Isoimperatorin and Oxypeucedanin isolated from root of Angelica Koreana Max. (Umbelliferae) that is used as "Kang-Whal" a botanical drug, in Korea, Show following general pharmacologic activities. The treatment with Oxypeucedanin on the exercised duodenum of the rabbit increased the motility of it while isoimperatorin shows little effects. But on the exercised heart of the frogs, both components depressed its contractility. Whereas Oxypeucedanin depressed both blood pressure of the carotied artery and respiration of the rabbit, Isoimperatorin tends to increase blood pressure, respiration and the tonus of the muscle of the earth worm. Oxypeucedanin did not affect the tonus of the muscles of the earth worm, but depressed the uterus contraction of the rabbit, which was, on the contrary, increased by Isoimperatorin.

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.

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.

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.

From the ethereal extract of the roots of Angelica koreana Max. (Umbelliferae) two furanocoumarins such as isooxypeucedanin and oxypeucedanin methanolate were newly isolated together with isoimperatorin, osthol, imperatorin, bergapten, oxypeucedanin and ${\beta}-sitosterol$.

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.

In this study, we analyzed and quantified the amounts of bioactive phenolic constituents, xanthotoxin (1), oxypeucedanin (2), and imperatorin (3) in each part of the root of Angelica dahurica by HPLC, which validated by ICH guide lines comparing the linearity, intra day precision, inter-day precision. As a result, the amount of imperatorin 2.96% in the rootlet was two fold higher than that of the main root 1.32%. On the other hand, the amounts of xanthotoxin and oxypeucedanin in the rootlet showed similar to those of main root. In addition, the cortex of root is more plentiful of three consitituents (0.66%, 0.53%, and 1.85%) than those of xylem (0.29%, 0.05%, and 0.07%). These results show that the rootlet and cortex contain a large amount of bioactive phenolic constituent including xanthotoxin, oxypeucedanin, and imperatorin than other parts of the root.

Angelicae Koreanae Radix has been used for controlling inflammatory respiratory diseases in folk medicine and their components, imperatorin, marmesinin and oxypeucedanin were reported to have diverse biological effects. In this study, we investigated whether imperatorin, marmesinin and oxypeucedanin affect adenosine triphosphate(ATP)-induced mucin secretion from cultured airway epithelial cells. Confluent primary hamster tracheal surface epithelial(HTSE) cells were metabolically radiolabeled using $^3H$-glucosamine for 24 h and chased for 30 min in the presence of varying concentrations of each agent to assess the effects on $^3H$-mucin secretion. The results were as follows: 1) imperatorin significantly inhibited ATP-induced mucin secretion; 2) However, marmesinin and oxypeucedanin did not affect ATP-induced mucin secretion, significantly. We conclude that imperatorin might inhibit ATP-induced mucin secretion by directly acting on airway mucin-secreting cells. Therefore, imperatorin should further be investigated for the possible use as mucoregulators in the treatment of inflammatory airway diseases.

The medicinal constituents contained in Korean and Chinese Angelicae dahuricae Radix were compared by confirming their qualities. From the extracts of Angelicae dahuricae Radix, oxypeucedanin, imperatorin, and alloisoimperatorin etc. furanocoumarin derivatives were identified by GC/MS analysis. Through GC/FID analysis, the furanocoumarin derivatives content of Baizi cultivated in Korea was more than that cultivated in China, except for one cultivated at Ankuk province, and so confirmed to possess, on the whole, good quality medicinal constituents by content, as compared with the ones cultivated in China.
