Objectives : The purpose of this study was to investigate the melanogenesis inhibition effect of Saururus chinensis BAILL (SC) on in B16F10 melanoma cells. Methods : SC was fractionated ethanol extract by the hexane, ethyl acetate, butanol and water. We confirmed the inhibitory effect of tyrosinase activity and melanogenesis of all fraction samples. Results : Hexane fraction of Saururus chinensis BAILL (HSC), ethyl acetate of SC (ESC), and butanol of SC (BSC) were discovered to inhibit tysoinase activity and melanogenesis in the absence or presence of ${\alpha}$-MSH. However, water fraction of SC (WSC) did not affect tyrosinase activity and melanogenesis. In addition, all fractions did not inhibit the catalytic activity of cell-free tyrosinase from B16F10 melanoma cell lines. Conclusions : These results suggest that HSC, ESC and BSC reduce pigmentation by indirectly regulating tyrosinase.

The purpose of this study was to investigate the hypoglycemic effect of Saururus chinensis Baill in vitro and in vivo. Methanol extract of S. chinensis Baill inhibited yeast ${\alpha}$-glucosidase activity by 49.8%, which was twice as strong as that of acarbose at a concentration of 0.5 mg/mL in vitro. The effect of S. chinensis Baill methanol extract on the postprandial increase in blood glucose levels was studied in streptozotocin-induced diabetic rats using a carbohydrate load test. Oral administration of S. chinensis Baill extract (500 mg/kg) significantly decreased incremental blood glucose levels at 60 and 90 min (p<0.05) after oral ingestion of starch (1 g/kg). The area under the glucose response curve of the S. chinensis Baill group was significantly decreased compared to that of the control group (p<0.05). The effect of prolonged feeding of S. chinensis Baill was studied in an animal model of type 2 diabetes. Three-week-old db/db mice were fed an AIN-93G diet or a diet containing 0.5% S. chinensis Baill extract for 7 weeks after 1 week of adaptation. Plasma glucose, insulin, and blood glycated hemoglobin levels of the mice fed S. chinensis Baill extract were significantly lower than those of the control group (p<0.05). Therefore, we conclude that S. chinensis Baill is effective in controlling hyperglycemia in animal models of diabetes mellitus.

This study investigated the preventive effect of Saururus chinensis Baill against renal damage induced by a high-fructose diet in rats. The rats (n = 30) were fed either a cornstarch-based (65%), high-fructose (65%), or high-fructose (64.5%) diet with 0.5% S. chinensis Baill extract for 10 weeks. Twenty-four hour urine collections were obtained and the animals were sacrificed after an overnight fast. Serum urea and creatinine and urine albumin were measured using colorimetric methods, and creatinine clearance was determined. In addition, thiobarbituric acid reactive substances (TBARS), reduced glutathione (GSH), and the activity of superoxide dismutase (SOD) in the kidney were determined. Kidney samples were also examined histologically. The fructose-fed rats showed renal dysfunction, indicated by decreased creatinine clearance, increased albumin in the urine, and increased urea and creatinine in the serum. These renal function parameters were comparable to control levels in rats that consumed S. chinensis Baill. Fructose consumption increased renal TBARS and reduced GSH and SOD activity, whereas these levels were near-normal in the rats consuming S. chinensis Baill The kidneys of fructose-fed rats showed glomerular basement membrane thickening, mesangial matrix expansion, and tubule dilation. These pathological changes were not seen in the rats that consumed S. chinensis Baill. Therefore, S. chinensis Baill effectively alleviated fructose-induced renal damage in these rats, at least partially due to antioxidant activity.

Saururus chinensis (SC) belongs to the dicotyledonous plants, and its roots, leaves and flowers are white, so it is named three hundred and seconds. It is mainly distributed in Korea, China and Japan. In Korea, it is a native plant distributed in Jejudo and Jirisan areas. It has been known to improve blood circulation, anticarcinogenic effects and purge. However, studies of the efficacy on digestive system is few. This study was conducted to evaluate the effects of oral administered-SC extract in loperimide-induced constipation rats. The amount, weight and water content of the stools were measured. The number and type of stools in the large intestines were measured, and the amount of intestinal mucus was analyzed by serological analysis and histologic special staining. The severity of constipation in SC groups was significantly less than that in control group (non-SC rats). Digital Image processing also showed weaker inflammation on the large intestines of SC groups than that of control group (non-SC group). Especially, with increased dose dependent manner of SC extract, the amount and integrity of intestinal mucus increased. These results suggest that SC extract may prevent the symptoms of constipation.

Saururus chinensis (Lour.) Baill. (Saururaceae) has been used as a traditional medicine for the treatment of dysuria, leukorrhea, eczema, jaundice and ascites in Korea, China and Japan. Ethanol extract of S. chinensis was successively partitioned as methylene chloride, ethyl acetate, n-butanol and $H_2O$ soluble fractions. Among those fractions the ethyl acetate soluble fraction showed the most potent DPPH radical scavenging and superoxide quenching activities. To verify antioxidant activities of ethyl acetate fraction, we checked the activities of superoxide dismutase (SOD) and catalase, and intracellular ROS level and oxidative stress tolerance in Caenorhabditis elegans. Furthermore, to see if increased stress tolerance of worms by treating of ethyl acetate fraction was due to regulation of stress-response gene, we quantified SOD-3 expression using transgenic strain. Consequently, ethyl acetate fraction elevated SOD and catalase activities of C. elegans, and reduced intracellular ROS accumulation in a dose-dependent manner. Moreover, ethyl acetate fraction-treated CF1553 worms exhibited significantly higher SOD-3::GFP intensity.
