To clarify the botanical origins of oriental medicines which have been argued or confused for plant origins, species of original plants were investigated through the textural research for oriental medicines and the comparison of Chinese, Korean, Japanese and North Korean Pharmacopoeia. Twenty oriental medicines were studied; Angelicae Gigantis Radix, Rhei Rhizoma, Atractylodis Rhizoma Alba, Aconiti Lateralis Radix Preparata, Acanthopanacis Cortex, Osterici Radix, Cnidii Rhizoma, Saposhnikovae Radix, Magnoliae Cortex, Paeoniae Radix, Liriopis Tuber, Zanthoxyli Fructus, Achyranthis Radix, Sinomeni Caulis et Rhizoma, Polygonati Rhizoma, Cinnamomi Cortex, Visci Herba et Loranthi Ramulus, Fritillariae Thunbergii Bulbus, Pogostemonis Herba, and Curcumae Longae Radix.

Methanol and/or boiling water extraction of 201 natural products and subsequent MTT assay using MT-4 cell line was carried out to screen the anti-HIV-1 activity. Among 97 methanol extracts, 7 extracts from Chrysanthemi Indicium Flos, Magnoliae Cortex, Machili Cortex, Reynoutriae Rhizoma, Lithospermi Radix, Agastachis Herba, and Chaenomelis Fructus showed anti-HIV-1 activity and their SI value were 2.25 to 5.77. In addition, among 119 boiling water extracts, 10 extracts from Lonicerae Caulis et Foloium, Elsholtziae Herba, Leonuri Herba, Portulacae Herba, Schizonepetae Herba, Curcumae Rhizoma, Amomi Cardamomi Fructus, Cirsii Radix et Herba, Carpesii Herba, and Siegesbeckiae Herba showed anti-HIV-1 activity and their SI value were 1.30 to 7.64. Methanol extracts of above seven natural products were fractionated and the anti-HIV-1 activity of each fraction was examined. Extraction was carried out with hexane, chloroform, butanol, and water to trace active anti-HIV-1 componets. As a result, the water fraction of Magnoliae Cortex, Machili Cortex, Reynoutriae Rhizoma, Agastachis Herba, Chaenomelis Fructus and the butanol fraction of Chrysanthemi Indicium Flos, Reynoutriae Rhizoma showed anti-HIV-1 activity and their SI value were 1.40 to 8.02. We could reach a conclusion that studies to trace the anti-HIV-1 active component of each natural products in further fractionation and to identify its structure by Infrared spectroscopy, NMR spectroscopy and gel permeation chromatography were needed.

The water extracts of ten crude drugs were tested for the spasmolytic and anti-peptic ulcer activities on rat ileum smooth muscle contraction and aspirin-induced acute hemorrhag ic erosive gastritis respectively. The water extract of Aurantii immaturi pericarpium(AIP)($IC_{50}=1.5{\times}1O^{-2}$g/l), Aurantii nobilis pericarpium(ANP)($IC_{50}=2.5{\times}1O^{-2}$g/l), Cyperi rhizoma(CR)($IC_{50}=3.3{\times}1O^{-2}$g/l). Linderae radix(LR) ($IC_{50}=6.8{\times}1O^{-2}$), Aurantii fructus immaturus(AFI)($IC_{50}=11.8{\times}1O^{-2}$), Saussureae radix(SR)($IC_{50}=13.2{\times}1O^{-2}$g/l) and Ponciri fructus(PF)($IC_{50}=23.3{\times}1O^{-2}$g/l) showed inhibitory activity on the isometric contraction of rat ileum smooth muscle induced by electrical stimulation in a concentration-dependent manner, whereas the water extracts of Arecae pericarpium(AP), Agastachis herba(AH) and Magnoliae cortex(MC) potentiated the isometric contraction. In the aspirin-induced acute gastritis, the water extracts of MC, AP and CR reduced significantly the gastric juice secretion, gastric juice acidity and pepsin activity. They also showed protective activity of gastric mucosal layer from erosion and petichial hemorrhage in gross and histological examination.

To certify the protective effect of herbal medicine against oxygen free radical-induced myocardiotoxicity, cytotoxicity was measured using LDH activity and TBARS assay in the presence of Jisilhaebaekgyejitang(JHGT) extracts or single constituents of this prescription, In the present study, xanthine oxidase/hypoxanthine (XO/HX) resulted in a cell damage such as increases in LDH activity in culture medium and lipid peroxidation in cultured myocardial cells. In the effect of JHGT extract and its single constituents, which are Fructus Ponciri Seu Aurantii Immaturus (FPSAI), Cortex Magnoliae Officinalis (CMO), Bulbus Allii Macrostemi (BAM), Ramulus Cinnamomi (RC) and Fructus Trichosanthis (FT), they showed the prevention from the XO/HX-induced cardiotoxicity by the decrease of LDH activity and lipid peroxidation. From these results, they show that XO/HX is cardiotoxic in cultured myocardial cells derived from neonatal rat, and it suggests that JHGT, FPSAI, PT, CMO, BAM, RC and FT extracts are positively effective in the blocking in XO/HX-induced cardiotoxicity.

It has been known that Magnolia officinalis, Magnolia and Machilus Barks are reputed to be effective in 'Hagi', 'Sanman' and to be analgesic but there was differences of efficacy of these crude drugs against the kinds and habitates. For this reason, this study was conducted to compare the acute toxicities, analgesic effects and motilities of isolated intestine. This results obtained in this work were summarized as follow: 1. In the test of acute toxicies, Machilus bark was found to be more toxic than the others. 2. Both these was found to have analgesic effect. 3. In the effects against the motility of isolated intestine, Magnolia officinalis and Magnolia barks were found to be relaxant, Machilus bark was found to be contractive. From these results, Magnolia officinalis and Magnolia barks might have analgesic effect and relaxant effect of intestine.

Infection with Helicobacter (H.) pylori is strongly associated with duodenal and gastric ulcers. Substantial epidemiological data has revealed that high rates of H. pylori infection might be related to high rates of gastric cancer. In this study, a medicinal herbal extracts were examined and screened for anti-H. pylori activity. Seventy percent ethanol was used for herbal extraction. For anti-H. pylori activity study, the inhibitory zone tests with 74 herbal compounds were conducted. As the results, thirteen compounds including Cinnamomi Cortex, Magnoliae Cortex and Meliae Fructus were revealed strong anti-H. pylori activities.
