  • 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 result were achived from 29 kinds of the medical literature of many generation is like this. 1. Oriental medical expressions of Xerophthalmia are "Baksab(白澁)", "Kunsabhonhwa(乾澁昏花)", "Sinsoojanggo(神水將枯)", "Donginkunkyul(瞳人乾缺)", "Taljung(奪精)", etc. "Baksab(白澁)" is very close to Xerophthalmia. 2. The cause of Xerophthalmia is Wind, Wind-heat Pathogen, Damp-heat of spleen and lung, DefIciency of body fluid, Yin-deficiency of liver and kidney, Liver deficiency syndrome, Deficiency of blood, Fire, Fire of deficiency type, Liver heat, etc. 3. In the frequency of prescription used Xerophthalmia are "Sangbakpi-Tang(桑白皮湯)", "Eunkyosan(銀翹散)", etc as Excess type, "Kikookjihwang-Tang(杞菊地黃湯)", "Samooloja hwan(四物五子丸)", etc as Deficiency type. 4. In the frequency of medical herbs of Xerophthalmia use much Rehmannia root nourishing Yin and clearing away heat and Divaricate Saposhnikovia root(expelling pathogenic wind.

  • 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.

  • We have tested 101 species traditional medicinal plants on Acetylcholinester ase inhibition. Among them. Caesalpina sappan. Cnidium offcinale, Coptis japonica, Ephedra sinica, Eribotrya japonica, Gardenia jasminoides, Liriope platyphylla, Lonicera japonica, Paeonia suffruticosa, Phyllostachys nigra, Polygonum multiflorum, Prunella vulgaris, Rheum undulatum, Salvia miltiorrhiza and Uncaria rhynchophylla showed strong inhibition potency over 88%. In addition, Aconitum carmichaeli, Caesalphina sappan, Cinnamomun japonica, Citrus unshiu, Hordeum vulgare, Glycine max and Rehmannia glutinosa showed relatively good inhibition potency over 80%.
