Melanogenesis refers to the biosynthesis of melanin pigment in melanocytes. Melanogenesis is controlled by the intra- and extracellular environments. In the present study, to develop a new whitening agent, it was investigated the antioxidant activity and the inhibitory effect of Ailanthi Radicis Cortex extract on tyrosinase activity and on melanogenesis in the B16/F1 melanoma cells. The inhibition ratio of tyrosinase activity of ethylacetate fraction from Ailanthi Radicis Cortex was higher than that of arbutin. The ethylacetate fraction showed scavenging activities of 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals and superoxide anion radicals in a dose dependent manner. The highest inhibitory activity of melanogenesis was also in ethylacetate fraction ($40.0{\pm}5%$ at the concentration of $400{\mu}g/ml$). This study demonstrates that the Ailanthi Radicis Cortex extract might be used to be a potential agent for skin whitening.

During the serial attempts to identify the chemical and biological characteristics of Ailanthi Cortex Radicis, the root bark of Ailanthus altissima (Simaroubaceae), we find out the serious toxic effect on kidney by chloroform fraction of the methanolic extract of the herb drug. The toxicities were revealed as the increase of urea nitrogen amount in blood and lactate dehydrogenase and ${\gamma}-glutamyltransferase$ activities in urine and the decrease of the concentration of glutathione and both of protein bound and non-protein bound -SH in kidney tissue.

The cytotoxic activities of methanolic extract and its fractions of Ailanthi Cortex Radicis and column chromatographic eluates of its dichloromethane fraction (DCM fr.) were investigated. DCM fr. Showed the strongest cytotoxicity against hepatoma cells. Furthermore, the active equates 1-3, 8 and 9 were obtained. Effects on free radical generation and the growth of vascular endothelial cells were tested to elucidate the action mechanism of anticancer activity. Eluates 1-3 stimulated free radical generation, while eluates 8 and 9 showed no changes. Especially, eluates 8 and 9 efffectively inhibited the proliferation of vascular endothelial cells in a dose- dependant manner. It is speculated that the anticancer effects of eluates 1-3, 8 and 9 might be due to free radical generation and inhibition of endothelial cell growth, respectively.

For the biological survey, effects of Ailanthi Cortex Radicis, the root bark of Ailanthus altissima(Simaroubaceae) on epoxide hydrolyzing enzymes were checked. The methanolic extract and its chloroform fraction were shown to activate the liver metabolizing enzyme system including epoxide hydrolase system which was monitored by activities of transaminase, lactate dehydrogenase, alkaline phosphatase and epoxide hydrolase system in bromobenzene treated rats. But they showed no effect on glutathione S-transferase activity.

This study was performed to investigate the antidiabetic study effect in ethanol extract of Ailanthicortex(A.C) radici in Streptozotocin(STZ)-induced diabetic rats. Diabetes was induced by intravenous injection of STZ at a dose of 45mg/kg dissolved in citrate buffer. The ethanol extract of A.C radici was orally administrated once a day for 7 days at a dose of 500mg/kg. The content of serum glucose, triglyceride(T.G), total cholesterol were significantly decreased in treated group compared to the those of STZ-control group. The content of hepatic glycogen and activity of glucokinase(GK) were significantly increased in treated group compared to the those of STZ-control group. but activity of glucose-6-phosphate dehydrogenase(G-6-PDH) was significantly increased. These results indicated that ethanol extract of A.C would have antidiabetic effect in STZ-induced diabetic rats.

Ailanthus altissima has been used to settle an upset stomach, to alleviate a fever, and as an insecticide. We reported that the water extract of A. altissima induced apoptotic cell death in HL-60 human leukemia cell line. Here, we showed the dose-dependent inhibitions of cell viability by the extract, as measured by cell morphology. The cell cycle control genes are considered to play important roles in tumorigenesis. The purpose of the present study is also to investigate the effect of A. altissima on cell cycle progression and its molecular mechanism in the cells. The level of p21 protein was increased after treatment of the extract, whereas both Bcl-2 and Bax protein levels were not changed. These results suggest that A. altissima induces apoptotic cell death via p21-dependent signaling pathway in HL-60 human leukemia cell line which delete wild type p53. G1 checkpoin related gene products tested (cyclin D3, cyclin dependent kinase 4, retinoblastoma, E2F1) were decreased in their protein levels in a dose-dependent manner after treatment of the extract. Taken together, these results indicate that the increase of apoptotic cell death by A. altissima may be due to the inhibition of cell cycle in HL-60 human leukemia cell line

Purpose : This study was conducted to investigate the antimicrobial effects of Astringent medicinals against vaginal microbe. Methods : Staphylococcus aureus, Methicillin-resistant Staphylococcus aureus, Candida albicans and Gardnerella vaginalis were used for vaginitis-induced microbe. Lactobacillus gasseri, Streptococcus spp. and Escherichia coli HB101 were used for normal vaginal florae. And Astringent medicinals (Rubi Fructus, Tritici Immatri Semen, Corni Fructus, Nelumbinis Semen, Mume Fructus, Schizandrae Fructus, Ailanthi Radicis Cortex, Galla Rhois, Myristicae Semen, Terminariae Fructus, Rosae laevigatae Fructus, Ephedrae Radix) were used in this study. Antimicrobial activities were tested by optical density and colony test in vitro. And then wee valuated the antimicrobial effects in comparison with optical density and colony test. Results : The optical density and colony test showed that Terminariae Fructus and Galla Rhois among Astringent medicinals had the antimicrobial effects. Teminariae Fructus had the antimicrobial susceptibility and selective toxicity against Candida albicans and Gardnerella vaginalis of vaginitis-induced microbe. Galla Rhois had the antimicrobial susceptibility and selective toxicity against Staphylococus aureus, Methicillin-resistant Staphylococus aureus, Candida albicans and Gardnerella vaginalis of vaginitis-induced microbe. Conclusion : According to these results, we can suggest that Terminariae Fructus and Galla Rhois among Astringent medicinals be available to the antimicrobial agent of vaginitis-induced microbe in vitro.
