  • A cytotoxic sesquiterpene against L1210 and Hl-60 cells was isolated from Angelicae Koreanae Radix (bulk-kang-hwal). The component was identified as bisabolangelone by means of chemical and physical methods. The $ED_{50}$ values of it were $1.20{\;}\mu\textrm{g}/ml$ against L1210 cells and $2.30{\;}\mu\textrm{g}/ml$ against HL-60 cells. Bisabolangelone was found in bulk-kang-hwal but not in kang-hwal.

  • In order to estimate accurate quality of crude drugs in which pest was found during the storage, damaged 15 items were collected on current markets. We identified insect name by investigation of insect morphology, bug cluster, and morphology of damaged crude drugs. Three kind of pests were identified in the above 15 items as follows: A: Pyralis sp. (Pyralidae) was observed in damaged Platycodi Radix. B: Anthreus verbasci (Anobiidae) was found out in damaged Angelicae gigantis Radix, and Dioscoreae Rhizoma. C: Stegobium pamceum (Anobiidae) was discovered in the 12 crude drugs as follows: Puerariae Radix, Angelicae koreanae Radix, Angehcae tenuissimae Radix, Codonopsis Radix, Ledebouriellae Radix, Ginseng Radix alba, Angelicae dahuricae Radix, Belamcandae Rhizoma, Paeoniae Radix, Cnidii Rhizoma, Alismatis Rhizoma, and Fritillariae Bulbus.

  • The methanol extracts were prepared from 46 oriental medicines currently used for stroke treatment, and the effects were assessed on the excitotoxic neuronal cell death induced by L-glutamate(Glu) in primary cultured rat cortical neurons. The extracts from Angelicae gigantis Radix, Manitis Squama, Acori graminei Rhizoma, Uncariae Ramulus et Uncus, Alpiniae Fructus, Paeoniae Radix, and Cnidii Rhizoma inhibited the Glu-induced neurotoxicity with the IC$_50$ values of 95.2, 218.6, 263.3, 295.1, 297.9, 310.1, and 446.7 $\mu$g/ m$\ell$, respectively. The extracts from Arisaematis Rhizoma, Loranthi Ramulus, Anemarrhenae Rhizoma, Carthami Flos, Clematidis Radix, Bambusae Concretio Silicea, and Angelicae koreanae Radix also exhibited significant inhibition of the toxicity. In contrast, the extracts from Aconiti Tuber Araliae cordatae Radix, Curcumae Rhizoma, Leonuri Herba, Polygalae Radix, Salviae Radix, and Siegesbeckiae Herba increased the Glu-induced toxicity at the concentrations of 500 and 1000 $\mu$g/m$\ell$. Rest of the extracts evaluated in the present study showed minor or negligible inhibition. liken together the oriental medicines including Angelicae gigantis Radix, Muitis Squama, Acori graminei Rhizoma, Uncariae Ramulus et Uncus, and Alpiniae Fructus appear to exert pharmacological effects through the inhibition of excitotoxic neuronal cell death. Further studies are in progress to characterize active principles in these extracts.

  • A mouse whole animal bioassay was employed to screen for potential mutagenicity of ethanol/water extracts of 16 Chinese herbal drugs that are commonly prescribed in Korea. Specific cytogenetic toxicity was measrured by recording evidence of clastogenesis toxicity was measured by recording evidence of clastogenesis via the mouse bone marrow micronucleus test. Male ICR mice administered ethanol extract of Pinelliae tuber (Pinellia eternata Breitenbach, ARACEAE, 양복) and ddY female mice administered extract of Angelica Koreanae radix(Angelica Koreana Maximowicz, UMBELLIFERAE, ) (both by oral administration, at a dose of 600 mg/kg), in a short-term dosing schedule, demonstrated significant increase in micronucleated polychromatophilic erythrocytes, indicating the increase of clastogenicity.

  • 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.

  • 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.
