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.

Schizandrae Fruits has been used as a traditional Oriental medicine for treatment of many stress-induced diseases. In the present study, we investigated inhibitory activity of enzymatic hydrolysate of Schizandrae fructus (SC-EX) in growth of tested intestinal microorganism and activity of bowel inflammation related enzyme. SC-EX was added to the proteose peptone-yeast extract-fildes (PYF) media to investigation the effect on the growth of type culture of intestinal microorganism. The growth of lactic acid bacteria such as Bifidobacterium species and Lactobacillus species was accelerated by more than 3% concentration of SC-EX. But, growth of harmfulness bacteria such as E.coli, Clostridium sp. Staphylococcus sp. Streptococcus sp. was inhibited by more than 3% concentration of SC-EX. Also, SC-EX was exhibited a concentration-dependent inhibitory activity of the bowel inflammation related enzymes. The SC-EX was showed 76% and 92% inhibitory activity of 5-lipoxygenase and cyclooygenase at 5% additional concentration respectively. Our results indicated that SC-EX may possess improvement effect on the intestinal flora and Anti-inflammatory effect on the bowel.

Objectives: Schizandrae fructus (Schizandra chinensis) is one of very common herbs, it is known as natural antioxidants, anti-inflammatory agent. Also some reports show that its extract works to regulate of dyslipidemia. This study was designed to investigate the effects of Schizandrae fructus chloroform fraction (SFCF) on serum lipid levels in dyslipidemic mice. Methods: The levels of total cholesterol, high density lipoprotein-cholesterol, triglyceride, aspartate aminotransferase (AST), alanine aminotransferase (ALT), fasting blood glucose in serum were measured. Histopathological and gene expression changes in liver tissue were also observed. Results: Oral administration of SFCF lowered levels of total cholesterol and triglyceride, which were elevated by high-fat diet. But SFCF did not affect on weight changes and serum AST, ALT levels in dyslipidemic mice. After carrying out gene ontological analysis, large numbers of genes in high-fat diet group were up-(347) or down-regulated (235). In SFCF treated mice, some changed expression of the genes was restored to normal levels, with a recovery rate of 17%. And it seems that fatty acid biosynthesis pathway was one of important key pathways to recovery. Conclusions: SFCF has beneficial effect on dyslipidemia, and could be used to prevent and treat cardiovascular disease.

The fruits of Schisandra chinensis and Prunus mume have been traditionally used in the Oriental countries as an astringent against diarrhea and abdominal pain, a protectant for liver disease, an antimicrobial, and a blood tonic. However, little is known about the extract of Schizandrae Fructus and Mume Fructus (SMF-Ex) on dextran-sulfate sodium (DSS)-induced colitis in mice. In this study, we investigated the protective effects of SMF-Ex on DSS-induced colitis in mice. An experimental colitis was induced by daily treatment with 5% DSS. SMF-Ex was orally administrated the single dose (80 mg/kg, body weight/day) for 7 days with one time per day. SMF-Ex reduced significantly clinical sign of DSS-induced colitis, including body weight loss, shorten colon length, increased disease activity index (DAI), and histological colon injury. SMF-Ex also inhibited significantly nitric oxide (NO) and prostaglandine $E_2$ ($PGE_2$) productions in DSS-induced colitis mice. Furthermore, SMF-Ex increased significantly an superoxide anion (SOD), catalase, and glutathione peroxidase (Gpx) activity of the colon tissue in DSS-induced colitis mice. These results suggest that SMF-Ex administration could reduce significantly the clinical signs and inflammatory mediators, and increase antioxidant activity in DSS-induced colitis model mice and is a good candidate for further evaluation as an effective anti-ulcerative agent.

The effects of aqueous extract of Schizandrae Fructus (AESC) on lead (Pb)-induced changes of monoamine neurotransmitters in the hippocampus (HIP) of adult rats were investigated. Male Sprague-Dawley rats were received intraperitoneal (i.p.) administration of Pb acetate (5 mg/kg/d) for 28 days and sacrificed 7 days after the last administration. Concentrations of norepinephrine (NE), dopamine (DA), serotonin (5-HT), 5-hydroxyindole acetic acid (5-HIAA) in HIP were measured by HPLC. There were significant decreases of NE, DA, 5-HT and 5-HIAA in Pb treated rats (P < 0.05), while pretreatment with AESC (100 mg/kg/d or 300 mg/kg/d, p.o., 2 h before Pb) greatly inhibited the decrease of monoamine transmitters, respectively (P < 0.05). Also, AESC (300 mg/kg/d) significantly increased the reduction of glutathione contents and superoxide dismutase activities in HIP induced by chronic Pb. These results suggest that AESC ameliorates Pb-induced depletion of monoamine neurotransmitters in HIP through its antioxidant activity.

The effect of Schizandrae fructus extract on the physiological properties of Saccharomyces cerevisiae was investigated. S. cerevisiae was inoculated into glucose broth, added with Schizandrae fructus extract, 0, 0.01, 0.1, 0.5 and 1%(w/v), respectively. And a 96 hours incubation was followed to investigate the changes in the growth, alcohol production, alcohol dehydrogenase and pyruvate decarboxylase activities of S. cerevisiae. The growth of S. cerevisiae was more pronounced in the broth containing 0.1 and 0.OlfS Schizandrae fructus extract than in the control. The growth was, however, inhibited in the broth containing 0.5 and 1% of the extract. The content of alcohol produced by S. cerevisiae also showed very similiar results with those of the yeast growth by addition of Schizandrae fructus extract. Alcohol dehydrogenase activities of S. cerevisiae cultured in broth treated with the extract of 0.1% and 0.01% increased by 25% and 18% than those in control group. Pyruvate decarboxylase activities in 0.1% and 0.01% treatments increased to 1.32 and 1.26 times. The activities in 0.5% and 1% treatments, however, decreased by 30% and 44%.

Objectives : Although the anti-obesity effect of Schizandrae Fructus water extract has been demonstrated, its underlying mechanism is still unclear. Therefore, we aimed to evaluate the anti-obesity effect of Schizandrae Fructus water extract through the p-AMP-activated protein kinase (p-AMPK), sirtuin1 (Sirt1), and peroxisome proliferator-activated receptor-gamma coactivator 1α (PGC-1α) signaling in 60% high-fat diet (HFD)-induced obese mouse model. Methods : Male C57BL/6 mice were divided into four groups. The Normal group was fed a normal diet and the obese groups were fed 60% HFD. Except for the Control group, the GG group was supplemented with 0.5% Garcinia gummigutta and the SCW group was supplemented with 0.5% Schizandrae Fructus water extract. After 6 weeks, obesity-related biomarkers in serum were measured and the expressions of protein for lipid-related factors in liver tissue were analyzed by western blot. Results : Treatment with SCW significantly down-regulated body weight compared to the Control group. SCW down-regulated levels of triglyceride and total cholesterol in serum and significantly increased p-AMPK, Sirt1, and PGC-1α in liver tissue. In addition, the expressions of fatty acid oxidation-related proteins such as peroxisome proliferator-activated receptor α (PPARα), carnitine palmitoyltransferase 1A (CPT-1A), uncoupling protein 1 (UCP1), and uncoupling protein 3 (UCP3) were significantly up-regulated. However, fatty acid synthesis-related proteins including sterol regulatory element-binding protein-1 (SREBP-1), phospho-Acetyl-CoA Carboxylase (p-ACC), and fatty acid synthase (FAS) were significantly down-regulated. Conclusions : Taken together, SCW treatment showed anti-obesity effect by regulating both fatty acid oxidation-related and fatty acid synthesis-related proteins through AMPK/Sirt1/PGC-1α signaling in 60% HFD-induced obese mice.

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.
