This study was carried to investigate the effect of illite addition on the growth, bioactive components and volatile compounds of leaf on Saururus chinensis Baill cultivation in greenhouse. Illite addition on Saururus chinensis Baill cultivation resulted no significant effects on the aerial part. However, the root part was highest in 5% illite addition group. Crude oil and ash amount increased as illite additives was increased. Ca of inorganics and free sugars contents were highest in 5% and 20% illite addition, respectively. Hyperoside and isoquercetin of available component on leaf were highest in 5% illite addition group, 4.02mg/g and 4.31mg/g, respectively. The volatile compounds in Saururus chinensis Baill leaf cultured with illite addition amounts were isolated by solid-phase microextraction fiber (polydimethysiloxane $65{\mu}m$) and identifed by gas chromatogtaphy mass spectrometry. As the results, the 22 volatile compounds were identified from in Saururus chinensis Baill leaf and major volatile compounds were the ${\alpha}$-cadinol (18.50%), myristicin (16.46%), methyl-9-methyl-tetradecanoate (10.22%), and ${\gamma}$-muurolene (9.75%). Especially, the content of ${\alpha}$-cadinol was highest in 5% illite addition group and ${\gamma}$-muurolene on overall illite addition group was lower than no addition group.

The growth of stem and leaves in Saururus chinensis. in the 2nd year was markedly increased comparing to that in the 1st year, however the growth in the 3rd you was not increased significantly. The growth in the 1st yew was greater in low planting density, while the growth in the 3rd year decreased in higher planting densities. The num- ber of leaves and stems per unit area increased in higher planting densities and later years. The weight of stem and leaves in Saururus chinensis was higher at the highest planting density in the 1st yew, at $40{\times}10cm$ planting in the 2nd year and at $40{\times}20cm$ planting in the 3rd year. The weight of rhizome in Saururus chinensis increased greatly in the 2nd you comparing to that in the 1st year, but the increase was insignificant in the 3rd year. The weight of rhizomes in Saururus chinensis showed significant interaction between planting densities and years showed highly significant difference.

Saururus chinensis is used as a raw material of an anti-rheumatic, poultice, sedative and stomachic. The tea of dried Saururus chinensis leaves has a function of relaxing pains in back and breast and of treating stomach ailments. The plant has the functions of anti-inflammatory, depurative, diuretic, febrifuge and refrigerant. The extraction of functional material is carried out by methanol and ethanol solvents. Mechanochemical grinding is applied as a pretreatment process before extraction to enhance the extraction efficiency by increasing the surface area of the materials while changing the chemical properties of the materials. Extraction of functional materials from the Saururus chinensis after grinding as a pretreatment using the mechanochemical technology was accomplished in this study to investigate the effect of grinding on the antioxidant activities of the extract. Saururus chinensis was ground by the planetary ball mill and the morphology was analyzed by SEM. Mechanochemical pretreatment increased the yields of functional materials from 5.9 g to 6.4, 7.0, and 8.1 g after grinding of 30 minutes, 1 hour and 2 hours, respectively. Nitrite scavenging ability increased from 53.0-71.0% to 61.0-79.0% for the methanol extraction in the solution of pH 1.2. Also, Electron donating abilities were increased from 7.90-33.51% to 11.97-38.51% for the methanol extraction. The extract concentration for the half inhibition of DPPH radicals was reduced from $278{\mu}g/mL$ in the original sample to $263{\mu}g/mL$ in the sample after grinding for the methanol extraction.

This study investigated on the nutritional components and physiological activity of four wild vegetables namely Salvia plebeia R. Br., Angelica acutiloba, Gynura procumbens and Saururus chinensis Baill for the development of representative wild vegetables in Chungbuk. Salvia plebeia possessed the highest radical scavenging activity and beta-carotene, but exhibited the lowest α-glucosidase inhibitory activity compared to the other three vegetables. Angelica acutiloba showed high crude protein content and α-glucosidase inhibitory activity, but contained low total polyphenol content, radical scavenging ability and beta-carotene compared to the other three vegetables. Gynura procumbens showed high mineral content, beta-carotene, vitamin K1 content and α-glucosidase inhibitory activity, but showed the lowest total polyphenol content and radical scavenging ability compared to the other three vegetables. Saururus chinensis showed high crude fiber content and total polyphenol content, but contained the lowest mineral and vitamin K1 content. To conclude, it is suggested to use Salvia plebeia or Saururus chinensis as antioxidant food materials and Angelica acutiloba and Gynura procumbens as food materials and sources of α-glucosidase inhibitors. In particular, it is believed that Saururus chinensis, which possessed high content of crude fiber, is suitable for low-calorie food materials such as diet products.

Elicitor treatment was performed to increase the anti-inflammatory activity of useful biological sources. The result showed that elicitor-treated Saururus chinensis leaf extracts positively affected nitric oxide (NO) production, and the expression of inducible NO synthase and cyclooxygenase-2 compared to extracts not exposed to elicitor treatment. This finding identified elicitor treatment as a suitable strategy for increasing the biological activity of S. chinensis. Therefore, elicitor-treated S. chinensis is useful both as health functional and medicinal materials.

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.

Saururus chinensis Baill (Saururaceae) is a perennial plant that has been used for therapy of edema, jaundice and gonorrhea in Korean folk medicine. This study was carried out to investigate the inhibitory effects of Saururus chinensis Baill(SCB) on hepatoprotective effects in accutely Carbone Tetrachloride ($CCl_4$) treated rats. Saururus chinensis Baill (100 mg/kg) was administered into rats intraperitoneally for 2 weeks, after the injection of CCl4 (3.3 ml/kg). We dxamined the biochemical parameters by measuring the levels of Aspartate aminotransferase (AST), Alanine aminotransferase (ALT), Total cholesterol, Triglyceride (TG), HDL-cholesterol, and LDL-cholesterol in serum and Malonedialdehyde (MDA) in liver tissue of rats. cholesterol was siginificantly elevated in $CCl_4$-treated abnormal group (CTA). The higher level of HDL-cholesterol was found is Saururus chinensis Baill and CCl4 administered group (SCT), which showed the lower levels of Total-cholesterol and LDL-cholesterol. TG content in the SCT was decreased compared to CTA by 0.93 times. MDA content in the SCT was inhibited compared to CTA by 33.00%. These findings indicate that Saururus chinensis. Baill may have a protective effect against CCl4-treated hepatotoxicity in rats.
