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.

This experiment was conducted to determine the essential oil content and the aromatic constituents in the leaves of Saururus chinensis Baill, Angelica dahurica Fischer and Cnidium officinale Makino. Volatile aromatic compounds in three aromatic medicinal plants were extracted with steam distillation extraction method and identified by GC/MS. Major aromatic compounds in Saururus chinensis Baill were 1,6-octadien-3-ol, 1, 3-benzodioxole, myristicin, ${\alpha}-cadinol$ and patchouene. Major aromatic compounds in Angelica dahurica Fischer were terpinolene, 3-carene, ${\beta}-caryophyllene$, ${\beta}-cubebene$, butylated hydroxy toluene, caryophyllene oxide, piperonal, and in Cnidium officinale Makino were aristolene, benzocycloheptene, ylangene, valencene, ${\beta}-cedrene$, satene, and menthofuran. Essential oil content was highest in Saururus chinensis plant.

The effects of Saururus chinensis Baill administration on the biochemical parameters of function in liver of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) treated rats were investigated. Saururus chinensis Baill (200mg/kg) was administered into rats intraperitoneally for four weeks, seven days after the injection of TCDD(1 ${\mu}g/kg$). We examined the antioxidative enzymatic activity by measuring the level of AST and ALT in serum and SOD, Catalase, GPx, GSH and GSSG in liver tissue of rats. STT group showed 70.7% of inhibitive effect in AST acrivity compared to TTA group. ALT level of STT group was decreased to the level of NTT group. SOD and Catalase in TTA group were lower than in NTT group, but SOD and Catalase in STT group were increased by 82% and 55.45% respectively compared to TTA group. GSH contents in STT group were 74.20% increased compared to TTA group. GSSG contents in STT group were 61.08% decreased compared to TTA group. These results suggest that Saururus Chinensis Baill has a potent hepathprotective effect against TCDD intoxicated rats.

This study was carried out to investigate the inhibitive effect of Saururus chinenesis Baill (SCB) on lipid peroxidation in Sprague-Dawely rat (SD-rat) accutely exposed to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). Saururus chinenesis Baill (200 mg/kg) was administered into rats intraperitoneally for four weeks, seven days after the injection of TCDD (1 ${\mu}$g/kg). we examined th lipid parameters by measuring the levels of Total Cholestero, Triglyceride(TG), HDL-Cholestero, and LDL-Cholesterol in serum and Malone Dialdehyde (MDA) in liver tissue of rats. Cholesterol was siginificantly elevated in TCDD-treated abnormal group (TTA). The higher level of HDL-Cholesterol was found in Saururus chinenesis Baill and TCDD administered group (STT), which showed the lower levels of Total-Cholesterol and LDL-Cholesterol. TG content in the TTA was 34.84% increased compared to Non TCDD-treated group (NTT). That of STT was inhibited by 18.90% compared to TTA. MDA content in the TTA was 44.72% increased compared to NTT. That of STT was inhibited by 17.14% compared to TTA.

The optimization of the addition ratios of Houttuynia cordata, Saururus chinensis, and Polygonatum odoratum var. pluriflorum hot water extract to Houttuynia cordata beverage was evaluated by applying response surface methodology. The quality characteristics of a selected best product were investigated. Sweet, savory, and fishy taste, and overall acceptability were optimized by response surface methodology using a central composite design. The concentration of effect of Houttuynia cordata, Saururus chinensis, and Polygonatum odoratum var. pluriflorum hot water extract was modeled using an equation. Hot water extracts of Houttuynia cordata ($1.75{\sim}1.89%$), Saururus chinensis ($1.03{\sim}1.04%$), and Polygonatum odoratum var. pluriflorum ($2.17{\sim}2.31%$) represented the optimal concentration conditions to obtain the best taste. The physical and chemical characteristics of the beverage manufactured at optimized conditions were pH 4.18, soluble solids 0.41 $^{\circ}Brix$, total acidity 0.21%, color value ($L^*$ value 40.08, $a^*$ value 4.53, and $b^*$ value 10.69), total polyphenol 54.63 mg/L, and electron donating ability 26.98%.

In order to determine the optimum level of three major fertilizers for Saururus chinensis, we applied to the soil at a rate of N(0, 4, 7, 10kg/10a), P$_2$O$\_$5/(0, 1.5, 3, 4.5kg/10a) and K$_2$O(0, 3, 6, 9kg/10a) prior to seeding. Regarding physical properties after the application, the values of pH, OM, Mg, CEC and EC were higher than those of the pre-application, but the contents of P$_2$O$\_$5/, K and Ca were lower. With application of three major fertilizers, dry weight of leaves per 10a was 26∼108kg greater than that of control(281kg) and dry weight of root tuber was higher by 19∼157kg than that of control(610kg). In regression equation of fertilizer recommendation for two-year-old Saururus chinensis, the optimum level of N-P$\_$2/O$\_$5/-K$\_$2/O fertilizer was determined by 7.1, 2.5, 4.2kg/10a, respectively.

Manassantin B, a dilignan isolated from Saururus chinensis, significantly inhibited proliferation in HSC-T6 cells in concentration- and time-dependent manners. In addition, treatment of HSC-T6 cells with manassantin B changed cell morphology from flattened myofibroblastic membranous morphology, representing activation state, to slender shape, representing quiescent state. Furthermore, manassantin B effectively reduced collagen content in HSC-T6 cells. These results suggested that manassantin B exerted antifibrotic activity in HSCT6 cells, in part, via inhibition of cell proliferation and decrease of collagen production.

Two dineolignans (1,2) with nitric oxide inhibitory activities were isolated from Saururus chinensis (Saururaceae) using silica gel column chromatography. Although the structures, saucernetin-7 (1) and -8 (2), have been already reported, NMR assignment of the two compounds was completed aided by 2D-NMR spectroscopy including $^1H-^1H$ COSY, $^1H-^{13}C$ COSY, HMBC and NOESY NMR spectra. Compounds 1 and 2 exhibited significant nitride oxide inhibitory activity in LPS-induced RAW 264.7 cells with $IC_{50}$ values of $11.3{\mu}M\;and\;7.1{\mu}M$, respectively.

In order to enhance the extraction efficiency of flavonoid from Saururus chinensis, carbohydrate-hydrolyzing enzyme Viscozyme L aided extraction techniques have been studied. Then flavonoid composition, as well as quercetin, were also identified using UV/Vis, HPLC/MS, and ¹H-NMR. The results showed that favorable extraction conditions were Viscozyme L concentration of 0.25 mg/g, pH 4.2, reaction at 45 ℃ for 12 h. Under the favorable extraction condition, total flavonoid yield (37.9 mg/g) and quercetin yield (0.86 mg/g) increased by about 2.0 and 9.6 times, respectively, compared to control group. Interestingly, as a significant flavonoid of S. chinensis, flavonoid glycones rutin was hydrolyzed to aglycones quercetin by Viscozyme L. These findings provide scientific and theoretical support for the development quercetin-rich products, which was quickly absorbed by the human body than rutin.

Dyeability and antimicrobial activity of Saururus chinensis on to silk and cotton fabrics has been studied. The dyestuff was extracted with distilled water. Silk fabric showed higher K/S value than cotton fabric at the same condition. And with the simmordanting by Fe, Cu gave good improvements of the K/S values. Surface color of dyed fabrics was various according to the used mordants: Cr mordanted fabric was to be cleared, Fe mordanted fabric was the greatest color difference. The fastness was significantly improved in mordanting. The Fe, Cu mordanted silk fabrics was the greatest antimicrobial activity.
