  • The purpose of this study was to investigate the effect of butanol (BuOH) fraction of Alisma canaliculatum (Ac) and/or selenium (Se) treatment on glycogen level, lipid metabolism and lipid peroxidation in streptozotocin (STZ)-induced diabetic rats. Male Sprague-Dawley rats were assigned to one of the five groups: normal, STZ-control, and three experimental groups (Ac group, Ac-Se group, and Se group). Diabetes was experimentally induced by intravenous administration of 45 mg/kg of STZ in citrate buffer. The BuOH fraction of Ac (400 mg/kg bw) was orally administered for 3 weeks. The Se group were fed a AIN-93 recommended diet mixed with Na$_2$SeO$_3$ (2 mg/kg diet). The liver glycogen level of Ac and Ac-Se groups were significantly higher, when compared with the STZ-control groups. The muscle glycogen level was not significantly differ among all groups. The levels of liver triglyceride were higher in Ac-Se group than the STZ-control group. Pancreas protein levels were significantly increased in Ac-Se group than STZ-control group. The concentration of liver malondialdehyde (MDA) was significantly decreased in Ac and Se groups and decreased in Ac-Se group. Administration of BuOH fraction of Alisma canaliculatum and selenium supplementation increased the liver glycogen and triglyceride levels, and reduced peroxidative liver damage in STZ induced diabetic rats. These results suggest that treatment with a BuOH fraction of Alisma canaliculatum in combination with selenium has no synergistic antioxidative effect. Selenium supplementation may lead a decrease MDA of liver in diabetic rats.

  • The leaves and stems of Dendropanax morbiferus were separated from organic solvents with methanol. The organic solvent fractions were fractionated with dichloromethane, ethyl acetate and butanol according to the systematic fractionation method. Oxidation in the body induces aging, and antioxidant activity has attracted the attention of many people as a preventive component to suppress negative reactions in the body. To investigate the antioxidant activity of Dendropanax morbiferus were subjected to DPPH free radical assay. In addition, acetyl cholinesterase inhibitions were performed for Alzheimer's disease as an aging neurological disease. As a result, it was confirmed that the antioxidant effect of DPPH was generally good in the antioxidant test. The ethyl acetate fractions of Dendropanax morbiferus stems and leaves were $IC_{50}=30{\mu}g/m{\ell}$. Acetyl cholinesterase inhibition experiments were carried out at a concentration of $250{\mu}g/m{\ell}$. Dendropanax morbiferus stems fractions showed dichloromethane fraction of 57.68%, which significantly inhibited the activity of acetyl cholinesterase.

  • The present investigation was designed to assess the anticancer activity of six different leaf extracts (ethyl acetate, methanol, chloroform, petroleum ether, n-butanol, and water soluble) of Abelia triflora on A-549 human lung adenocarcinoma epithelial cells. A-549 cells were exposed to $10-1000{\mu}g/ml$ concentrations of the leaf extracts of A. triflorafor 24 h and then percentage cell viability was assessed by 3-(4,5-dimethylthiazol-2yl)-2,5-biphenyl tetrazolium bromide (MTT) assay. The results showed that leaf extracts of A. triflora significantly reduced the viability of A-549 cells in a concentration-dependent manner. Decrease was recorded as 31% with ethyl acetate, 36% with methanol, 46% with chloroform, 54% with petroleum ether, 62% with n-butanol, and 63% with water soluble extracts at $1000{\mu}g/ml$ each. Among the various plant extracts, ethyl acetate extract showed the highest decrease in the percentage cell viability, followed by methanol, chloroform, petroleum ether, n-butanol, and water soluble extracts. Our results demonstrated preliminary screening of anticancer activity of different soluble extracts of A. triflora extracts against A-549 cells, which can be further used for the development of a potential therapeutic anticancer agents.

  • The micellization of TTAB(tetradecyltrimethylammonium bromide) and the solubilization of 4-halogenated phenol isomers in aqueous solution of that surfactant in water have been studied by the UV-Vis spectrophotometric method. Those properties in aqueous solutions of NaCl and n-butanol have been also measured to determine the interactions between the micelle and 4-halogenated phenols and the solubilized sites of those molecules in the micelle. The results show that the values of ${\Delta}G^o_m$ and ${\Delta}G^o_s$ are all negative and the trends of those values depend on both the kinds and the concentrations of additives. Namely, by adding NaCl both ${\Delta}G^o_m$ and ${\Delta}G^o_s$ values are all decreasing, but by adding n-butanol the ${\Delta}G^o_m$ value decreases and the ${\Delta}G^o_s$ value increases.
