딱지꽃(Potentilla chinensis)은 약초식물의 하나로 항염, 지혈, 해독 그리고 해열 등의 효과가 알려져 있다. 특히 딱지꽃의 뿌리는 약제로써 중요한 가치를 지니고 있다. 그러나 기존에 딱지꽃의 줄기나 잎에 대한 유효성분에 대한 연구가 시도된 반면 딱지꽃의 뿌리의 주요성분을 분석한 사례가 없었다. 따라서 본 연구는 딱지꽃의 뿌리를 다양한 용매별로 추출하고 주요한 물질을 분리정제 하였다. 분리 정제된 물질을 NMR과 mass 분석을 통하여 물질을 동정하였고 그 결과 주요성분이 화합물 (1)임을 확인하였다. 또한, 동정된 물질의 산업적 응용을 위해 딱지꽃 뿌리에서 용매별로 화합물 (1) 추출양을 정량하였다.

Korean folk medicine 'Jin Hae Cho' has been used as a remedy for neuralgia and an invigorating drug after a childbirth in Korea. The botanical origin of the crude drug has been no pharmacognostical confirmation on it. To clarify the botanical origin of 'Jin Hae Cho', studied on the morphological and anatomical characteristics of the roots of Potentilla species growing wild in Korea i.e. Potentilla chinensis Ser., P. cryptotaeniae Maxim., P. dickinsii Fr. et Sav., P. discolor Bunge, P. fragarioides L. var. major Maxim., P. freyniana Bornm., P. kleiniana Wight et Arnott, P. paradoxa Nutt., P. yokusaiana Makino and 'Jin Hae Cho' from Korea on Korean market. As a result, it was made clear that 'Jin Hae Cho' from Korea was derived from the roots of Potentilla chinensis Ser. and Potentilla discolor Bunge.

The methylated compound of ellagic acid was isolated from Potentilla chinensis (Rosaceae). The isolated compound was 3, 3', 4-tri-O-methylellagic acid, [2, 3, 7-trimethoxy-8-hydroxy[1] benzopyrano-[5, 4, 3, cde][1] benzopyran-5, 10-dione], $C_{17}H_{12}O_8$, m.p. $293-295^{\circ}C$. The isolation of trimethylellagic acid was conducted by the column chromatography and the identification of the compound was carried out by the methods of IR, NMR and MS spectroscopy.

천연물을 이용한 산업이 증가됨에 따라 전통약재식물들의 화장품소재로 사용하려는 관심이 높아지고 있다. 다양한 약재식물 중 딱지꽃(Potentilla chinensis) 역시도 다양한 약리 활성이 알려짐에 따라 관심이 높아지고 있다. 그러나 다양한 약리활성을 지닌 반면 딱지꽃(Potentilla chinensis) 을 이용한 산업적 응용은 거의 이루어지지 않고 있다. 본 연구에서는 화장품소재로서의 딱지꽃 뿌리 추출물에 관현 연구를 수행하였다. 그 이유는 딱지꽃의 뿌리 부분이 다른 부분보다 더 많은 약리활성을 지녔다는 보고들이 있었기 때문이다. 딱지꽃 뿌리 추출물을 얻어낸 뒤 항염증, 주름개선, 보습 그리고 미백 효과를 확인함에 따라 딱지꽃 뿌리 추출물을 화장품 소재로 응용가능한지 확인하였다. 그 결과 elastin과 aquaporin-3 증가 효과를 확인할 수 있었고, cyclooxygenase-2, metallopeptidase-1 그리고 melanin 합성 억제효과를 확인할 수 있었다.

In this study, we investigated the anti-inflammation effect of Potentilla chinensis (PC) on Raw264.7 macrophage cells. Ethanol extract of PC decreased the production of nitric oxide (NO) in LPS-stimulated RAW264.7 cells. Ethanol extract was fractioned by n-hexane, chloroform, ethyl acetate, n-butanol, water and each fraction was tested for inhibitory effects on inflammation. Among the sequential solvent fractions, PC chloroform extracts (50, 100, 300, and 500 ${\mu}g/mL$) significantly suppressed LPS-stimulated production of NO. During the entire experimental period, 200 and 300 ${\mu}g/mL$ of PC chloroform extracts had no cytotoxicity. LPS-induced NO and prostaglandin $E_2$ ($PGE_2$) production were inhibited by PC chloroform extracts up to 50% and 90% of these productions, respectively. PC chloroform extracts reduced the expression of iNOS and COX-2 gene. These results suggest that PC chloroform extracts exhibit strong effects of anti-inflammation and can be a potential candidate in the treatment of acute and chronic inflammatory diseases.

The Korean folk medicine 'Jin Hae Cho Ip' has been used as a remedy for neuralgia and as an invigorating drug after a childbirth, etc in Korea. With regard to the botanical origin of 'Jin Hae Cho Ip', several species of Potentilla (Rosaceae) has been refired, but no pharmacognostical study has yet been performed in this regard. To clarify the botanical origin of the 'Jin Hae Cho Ip', the morphological and anatomical characteristics of the leaflets and petioles of Potentilla and Sibbaldia species growing in Korea, such as P. chinensis, P. cryptotaeniae, P. dickinsii, P. discolor, P. fragarioides var. major, P. freyniana, P. kleiniana, P. matsumurae, P. paradoxa, and S. procumbens, were compared. As a result, it was found that 'Jin Hae Cho Ip' was composed of the leaves of P. Chinensis and P. discolor.

Potentilla chinensis Ser. (Rosaceae) has long been used for a remedy of diarrhea and inflammation in Korea. In this study, the anti-inflammatory effects of the Potentillae chinensis Herba water extract (PCX) was investigated in proteinase-activated receptor-2 (PAR2)-mediated rat paw edema. Paw edema was induced by injection of trypsin or trans-cinnamoyl-LIGRLO-$NH_2$ (tc-$NH_2$) into the hind paw of rats. PCX (10, 50, 100 and 200 mg/kg) was orally administered 1 h before the induction of inflammation. At doses of 50, 100 and 200 mg/kg, PCX showed significant inhibition on both change in paw volume and vascular permeability. PCX (100 mg/kg) significantly inhibited PAR2 agonists-induced myeloperoxidase (MPO) activity in paw tissue. These results indicate that PCX has an anti-inflammatory action in PAR2-mediated paw edema.

A method of conserving the vegetation at Mt. Chonggye was established to persue a practical management of the natural ecosystem by the vegetative composition analysis. As a result, the vegetation of surveyed areas was classified into two communities and four subcommunities in Mt. Chonggye. Potentilla fragarioides var. major community, known as the roadside plant community, distributed near trails under heavy human impacts. Potentilla fragarioides var. major community included two subcommunities : Digitaria sanguinalis-Ambrosia artemisiifolia var. elatior subcommunity and Rhus chinensis subcommunities. In these communiyies, there were many naturalized plant species such as Aster pilosus and Artemisia princeps var. orientalis, known as heliophilous plant. Results indicated that the vegetation had been affected by intensive human activities. It is necessary to control the naturalized plant species such as Aster pilosus for conservation of the ecosystem and nature in this area. Quercus mongolica community, a common coppice woodland in central Korea, was mostly distributed around mountain tops and ridges above 529 m altitute. In the valley where the forests well conserved, the Quercus mongolica community contained the Syneilesis aconitifolia-Hemerocallis lilioasphodelus subcommunity. On the other hand, Potentilla dickinsii subcommunity was dominated in dry rocky ridge areas. In these areas, however, the vegetation and forest soil was not properly managed for conservation.

The forest vegetation occurring mainly at the mountain areas in periphery of Seoul were inversigated phyeosociologically. The granitic rocky outcrops are typical physiognomy on the study areas. The greater part of forests was the secondary vegetation to be disturbed by hyman impacts, because of being situated near the metropolis with a highly dense population. Four community types were largely differentiated by species composition. The representitive ones were the Quercus monogolica community and Pinus densiflora-Juniperus schinensis community, which are predominantly gorwing at the slopes above about 100m in altituse and the rocky ridges, respectively. The Betula chinensis-Potentilla dickinsii community at several single-peaks of windswept and the Zelkova serrata-Prunus padus community at stony valley are sporadically growing in a small area.
