Armeniacae Semen not only contains amygdalin, but emulsin also, which is an enzyme that hydrolyzes amygdalin. The extraction yield of amygdalin from Armeniacae Semen was low, due to the presence of emulsin, when extracted with water. When Schizandrae Fructus solution was used as the extractant; however, amygdalin was almost completely extracted, regardless of the cutting size, due to the absence of the influence of emulsin. In addition, when the crude powder or small piece forms were used with Schizandrae Fructus solution, on epimerization of the D-amygdalin into neoamygdalin occurred. D-amygdalin and its conversion product, neoamygdalin, were quantitatively analyzed by reverse-phase, high-performance liquid chromatography (HPLC), with an optimized eluent of 10 mM sodium phosphate buffer (pH 2.3), containing 11.5% acetonitrile. The concentration and detector response were linearly correlated over the range 0.05 to 2 mM. The detection limits for both D-amygdalin and neoamygdalin were approximately $5\;{\mu}M$ for the amount injected.

Morphological characteristics in the anamorphic states were described in three species of powdery mildew fungi, Microsphaera akebiae, M. picrasmae and M. schizandrae, which were parasitic on Akebia quinata, Picrasma quassioides, and Schizandra chinensis, respectively. All species were flexuous in foot-cells of conidiophores, producing conidia singly on conidiophores, devoid of fibrosin bodies in conidia, and producing germ tubes on the end of conidia.

In the course of search for hepatoprotective agents from oriental traditional medicines, one compound was isolated from the MeOH extract of the fruits of Schizandra chinensis, and its structure was determined as gomisin J(1). The evaluation for hepatoprotective activity of isolated compound 1 on drug-induced cytotoxicity was conducted, and compound 1 showed protective effect with an EC$_{50}$value of 86.0 ${\pm}$ 5.3 ${\mu}$M against tacrine-induced cytotoxicity in Hep G2 cells. One of the well-known hepatoprotective agents, silybin, used as a positive control, and the hepatoprotective effect of compound 1 is similar with that of silybin (EC$_{50}$ value = 90.5 ${\pm}$ 9.8 ${\mu}$M).

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.

Objectives : Present study investigated the hepatoprotective effects and the optimal mixing ratio of fermented Schizandrae Fructus Pomace (fSFP) and Hoveniae Semen Cum Fructus (HSCF) extract combination in carbon tetrachloride (CCl₄)-induced acute liver injury mice. Methods : ICR mice were orally administered with 200 mg/kg of fSFP, HSCF and mixtures of fSFP and HSCF [MSH (w:w); 1:1, 1:2, 1:4, 1:6, 2:1, 4:1, 6:1, and 8:1] for 7 consecutive days. Silymarin (100 mg/kg) was administered as a reference drug. 0.5 mL/kg of CCl₄ was injected intraperitoneally to induce acute liver injury. Body weight gain, relative liver weight, serum chemistry, histopathological analysis, and hepatic endogenous antioxidants capacities were observed. Results : All diverse combinations of MSH significantly reduced relative liver weight increase by CCl₄. In addition, MSH administrations significantly decreased the elevation of serum alanine aminotransferase and aspartate aminotransferase activities by CCl₄. Histopathological observation indicated that all MSH treatments significantly reduced the increase of degenerated hepatocytes, inflammatory cell infiltration, and histological activity index score by CCl₄. Moreover, all MSH administrations reduced the elevation of malondialdehyde contents, and ameliorated the reduction of hepatic glutathione contents, superoxide dismutase activity, and catalase activity. Among the various mixing ratio of MSH combinations, MSH 1:1 and 2:1 showed the most potent anti-oxidative stress, and hepatoprotective effect. Conclusion : Present results suggest that 1:1 and 2:1 combinations of MSH is promising herbal formulation with the hepatoprotective effect against oxidative stress.

For the screening of anti-inflammation and antioxidative activities, ethanolic extract of 40 species of traditional herbal medicines were examined their hyaluronidase inhibitory effect and radical scavenging activity in vitro. From the result of the hyaluronidase inhibitory activity using a Morgan-Elson assay, Astragali Radix, Eucommia Cortex, Schizandrae Fructus, Scutellaria Radix, Acanthopanacis Cortex, Chaenomelis Fructus, Amomum xanthioides Wallich and Moutan Radicis Cortex showed more than 50% hyaluronidase inhibitory effects at the concentration of 10 mg/mL. In the various solvent fractions (n-hexane, chloroform, ethyl acetate, water) prepared from ethanolic extracts, the ethyl acetate fraction of all extracts tested showed strong activity. Antioxidative activity was evaluated by assaying electron-donating ability to DPPH free radical and scavenging of hydroxyl radical (ㆍOH) generated through Fenton reaction, respectively. Rubus coreanus Miq, Moutan Radicis Cortex, Paeoniae Radix Alba, Plantaginis Semen and Sorbus commixta Hedl. showed high activity more than 90%, yet similar activity to $\alpha$-tocopherol and BHA at the concentration of 1 mg/mL in electron donating activity. The scavenging effects of ethanolic extracts on hydroxyl radical were investigated using a 2-deoxyribose oxidation method and tested all extracts showed significant radical scavenging activity. The experiment was also performed to examine whether herbal medicines having significant lipid peroxidation inhibitory activity, Schizandrae-Fructus is the strongest inhibitory activity in both linoleic acid and liposome peroxidation.

The aim of this study was to investigate the protective activity of gomisin A and gomisin N, bioactive lignan components isolated from Schizandae Fructus, on hepatocyte injury induced by carbon tetrachloride($CCl_4$, 10 mM), t-butyl hydroperoxide(TBH, 0.5 mM), and D-galactosamine(GalN, 30 mM). Primary cultures of rat hepatocyte(18 h culture) were treated with $CCl_4$, TBH or GalN and various concentrations(0.1, 1, 10, $100{\mu}M$) of gomisin A or gomisin N. $CCl_4$ significantly increased the levels of lactate dehydrogenase(LDH), alanine aminotransferase(ALT), and aspartate aminotransferase(AST). These increases were inhibited by gomisin N. TBH significantly increased the level of AST; an increase that was inhibited by gomisin N. GalN markedly increased the levels of LDH and ALT, and these increases was significantly inhibited by both gomisin A and gomisin N. These results suggest that gomisin A and gomisin N have the hepatoprotective activity.

In this study, we have investigated the effect of Biphenyl Dimethyl Dicarboxylate (DDB), a synthetic analogue of Schizandrin C isolated from Schizandrae Fructus on cytochrome $P_450$ lAl and 2Bl, and the protective mechanism against $CCl_4-induced$ hepatotoxicity in rat liver. After DDB was administered into male rats for different periods of time (1~7 days) and with different doses (25, 50, 100 and 200 mg/kg), mRNA levels of CYPlAl were measured by polymearse chain reaction (PCR) and assayed the activities of CYPlAl specific ethoxyresorufin-O-dealkylase (EROD) and CYP2Bl specific benzyloxyresorufin-O-dealkylase (BROD). DDB treatment resulted in increase in CYP2Bl mRNA level and BROD activity, whereas there was no change in CYPlAl mRNA level and EROD activity. This effect of DDB was time-and dose-dependent and reached maximal level by 3 day and 200 mg/kg treatment. In addition, rats were pre-treated with DDB at doses of 25, 50 or 100 mg/kg daily for 4 days, 3-hr after final treatment on the 4th day, $CCl_4$ 0.3ml/kg was intraperitonially injected into the rats to examine the effect of DDB on $CCl_4-induced$ hepatic injury. Serum levels of ALT and AST were determined and histopathological examination was done in rat liver. Furthermore, we have measured hepatic microsomal malondialdehyde(MDA) level, a parameter of lipid peroxidation. Based on serum ALT level and lipid peroxidation, pretreatment of DDB, 50 mg/kg appeared the most protective effect against $CCl_4-induced$ heapatotoxity. These results indicate that DDB stimulates CYP2Bl mRNA level and BROD activity in time and dose dependent manner and suggest that protective effect of DDB on $CCl_4-induced$ hepatotoxicity may be mediated through free radical scavenging.

This study has been conducted to investigate the amount of residual sulfur dioxide for herbal medicines of 30 species which are purchased in 13 different regions (Bonghwa, Busan, Chunju, Jecheun, Kwangiu, Keumsan, Seoul, Taeku, Cheungdu, Xian, Beijing, Tokyo and Osaka). The sulfur dioxide residues were determined in the collected 386 samples by the modified Monier-Williams method. The residues of sulfur dioxide in 386 samples ranged from ND (under detection limit) to 2808 ppm. The sulfur dioxide in Cassiae Semon, Cinnamomi Ramulus, Cervi Cornu, Hoelen, Crataegi Fructus, Artemisiae Argyi Herba, Scolopendrae Corpus, Schizandrae Fructus and Cyperi Rhizoma were detected under the detection limit regardless of the collected regions. The sulfur dioxide residues in herbal medicines collected in domestic regions were relatively lower than those in foreign regions. There are no standards for sulfur dioxide residual limits of herbal medicines in Korea. This results will provide the scientific basis for the standardization of sulfur dioxide residues in Korea Pharmacopoeia.
