Its effects are tonifying the blood, promoting blood circulation, relieving pain and moistening the bowels. Its indications are blood deficiency syndrome characterized by sallow complexion, dizziness, irregular menstruation, amenorrhea, pains due to blood stasis, and rheumatic arthralgia. Using genes of A. gigas, A. acutiloba, and A. sinensis, the origin of which is identified, as criteria, we analysed many kinds of Angelica with RAPD and RFLP on ITS region, in order to compare and discriminate genes extracted from crude drugs ‘Dang-gui’, that are produced in Korea on the one hand and imported on the other hand. We reached the following conclusion. 1. We could extract DNA from both original plant and dried plant. 2. Especially Uniprimer #1, Uniprimer #2, Uniprimer #4 and Uniprimer ＃9 were useful. 3. Among the restriction enzymes Sma I, Msp I, Hae III, and Hinf I, used in this experiment, four restriction enzymes except Hinf I could be used properly in discriminating all samples used as A. gigas. We think that this result can be used as a method of discriminating crude drug of Angelica L. related drugs, and used in controlling quality and circulation.

본 연구는 백지 에탄올추출물의 항산화 활성을 알아보기 위하여 총 포리페놀 함량, 총 플라보노이드 함량, 전자공여능을 독립적으로 3회 이상 반복 실시하여 측정 하였고, brown guinea pig(450~500g)의 등 부위에 1500mJ/$cm^2$ 광량의 자외선 조사로 유발시킨 피부(6areas per group)에 1일 2회, 주 5일, 매회 $30{\mu}{\ell}$씩 총 5주간 시료를 도포한 후 염산 케타민으로 마취, 시료를 도포한 피부 부위를 직경12mm의 biopsy punch로 절취하여 10%의 중성 포르말린 용액에 12시간 실온에서 고정한 후 Hematoxylin and eosin(H&E) 염색으로 표피 및 진 조직을 관찰하였다. 백지 에탄올추출물의 총 폴리페놀 함량과 총 플라보노이드 함량을 측정한 결과, 각각 20.7mg/g, 19.5mg/g으로 확인되어 항산화물질 함량이 양호하게 나타났다. 전자공여능을 측정한 결과, 백지 에탄올추출물은 농도가 증가함에 따라 전자공여능 또한 유의하게 증가하였고, $500{\mu}g/m{\ell}$과 $1000{\mu}g/m{\ell}$농도에서 각각 14.8%, 19.8%의 전자공여능을 보여 양성대조군으로 사용한 Dibutylated hydroxytoluene(BHT)보다 공여능이 낮았으나 의미 있는 항산화 효과를 보였다. H&E 염색 결과, 대조군의 표피에서 경미한 비후도가 나타났으나, 백지 에탄올추출물 도포군은 피부조직 배열이 규칙적이며 염증관련 세포 침윤 등의 별다른 이상 징후는 발견되지 않았다. 이상의 결과를 종합하면 백지 에탄올추출물은 천연 항산화제로서 이용가치가 있을 것으로 판단된다.

The hexane and ether extracts from the roots of Angelica dahurica caused a significant inhibition of hepatic drug-metabolizing enzyme (DME) activity. Through systematic fractionation by $SiO_2\;column$ and vacuum liquid chromatography monitoring by bioassays, three furanocoumarins, phellopterin, byakangelicin and tert-O-methylbyakangelicin were isolated as active principles. These components have biphasic responses, both inhibitory and inducing effects on DME system. Tert-O-methyl byakangelicin was found to have the strongest enzyme inhibitory potency.

Anglicae dahuricae Radix (ADR), the dried roots of Angelica Dahurica Benth et Hook (Umbelliferae), is a traditional herbal medicine used to treat colds, headache, skin diseases such as acne and possess analgesic, antipyretic and drainage effects. In the present study, the author evaluated the effect of ADR on regulation of inflammatory reaction. ADR reduced the ear-swelling responses derived from compound 48/80 in dose-dependent manner significantly. ADR inhibited the PMA plus A23187-induced productions of IL (Interleukin)-8, IL-1β, granulocyte macrophage-colony stimulating factor (GM-CSF) and tumor necrosis factor (TNF)-α from human mast cells (HMC)-1. In addition, ADR blocked PMA plus A23187-induced ERK1/2 phosphorylation. Ⅰ suggest that ADR regulates inflammatory reaction through inhibition of inflammatory cytokines such as IL-8, IL-1β and GM-CSF.

Objectives : This study was designed to investigate the collagen metabolism and tyrosinase activity of Angelicae Gigantis Radix extracts (AGR). Methods : The effect of AGR on type I procollagen production and collagenase activity in human normal fibroblasts HS68 after UVB (312 nm) irradiation was measured by ELISA method. The tyrosinase activity after treatment of AGR was measured. Results : Type I procollagen production was recovered by AGR in UVB damaged HS68 cells. The increased collagenase activity after UVB damage was significantly recovered by AGR and the tyrosinase activity was significantly reduced. However, the L-DOPA oxidation was not changed. Conclusion : AGR showed the anti-wrinkle effects and whitening effects in vitro. These results suggest that AGR may have potential as an anti-aging ingredient in cosmetic herbs.

Objectives : The purpose of this study was to investigate the effects of Angelicae acutilobae Radix Water Extract (AA) on the production of cytokines in RAW 264.7 cell stimulated with lipopolysaccharide (LPS). Method : RAW 264.7 cells were cotreated with AA (50 and $100{\mu}g/mL$) and lipopolysaccharide (LPS; $1{\mu}g/mL$) for 24 hours. After 24 hours treatment, using bead-based multiplex cytokine assay, concentrations of various cytokines such as interleukin(IL)-6, tumor necrosis factor-alpha(TNF-${\alpha}$) granulocyte colony-stimulating factor(G-CSF), granulocyte macrophage colony-stimulating factor(GM-CSF), and macrophage inflammatory protein(MIP)-$1{\alpha}$ were measured. Result : AA significantly inhibited LPS-induced production of IL-6 and MIP-$1{\alpha}$ from LPS-stimulated RAW 264.7 cells at the concentration of $50{\mu}g/mL$. AA significantly inhibited LPS-induced production of TNF-${\alpha}$ from LPS-stimulated RAW 264.7 cells at the concentration of $100{\mu}g/mL$. AA significantly inhibited LPS-induced production of G-CSF and GM-CSF in RAW 264.7 cells at the concentrations of 50 and $100{\mu}g/mL$. Conclusion : These results suggest that AA has anti-inflammatory effect related with its inhibition of proinflammatory cytokines such as IL-6, TNF-${\alpha}$, G-CSF, GM-CSF, and MIP-$1{\alpha}$ in LPS-induced macrophages.
