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.

삼백초의 수확시기와 횟수를 달리함으로써 생육과 경엽수량에 미치는 영향을 구명하여 재배법개선에 필요한 기초자료를 얻고자 시험한 결과를 요약하면 다음과 같다. 1. 1회 수확시의 생육은 7월 16일과 7월 31일 수확에서 가장 왕성하였으며, 2회 수확시는 1회 수확시기가 빠를수록 양호하였다. 2. 상품 경엽수량은 7월 31일까지는 수확시기가 늦을수록 많았으나, 이후 10월 16일에서는 41% 수준으로 감소폭이 컸다. 3. 건물율은 수확시기가 늦을수록 높아지는 경향이었다.

The water extract of Saururus chinensis was investigated for oxygen radical absorbance capacity (ORAC), reducing capacity, metal chelating activity, and intracellular antioxidant activity using HepG2 cell. When 2,2'-azobis(2-amidinopropane) dihydrochloride (AAPH) was used for the generation of peroxyl radicals in vitro, S. chinensis extract (SC-E) showed the strong and concentration-dependent scavenging activity through donating protons which could be explained by its reducing property. When hydroxyl radicals were generated in vitro through the addition of $Cu^{2+}$ and $H_2O_2$, SC-E demonstrated the antioxidant activity depending on its concentration. In HepG2 cell model, most of intracellular oxidative stress generated by AAPH was efficiently removed by SC-E. However, when $Cu^{2+}$ without $H_2O_2$ was used as an oxidant in the intracellular assay, SC-E partially reduced the oxidative stress caused by $Cu^{2+}$ in cellular antioxidant activity assay system. These results indicate that SC-E could be utilized for the development of functional foods as antioxidant resource in the near future.

This paper aims to compare and verify the antibacterial effects of cotton fabrics naturally dyed with extracts of Ulmus davidiana var. japonica Nakai, Caesalpinia sappan, Saururus chinensis, and Artemisia princeps against antibiotic-resistant strains of bacteria. After natural dyeing of the test fabric, Al, Cu, Fe mordants were used. The color fastness against washing, rubbing, and perspiration of the cotton fabrics dyed with the 4 types of extracts were mostly excellent. However, the color fastness against light showed poor results for all four types. As for the antibacterial test method, MRSA (ATCC 33591) was applied to the cotton fabrics dyed with the four kinds of extracts and cultured for 24 hours. After that, the bacteria that proliferated on the fabrics were collected and spread on a solid medium. The bacteria were measured to find out the bacteriostatic reduction rate for the antibiotic-resistant strains. As a result of the analysis, all four extracts showed a high bacteriostatic reduction rate of more than 99% when the copper mordant was used. Even with the lack of a mordant, the bacteriostatic reduction rate was high, at 99.9% for Caesalpinia sappan and 94.6% for Saururus chinensis.

초미세 분쇄를 하였을 때 입자가 작아질수록 추출수율이 높아져 약 2.5배 높은 추출수율을 나타내었다. 일반 분쇄한 시료 추출물에서 69.8%의 전자공여능 억제효과가 관찰되었고, 미세분쇄와 초미세분쇄 추출물에서는 각각 70.7과 83.8%의 억제효과를 나타내었다. 일반분쇄 추출물과 미세분쇄 및 초미세분쇄 후 추출물 모두 97% 이상의 높은 ABTS 억제효과를 나타내어 분쇄 방법에 따른 항산화력의 차이는 거의 없었다. 일반 분쇄한 시료 추출물 보다 미세분쇄와 초미세분쇄 추출물에서 더 높은 PF값을 확인하였으며, 50% ethanol 초미세분쇄 추출물에서 1.8 PF로 가장 높은 항산화력을 나타내었다. 미세분쇄와 초미세분쇄 추출물에서는 일반분쇄 추출물에 비해 입자크기가 작아질수록 TBARS 억제율이 높아지며, 물 추출물보다 ethanol 추출물의 효과가 더 우수한 것으로 확인되었다. Xanthin oxidase 저해의 경우 초미세분쇄 후 효소억제 증대 효과를 확인할 수 있었다. Angiotensin converting enzyme 억제활성은 일반분쇄 추출의 경우 물 추출물에서는 억제활성이 나타나지 않았고, 50% ethanol 추출물에서 24%의 억제율이 확인되었다. 또한, ethanol 추출물의 억제효과가 물 추출물에 비해 상대적으로 우수하였다. 50% ethanol 초미세분쇄 추출물에서 Staphylococcus aureus, Escherichia coli에 대해서 아주 약한 항균효과를 나타내었을 뿐 나머지 추출물에서의 항균효과는 거의 관찰되지 않았다.

Saururus-chinensis was used for the natural due stuff extraction and concentration to produce the condensed dye liquid. Using this liquid, the silk and the cotton fabrics were dyed. And then the K/S value, color difference were measured in order to determine the dye ability and the antimicrobial activity. The K/S values of silk were much higher than those of cotton. In terms of the silk fabric, the Al, Cr-premordanting and Fe, Cu-simmordanting method was most efficient of the mordanting method. The various suface colors on the dyed fabric were resulted according to used mordants and mordanting methods. The dye fastness was significantly improved when mordants were added. Among them, Al-mordant improved more than 1 level. The Cu, Fe-mordants showed the greatest antimicrobial activity on both of mordant treat silk and cotton.

In order to find the new hepatoprotective agents from natural products, the isolation and identification of biological active components of the roots of Saururus chinensis has been carried out. A MeOH extract of this plant showed the significant hepatoprotective effect on tacrine-induced cytotoxicity in Hep G2 cells. Five lignans including sauchinone, manassantin A, manassantin B, saucerneol B, and di-O-methyltetrahydrofuriguaiacin B were isolated and identified by spectroscopic evaluation. (omitted)
