The author examined whether the methanol extracts of Opuntia ficus-indica fruit and Saururus chinensis have the inhibitory action on xanthine/xanthine oxidase (X/XO)-, $FeCl_2/ascorbic$ acid- and arachidonic acid-induced neurotoxicity in mouse cortical cell cultures. The methanol extracts ($10\;{\mu}g/ml{\sim}1\;mg/ml$) of Opuntia ficus-indica and Saururus chinensis were exhibited 53-89% and $48{\sim}100%$ inhibitory action on X/XO-induced neurotoxicity, respectively. At the range of same concentration, both extracts also attenuated the $FeCl_2/ascorbic$ acid-induced neurotoxicity by $35{\sim}100%$ and $15{\sim}98%$, respectively. In arachidonic acid neurotoxicity, the methanol extract (1 mg/ml) of Opuntia ficus-indica and Saururus chinensis reduced neuronal injury by 22% and 38%, respectively. These results suggest that Opuntia ficus-indica fruit and Saururus chinensis may contribute the neuroprotection in certain free radical-mediated neuronal injury.

Bioactive components of ultra-fine ground Saururus, the extraction yield increases when the leaves are ultra-fine ground. Comparison of normal-ground and ultra-fine ground Saururus chinensis leaves showed that the solid content and antiinflammatory activity of ultra-fine ground extracts was higher than that of normal-ground extracts. Lipopolysaccharide (LPS)-stimulated Raw 264.7 cells were treated with different concentrations of Saururus chinensis extract and the amount of nitric oxide (NO) was determined; LPS-treated cells produced 2 times more NO than cells that were not treated with LPS. Moreover, the NO production in cells treated with Saururus chinensis extract was inhibited in a concentration-dependent manner. Because the stimulant-induced NO production is regulated by the inducible nitric oxide synthase (iNOS), we measured the iNOS protein level to elucidate the mechanism by which the NO production was inhibited. We found that the amount of iNOS decreased dose-dependently. It was reduced by 53% at a Saururus chinensis extract concentration of $100{\mu}g/mL$. The protein expression of cyclooxygenase-2 (COX-2) in LPS-treated Raw 264.7 cells was inhibited by 31% at $100{\mu}g/mL$ of Saururus chinensis extract. Gel shift of the nuclear factor kappa B-DNA complex occurred in LPS-treated cells and the intensity of the band decreased gradually in a concentration-dependent manner. Ultra-fine ground Saururus chinensis extract had a concentration-dependent inhibitory effect on the production of prostaglandin $E_2$, tumor necrosis factor ${\alpha}$, interleukin $1{\beta}$ (IL-$1{\beta}$), IL-6, and IL-8 in LPS-treated Raw 264.7 cells, i.e., at $50{\mu}g/mL$ of Saururus chinensis extract, their levels were decreased by 53, 67, 52, 37, and 21% respectively.

This study was conducted to investigate the antimicrobial, antivirus properties of Saururus chinensis extracts. The n-hexane extracts from Saururus chinensis showed the active antimicrobial activity against gram-positive bacteria. Minimum inhibitory concentration (MIC) of Saururus chiensis n-hexane extracts was 1.25 mg/ml against B. subtilis and 2.5 mg/ml against S. aureus. The cytotoxicity effects on MDBK (Madin-Darby bovine kidney) cell were observed at the various n-hexane extract concentrations. In $TCID_{50}$ assay, 0.6 mg/ml of n-hexane extracts decreased BVD (bovine viral diarrhea) virus by 1.4 log, whereas other extracts did not show antiviral activity. In this study, The results suggested that n-hexane extracts and fractions of Saururus chinensis can be a candidate materal of feed additive to chemical antibiotics and antivirus substances.

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.

Saururus chinensis is a commonly used folk herb for the treatment of edema and liver diseases in Korea. To study the biological activity of Saururus chinensis in bone metabolism, we evaluated the effect of its extracts on osteoclast differentiation in vitro using primary mouse bone marrow-derived macrophages. Methanol extract (ME) from dried roots of Saururus chinensis was partitioned into methylene chloride (MF), ethyl acetate (EF), n-butanol (BF) and water fractions (WF). Tartrate-resistance acid phosphatase (TRAP) activity assay and western blot analysis were performed to determine the effect on osteoclast differentiation and mitogen-activated protein (MAP) kinases activation. ME, MF and EF dramatically inhibited receptor activator of ${NF-kB}$ ligand (RANKL)-induced formation of multinucleated osteoclasts and activation of MAP kinases. This study firstly demonstrated that ME, MF and EF of Saururus chinensis have the potential to inhibit the osteoclast differentiation, which results from the inhibition of MAP kinases activations in part.

홍삼(panax ginseng C.A. Meyer) 추출물 단독의 항산화 활성과 홍삼추출물에 삼백초(Saururus chinensis(Lour.) Baill.)와 복분자(Rubus coreanus Miq.) 추출물을 농도별로 보충 급여 하였을 때 나타나는 상승효과를 알아보기 위하여 Sprague Dawley rat에 이들 추출물을 8주간 섭취시킨 후 희생시켜 간장 cytosol중의 superoxide dismutase, catalase, glutathione peroxidase, GST 등의 항상화 효소계 활성을 측정하였다. 그 결과, 홍삼급여군의 superoxide dismutase, catalase, glutathione peroxidase의 효소활성이 대조군에 비해 농도 의존적으로 높았다. 특히 홍삼 단독보다는 삼백초와 복분자를 보충급여시 상승효과가 높았으며 급여기간이 길수록 그 효과가 높았다.

Obesity increases the risk of many adult diseases, such as atherosclerosis, diabetes, hypertension, ischemic heart disease and breast cancer. Inhibition of adipogenesis is an effective way in the anti-obesity management. Because of main components of Saururus chinensis is flavonoid, it has been showed some improvement by its antioxidant effects on the atherosclerosis, heart disease and diabetic hyperlipidemia. But mechanism of anti-obesity effect of S. chinensis is not clear. We investigated the effects of ethanol extracts of S. chinensis on adipogenesis in the 3T3-L1 pre-adipocyte. The 3T3-L1 cell line is commonly used to study adipogenesis in vitro. In this study, ethanol extracts of S. chinensis significantly decrease the lipid accumulation in the 3T3-L1 cells proved by measuring triglyceride contents and Oil red O staining. The proposed mechanism of inhibition of adipogenesis in the 3T3-L1 cells with ethanol extracts of S. chinensis is down-regulation of transcriptional factors and adipocyte-specific genes such CCAAT/enhancer binding protein ${\alpha}$ ($C/EBP{\alpha}$) and Peroxisome proliferator activated receptor ${\gamma}$ ($PPAR{\gamma}$) in concentration dependent pattern. These results suggest that ethanol extracts of S. chinensis inhibits adipognesis in the 3T3-L1 cells and can be used as a safe and efficient natural substance to manage anti-obesity.

본 연구에서 92종의 한약재로부터 물과 ethanol을 용매추출물에 대하여 HAase의 저해에 의한 항염증 효과를 측정한 결과 물 추출물에서는 E. officinalis(86.8%), T. orientalis(80.8%), C. semen(66.5%), M. azedarach(74.7%), S. pubescen (61.3%), S. chinensis(49.15%) 등이 높게 나타났다. Ethanol 추출물에서는 A. altissima와 S. chinensis 추출물이 90% 이상의 높은 항염증 활성을 나타내었다. 이들 중 물과 에탄올 추출물에서 모두 항염증 활성이 높게 측정된 S. chinensis가 선발되었다. 선별된 삼백초의 유효성분을 보다 효율적으로 추출할 방안을 확립하기 위하여 인체에 유해하지 않은 용매로 물과 ethanol을 선택하여 추출 최적조건을 살펴보았다. Phenolic 성분의 추출을 위한 최적조건은 50% ethanol을 사용하여 12시간 추출이 최적이었다. Phenolic 성분의 추출을 위해서는 ethanol이 물보다 더 효율적이었다. 최적조건에서 추출된 삼백초 추출물의 염증억제 활성은 $100{\sim}250{\mu}g/mL$ phenolic 농도로 첨가했을 때 70~80%의 염증 억제 효과를 나타내었으나, $500{\mu}g/mL$ 이상의 농도로 첨가 시 오히려 염증 억제활성이 감소하는 경향을 나타내었다. 삼백초를 초미세 분쇄 하였을 때 추출 수율과 염증억제 활성이 증가하는 것을 확인하였다. 따라서 초미세 분쇄 기술은 한약재로부터 생리활성물질 추출수율의 증가를 목적으로 적용할 수 있는 기술로 개발이 가능할 것으로 판단되었다.
