  • Persimmon has been considered to have a therapeutic value diseases in Korea, Dried, persimmon was applied to a wounded part for an anti-inflammatory and analgesic activities, Anti-coagulating activity has been detected in persimmon by a thrombin-induced clotting assay using human plasma. The anti-coagulating activity was detectible in stem, pulp, core, leaf, and seed of persimmon The stem part of persimmon contains maximal anti-coagulating activity after-size-fractionation. Both of an anticoagulant and its denaturating factor were present in persimmon pulp. The concentration of anti-coagulating activity was determined and compared in different harvesting time, species, and available foods. The level of anti-coagulating activity was highest in persimmon(Fuyu)harvested in November. The anti-coagulating activity was decreased significantly in its processed foods. Persimmon could be expected to be effective in prevention of diseases induced by excess coagulation.

  • Sarcodon aspratus (Thelepholaceae), a native mushroom, is distributed in Korea and Japan, and has been widely used in traditional food and fork medicines. To confirm the biological activities of Sarcodon aspratus, the liver protecting activity, anti-clotting activity, and anti-complementary activity of the water extract, EtOH extract, and the water soluble proteoglycan part of S. aspratus were investigated. The EtOH, and water extract of S. aspratus decreased the GOT and GPT releases induced by $CCl_4$ in a dose-dependant manner. On the other hand, the water soluble proteoglycan part of S. aspratus showed weak inhibitory activity. In addition, the EtOH and water extract of S. aspratus prevented $CCl_4-induced$ hepatotoxicity, as described by a liver histopathologic study. To confirm the anti-clotting activity, the APTT and PT assay were carried out. As a result, only the crude proteoglycan part of S. aspratus showed the anti-coagulating activity, and this result might be due to the inhibition of intrinsic clotting system. Also, the crude proteoglycan part of S. aspratus showed the anti-complementary activity, and the $IC_{50}$ value was $50\;{\mu}l/ml$.

  • The leaf extract of Ligularia stenocephala showed the highest anti-platelet aggregating activity in large numbers of edible and herbal plants. The active fraction fractionationed from L. stenocephala extract by using preparative HPLC inhibited the platelet aggregation up to above 80% and its blood coagulating time (PT and APTT) also showed similar effect to aspirin (0.2 ${\mu}g/mL$), known as an anti-thrombus compound. Two antithrombus active compounds were purified and identified as 3,5-dicaffeoylquinic acid and 3,4-dicaffeoylquinic acid, respectively, on the basis of NMR and FAB-MS spectroscopic data. Two active compounds has not only antiplatelet aggregating activity, but also has anticoagulating activity.
