  • The total ethanol extract of Angelica koreana radix (UmbeUiferae) showed potent inhibitory effect on tumor necrosis factors (TNF-${\alpha}$) production from LPS-stimulated RAW 264.7 cells in screening studies on 118 Korean medicinal plants. The activity-guided fractionation of the total ethanol extract resulted in the isolation of 4 compounds, including active substances. The chemical structures of the compounds isolated were established by chemical and spectrometric analyses as imperatorin, isoimperatorin, osthol and oxypeucedanin. Among them, osthol, oxypeucedariin and isoimperatorin showed significant inhibitory activities on TNF-${\alpha}$ production as 54.3${\pm}$2.1%, 33.6${\pm}$1.0% and 17.7${\pm}$3.0%, respectively, at 12.5${\mu}$g/ml.

  • Essential oil of the root of Angelica koreana Max. (Umbelliferae) was investigated. Essential oil was obtained from the dried roots by steam distillation and fractionated by column chromatography. Each isolate or fraction was identified by GC, GC-MS and spectral analysis. It was found to contain nine monoterpenes such as ${\alpha}-pinene$(7.0%), camphene, ${\beta}-pinene$, myrcene, ${\alpha}-phellandrene$, ${\Delta}-3-carene$, p-cymene, limonene(2.8%), terpinolene and also found to contain m-cresol(11.6%), citronellol, citral b, methylcinnamate, eudesmol and osthol. 2-Hydroxy-5-methylacetophenone and twelve compounds were tentatively identified.

  • 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.

  • The herb of Artemisia capillaris in Chinese medicine is used to treat hepatic diseases. In this research, qualitative analysis was performed using a UPLC/Q-TOF-ESI-MS/MS method for rapid identification of phenolic substances from A. capillaris: three caffeoylquinic acids (chlorogenic acid, 3,5-di-O-caffeoylquinic acid, and 4,5-di-O-caffeoylquinic acid), three flavonoids (hyperoside, isorhamnetin 3-O-robinobioside and quercetin) and three prenylated coumarins (6,8-diprenylumbelliferone, cedrelopsin and osthol) were identified. The three prenylated coumarins have not been reported from A. capillaris.

  • 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.

  • 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.

  • Thirteen compounds were isolated from the roots of Angelica genuflexa through repeated silica gel column chromatography. Nine coumarins, isoimperatorin (1), osthol (2), demethylsuberosin (3), oxypeucedanin (4), heraclenin (5), pabulenol (7), umbelliferone (8), oxypeucedanin hydrate (9) and marmesinin (11), and four chromones, hamaudol (6), cimifugin (10), sec-O-glucosylhamaudol (12) and prim-O-glucosylcimifugin (13), were identified by physicochemical and spectroscopic analysis. Among these, compounds 3, 5, 6, 8, 12, and 13 were isolated for the first time from the roots of Angelica genuflexa. These coumarins and chromones were examined for their anticomplement activity. Demethylsuberosin (3) showed a weak anticomplement activity with an $IC_{50}$ value of $390\;{\mu}M$.

  • The purpose of this study was to identify the applicability, main compounds, and target genes of Cnidii Fructus (CF) in the treatment of gastritis using network pharmacology. The compounds in CF were searched in Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and a database of medicinal materials and chemical compounds in Northeast Asian traditional medicine (TM-MC). The target gene information of the compounds was collected from pubchem and cross-compared with the gastritis-related target gene information collected from Genecard to derive the target genes. Gene ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis were performed on the derived target genes. Afterwards, network analysis between compounds and disease target genes was performed using cytoscape. We identified 121 active compounds and 139 target genes associated with gastritis. Pathways derived from the GO biological process and KEGG pathway DB primarily focus on target genes related to inflammation (IL-6, IL-8, TNF production, NF-κB transcription factor activity, and NF-κB signaling pathway) and cell death (PI3K-Akt, FoxO). Major targets for CF treatment of gastritis include TP53, TNF, BCL2, EGFR, NFKB1, ABCB1, PPARG, PTGS2, IL6, IL1B, and SOD1, along with major compounds such as coumarin, osthol, hexadecanoic acid, oleic acid, linoleic acid, and stigmasterol. This study provided CF's applicability for gastritis, related compounds, and target information. Evaluating CF's effectiveness in a preclinical gastritis model suggests its potential use in clinical practice for digestive system diseases.
