Prolyl endopeptidase (PEP, EC 3.4.21.26), also referred to as prolyl oligopeptidase, has been suggested to participate in learning and memory processes by cleaving peptide bonds on carboxyl side of prolyl residue within neuropeptides of less than 30 amino acids, and is abundant in brains of amnestic patients. Therefore, compounds possessing PEP inhibitory activity can be good candidate of drug against memory loss. Upon examination for PEP inhibition from traditional medicinal plants having tonic, stimulating, and anti-amnestic effects, Corni Fructus (Cornus officinallis) showed significant PEP inhibition. Ursolic and oleanolic acids, components of Corni Fructus, inhibited PEP with $IC_{50}$ values of $17.2\;{\pm}\;0.5$ and $22.5\;{\pm}\;0.7\;{\mu}M$, respectively.

Natural products in Chonnam, Korea were screened via anti-angiogenesis experiments, and 1 candidate product was identified, Corni fructus, which exerted dose-dependent inhibitory effects against angiogenesis, adipogenesis, and cell adhesion. C. fructus extract (CFE) exhibits an angiogenesis inhibitory effect superior to that of the EGCG from green tea leaves. The expression level of angiogenesis and adipogenesis-related signal molecules in the western blotting was reduced by increasing the amount of added CFE. Moreover, a diet supplemented with CFE was deemed more effective in inducing weight loss in LB mice than a representative synthetic diet drug, orlistat, which incidently caused the side effect of denuding the mice of their hair. These results indicate that C. fructus may prove to be a useful anti-adipogenic compound, and these in vitro results may be reflected later under in vivo conditions.

Two Fructus Jujubae & three Rhizoma Zingiberis Rencns are usually used in parts of prescriptions in oriental medicine. In "Dongeuibogam", those are prescribed as drugs. However, those are not exactly same with original books, which "Dongeuibogam" had quoted. In original books, those are sometimes mentioned just as 'Fructus Jujubae & Rhizoma Zingiberis' or different amount of them. Therefore, authors try to compare with "Dongeuibogam" and its original books to find out the reason of discordance. As a result, we could conclude that Two jujubes & three pieces of ginger are more commonly prescribed than original books and are fixed to use more conveniently and to give standard for doctor.

Zanthoxyli Fructus has been used in traditional medicine for the treatment of analgesic, gastric disorder, rheumatism etc. In order to evaluate the quality of Zanthoxyli Fructus, the method of isolation and quantitative determination of xanthoxylin as a standard compound has been developed. The HPLC method, using the mobile phase of acetonitrile-water (4:6), showed that the amount of xanthoxylin wεre in the rangε of 0.01 to 2.67%.

Objectives : We studied on anti-allergic effects of Arctii Fructus Herbal Acupuncture(AFHA) and Arctii Fructus Herbal Acupuncture Solution(AF). Methods : In vivo, Animals were herbal-acupunctured AFHA at both ST36 three times for 5 days. Then, we investigated compound 48/80-induced active systemic anaphylaxis(ASA) using ICR mice and anti-DNP IgE-induced passive cutaneous anaphylaxis(PCA) using Sprague Dawley rat. In vitro, we measured cell viability, b-hexosaminidase, IL-4 and TNF-a release from RBL-2H3 cells after treatment of AF of various concentrations. Results : In vivo, AFHA pretreatments at both ST36 inhibited compound 48/80-induced ASA. PCA was inhibited by AFHA pretreatments at both ST36. In vitro, AF treatments were not affect on cell viability and inhibited b-hexosaminidase, IL-4 and TNF-a release. Conclusions : These results suggest that AFHA and AF may be beneficial in the inhibition of allergic inflammatory response.

Meliae toosendan Fructus is the fruit of Melia toosendan $S_{IEB}$. et $Z_{UCC}$. (Meliaceae), which is written in oriental terminology as clearing heat and drying dampness, and also explained using liver, stomach and small intestine for channels entered. Among the five fractions prepared from methanol whole extractive of the herb, the chloroform fraction which suggests the presence of triterpenoid, flavonoid and alkaloid stimulated the activities of drug metabolizing enzymes and bile secretion and lowered the serum transaminase activities of liver damaged by carbon tetrachloride.

The term keratosis covers a variety of growths such as warts and pressure-induced callosities. Warts develop in the absence of pressure, and often clear up again after a certain period, usually without treatment. Clavi can develop as a result of wearing poorly fitting shoes, but also deformed toes or other anatomical deformities affecting the foot. The resulting non-anatomical stressing leads to the formation of pressure callosities and even to pressure sores. It confronts hereupon, it searched the cure against the clavus with fructus mume(烏梅) and it arranged. The possibility of getting the result regarding the clavus treatment with fructus mume(烏梅) from the oriental medicine it was.

Abstract - The Evodiae Fructus is known for containing a number of indolquinazoline and quinoline type alkaloids. Evodiamine, evocarpine and rutaecarpine are the major constituents of alkaloids. These alkaloids were isolated and determined by forming complex compounds from Evodiae Fructus in O-Su-You-Tang. For the determination of these alkaloids, a new spectrophotometric method was developed with a simple and selective sample clean-up using thiocyanatocobaltate[II] compIεx compound ion. The absorbance of alkaloidal complex compounds in 1,2-dichloroethane solution was measured at 625 nm. The method proved to be rapid, simple and reliable for the isolation and the determination of the alkaloids in O-Su-You-Tang.

To screen antioxidative and whitening effects of some medicinal plants, 70% ethanol extracts were tested for their electron donating abilities to DPPH ( ${\alpha}$, ${\alpha}$-diphenyl- ${\beta}$-picrylhydrazyl) and inhibitory activities against lipid peroxidation, and tyrosinase inhibition in vitro. The electron donating activities of 70% ethanol extracts at the concentration of 100 $\mu\textrm{g}$/ml were in the order of Forsythiae fructus > Polyporaceae > Glycyrrhizae radix > Schizandrae fructus > Ramulus mori > Carthami semen. The order was Forsythiae fructus > Carthami semen > Schizandrae fructus > Polyporaceae > Glycyrrhizae radix when tested at 10 $\mu\textrm{g}$/ml, indicating that the activities depend on the concentration. The electron donating activities of Forsythiae fructus and Carthami semen at the concentration of 1 $\mu\textrm{g}$/ml were 37% and 31% respectively. Lipid peroxidation inhibitory activities were in the order of Artemisia messerschimidtiana > Glycyrrhizae uadix > Rehmaniae radix > Ramulus mori. Tyrosinase inhibitory activities were in the order of Ramulus mori > Artemisia messerschimidtiana > Oyster mushroom. The results suggest that Forsythiae fructus, Artemisia messerschimidtiana and Ramulus mori could be used as materials for anti-skin aging functional cosmetics.
