  • In order to confirm the antimutagenicity of ginseng extracts, mutagenicity of ginseng and several medicinal herbs of which extracts were used as drinks, was examined through the method of Ames test. The obtained results were as follows. 1. Strong mutagenicities for Salmonella tyhimurium TA98, TA100, TA1535 were observed in all sample herbs Paenonia aalbiflora, Rehmannia glutinosa, Astragalus membranaceus, Angelica acutiloba, Cnidium officinale, Laurus nobilis and Panax ginseng without S-9 mix metabolic activation. 2. In the case of S-9 mix metabolic activation, even in a low concentraction, the extracts of Angelica autilobu, Cnidium officinale and Paenonla albtilora showed also a high mutagenicities for the strain TA98 and TA1535. 3. Even in high concentration of ginseng extracts, mutagenicity was almost neglectable through the metabolic activation of S-9 mix, compared with other extracts of medicinal herbs.

  • This paper is the fifth report about the fungal diseases of economic resource plants observed newly in Korea. It contains short descriptions on symptoms, occurrence conditions, pathogens, and some phytopathological notes for each of 10 fungal plant diseases. They are identified as leaf spot of Adenophora triphylla var. japonica by Septoria lengyelii, leaf spot of Calystegia soldanella by S. convolvuli, leaf spot of Campanula punctata by S. campanulae, leaf spot of Codonopsis lanceolata by S. codonopsidis, leaf spot of Geum japonicum by s. gei, black spot of Oenanthe javanica by s. oenanthes, leaf spot of Oenothera odorata by S. oenotherae, angular leaf spot of Rehmannia glutinosa by S. digitalis, brown spot of Rubus crataegifolius by s. rubi, and leaf spot of Viola verecunda by S. violae-palustris, respectively.

  • The contents of index components in 5 medicinal crops cultivated at different heights in Andong area. The contents of allantoin in Dioscorea batatas Decne and catalpol in Rehmannia glutinosa Liboschitz were not different by cultivation heights (100 ~ 200m). But the contents of index components in Astragalus membranaceus and Angelica acutiloba Kitagawa were higher in samples cultivated at elevated heights. At 700 m of heights, the contents of formononetin and astragaloside I in Astragalus membranaceus were 1.20 and $201.2{\mu}g/g$, respectively. The contents of decursin and nodakenin in Angelica acutiloba Kitagawa were 68.3 and 4.20 mg/g, respectively. Thus Astragalus membranaceus and Angelica acutiloba Kitagawa are recommended to be cultivated in higher altitude.

  • The aim of this study is to explore the potent phosphodiesterase 4 and 7 inhibitor from various herbal medicines for atopy treatment. In this study, 51 kinds of each herbal medicine, which were extracted with ethanol, was carried out the screening of PDE 4 and 7 inhibition using enzyme inhibitory assay. Of these, 8 species of herbal medicines, Rubus coreanus, Duchesnea chrysantha, Alisma orientale, Rehmannia glutinosa, Angelica dahurica, Thuja orientalis, Astragalus membranaceus and Perilla frutescens were screened as potential inhibitor against PDE 4 and 7. Among 8 species, Duchesnea chrysantha showed poteinial anti-atopic effect on DNCB-induced atopic model. Duchesnea chrysantha extract decreased serum IgE and histamine release significantly.
