본 연구는 근생성 효능을 가진 천연화합물을 발굴하고자 oxypeucedanin hydrate가 근생성과 미토콘드리아에 미치는 영향 및 항암제 유도 미토콘드리아 손상에 대한 완화효과를 C2C12 근원세포와 zebrafish 모델을 통해 각각 확인하였다. 그 결과, oxypeucedanin hydrate는 다핵의 근관세포의 수와 분화말기 표지자인 Myh4의 발현량을 증가시켰고 근육단백질 분해 인자인 MuRF1과 MAFbx의 발현량은 감소시켰다. 또한 미토콘드리아 생합성 조절인자인 Pgc1α, Tfam과 전자전달계 구성인자인 Sdha, Cox1의 발현은 증가시키고, 미토콘드리아 융합인자인 Opa1의 발현 또한 증가시킴과 동시에 미토콘드리아 분열을 표지하는 Drp1의 발현은 감소시켰다. 한편 zebrafish 모델을 통해 항암제 유도 미토콘드리아 손상에 대한 개선효과를 확인한 결과, oxypeucedanin hydrate는 항암제에 의해 유도된 미토콘드리아 손상을 완화시켰다. 이상의 결과들은 oxypeucedanin hydrate가 미토콘드리아 기능 증진을 매개로 근원세포 분화 촉진 및 근육 단백질 분해 저하 효과를 나타냄을 시사한다. 따라서 본 연구를 통해 oxypeucedanin hydrate가 근생성 효과를 나타낼 수 있는 잠재적인 유효소재로서의 가능성을 제시하였다.

Five furanocoumarins including a new one were isolated from the root of Angelica dahurica by repeated silica gel column chromatography. Their chemical structures were determined to be isoimperatorin (1), oxypeucedanin hydrate-3"-butyl ether (2), imperatorin (3), knidilin (4), and oxypeucedanin hydrate (5). This represents the first study in which the compound 2 has been isolated and identified, The long-range coupling ($^{5}J$) in the $^1H$-NMR spectrum observed in the linear furanocoumarin skeleton was also investigated in detail.

Ten coumarins were isolated from the root of Angelica dahurica by repeated silica gel column chromatography. Their chemical structures were elucidated on the basic of physicochemical and spectroscopic data. Among them, oxypeucedanin hydrate acetonide (7) was isolated for the first time from this plant. Cytotoxicity of coumarins isolated were determined in vitro against L1210, HL-60, K562, and B16F10 tumor cell lines by MTT method. Pangelin (5) and oxypeucedanin hydrate acetonide (7) showed a potent cytotoxic activity with the $IC_{50}$ values of 8.6 to 14.6 ${\mu}g$ /mL against four kinds of tumor cell lines. Other compounds showed the moderate cytotoxic activity or no activity against the tumor cell lines.

Four furocoumarins and two dihydrofuranocoumarin glycosides have been isolated from the benzene-soluble and butanol-soluble portions of the roots of Ostericum koreanum Kitagawa, respectively. Four furocoumarins have been determined as imperatorin, isoimperatorin, oxypeucedanin and oxypeucedanin hydrate, and two dihydrofuranocoumarin glycosides determined as marmesinin and $4'-O-{\beta}-D-glucopyranosyl-3'-hydroxymarmesin$ on the basis of spectral data and physico-chemical evidence.

To investigate biological active constituents from natural products, we have studied the roots of Angelica koreana Max. (Umbelliferae). Fifteen compounds were isolated from the MeOH extract by column chromatography on a silica gel. The compounds were identified as isoimperatorin, oxypeucedanin, oxypeucedanin hydrate, osthol, nodakenin, 2-hydroxy-4-methylacetophenone, cimifugin, falcarindiol, heraclenin, pabulenol, umbelliferone, demethylsuberosin, hamaudol, sec-O-glucosylhamaudol, and prim-O-glucosylcimifugin, respectivelv, by spectroscopic means. Among these, the latter eight compounds were isolated for the first time form this plant.

백지는 산형과(Umbelliferae)에 속하는 구릿대(Angelica dahurica)의 뿌리를 건조한 것으로, 다양한 약리작용을 하는 것으로 알려져 예로부터 한약재로 사용되어 왔다. 백지의 대표적인 활성 성분인 coumarin을 포함하여 다양한 성분이 알려져 있으며, 최근 백지의 다양한 생리활성이 보고되고 있다. 본 연구는 백지를 건강기능식품의 기능성 원료로 활용하고자, 백지의 지표성분 설정 및 이에 대한 UPLC 분석법을 확립하여 분석법 유효성 검증을 실시하였다. 백지의 지표성분으로는 oxypeucedanin hydrate, byakangelicol, oxypeucedanin, imperatoin, phellopterin, isoimperatorin의6종을 설정하였다. 분석법 유효성 검증은 특이성, 직선성, 검출한계, 정량한계, 정확성, 정밀성 등의 항목을 이용하여 확인하였다. 본 시험법에서 지표성분 6종은 서로 간섭없이 분리되어 특이성을 확인하였고, 결정계수의 값도 0.999 이상으로 나타나 높은 직선성을 나타내었다. 분석법 유효성 검증 결과, 지표 성분 6종의 RSD는 5% 이하로 나타났으며 90-110%의 범위의 회수율을 나타내 높은 정확성과 정밀성이 있는 것을 확인할 수있었다. 이러한 결과는 UPLC를 이용한 백지의 지표성분 분석법이, 새롭게 제시한 6종에 대해 적합한 동시분석 분석법임을 나타낸다. 따라서, 본 연구를 통하여 확립된 백지의 지표성분 분석법이 향후 백지(구릿대)의 건강기능식품 기능성 원료 개발을 위한 기초자료로 활용될 것으로 기대된다.

Four coumarins (1-4) and one polyacetylene (5) were isolated from the roots of Anglica purpuraefolia Chung (Umbelliferae) through repeated column chromatography. Four coumarins, isoscopoletin (1), oxypeucedanin hydrate (2), arnottinin (3) and isokhellactone (4), and a polyacetylene, (+)-9(Z), 17-octadecadience-12,14-diyne-1,11,16-triol (5), were identified by spectroscopic analysis including two dimensional NMR and mass. These compounds were examined for their anti-complement activity against the classical pathway of the complement system. However, compounds 1-5 were inactive in this assay system.

Five coumarins, isoimperatorin (1), pabulenol (2), isooxypeucedanin (3), oxypeucedanin hydrate (4) and osthol (5) were isolated from the MeOH extract of Angelica genuflexa in the course of searching for anti-platelet and anti-coagulant components from plants. Pabulenol (2) was isolated from A. genuflexa for the first time. The five compounds isolated from A. genuflexa, together with decursinol angelate (6), decursin (7) and nodakenin (8) from A. gigas were evaluated for their effects on platelet aggregation and blood coagulation. Compounds 2, 5, 6 and 7 were observed to be either equally effective or 2∼4 times more inhibitory than ASA in both arachidonic acid and U46619 ($TXA_2$ mimetic) induced platelet aggregations.

Angelica genuflexa (Umbelliferae) is a perennial herbaceous plant which has also been variously reported as A. koreana and Ostericum koreanum. The MeOH extract was reported to have strong anti-thrombotic potential in the acute thrombosis model. In our preliminary testing, the MeOH extract and one of the solvent fractions (90% MeOH fr.) were observed to have both platelet anti-aggregating and anti-coagulant effects. Five coumarins, isoimperatorin (1), pabulenol (2), isooxypeucedanin (3), oxypeucedanin hydrate (4) and osthol (5) were isolated from the MeOH extract of Angelica genuflexa in the course of searching for anti-platelet and anti-coagulant components.
