Sanguisorbae radix (SR) from Sanguisorba officinalis L. (Losaceae) is widely used in Korea and China due to its various pharmacological activity. The present study aims to investigate the effect of the methanol extract of SR on amyloid ${\beta}$ Protein(25-35) $(A{\beta}\;(25-35))$, a synthetic 25-35 amyloid peptide, -induced neurotoxicity using cultured rat cortical neurons. SR, over a concentration range of $10-50\;{\mu}g/ml$, inhibited the $A{\beta}$ (25-35) $(10\;{\mu}M)-induced$ neuronal cell death, as assessed by a 3-[4,5-dimethylthiazole-2-yl]-2,5-diphenyl-tetrazolium bromide (MTT) assay and the number of apoptotic nuclei, evidenced by Hoechst 33342 staining. Pretreatment of SR $(50\;{\mu}g/ml)$ inhibited $10\;{\mu}M\;A{\beta}$ (25-35)-induced} elevation of cytosolic calcium concentration $([Ca^{2+}]c)$, which was measured by a fluorescent dye, fluo-4 AM. SR $(10\;and\;50\;{\mu}g/ml)$ inhibited glutamate release into medium induced by $10\;{\mu}M\;A{\beta}(25-35)$, which was measured by HPLC, and generation of reactive oxygen species. These results suggest that SR prevents $A{\beta}$ (25-35)-induced neuronal cell damage in vitro.

In this study, the various physiological and anti-inflammatory activities of Sanguisorba officinalis L. roots (SR) were assessed for potential use as functional cosmetic materials. As a result of measuring electron-donating abilities to determine the antioxidant ability of SR extract, activity increased as the concentration increased, showing an excellent antioxidant capacity of 93.8% at a 1,000 ㎍/ml concentration. Further, the antioxidant power of SR extract, which was determined using an ABTS⁺ assay measurement, was more than 99% at concentrations of 50 ㎍/ml or more, while the tyrosinase inhibition rate was 37.7% at the highest concentration of 1,000 ㎍/ml. Consequently, the elastase and collagenase inhibition of SR extract measured 84.9% and 90.3%, respectively, at a 1,000-㎍/ml concentration. As a result of confirming the survival rate of Raw 264.7 cells, the cell survival rate was determined to be 80% or more below a 100 ㎍/ml concentration, and subsequent cell-related experiments were conducted at concentrations below 100 ㎍/ml. Furthermore, after applying a NO assay to identify anti-inflammatory activity, it was confirmed that SR extract had an inhibitory rate of 50.8% at a concentration of 500 ㎍/ml, and it was excellent at suppressing the inflammatory expression. As a result of verifying protein expression by treating SR extract in Raw 264.7 cells, it was confirmed that expression was inhibited concentrated in all factors. Therefore, it is judged that SR can be used as a functional cosmetic material with antioxidant, whitening, and wrinkle-improving physiological effects and anti-inflammatory activities.

In this study, the optimal conditions for phenolic-compound extraction from medicinal plants were found to be 24 h and about 50% ethanol. The electron-donating scavenging activities (DPPH), ABTS radical-cation decolorization (ABTS), antioxidant protection factor (PF), and thiobarbituric acid reaction substance (TBAR) were measured to determine the antioxidant activities of the extracts of Sanguisorba officinalis Linn., Citrus unshiu Markovich, Melia azedarach L., Asparagus cochinchinensis Merr., Citrus unshiu S., Polygonum aviculare L., and Leonurus sibiricus L. The total phenolic contents of the extracts of medical plants were determined to be 0.45-3.00 mg/g in the water extracts and 0.33-3.15 mg/g in the 50% ethanol extracts. The electron-donating abilities (EDA) of the water and ethanol extracts were both above 85% at the $50{\mu}g/ml$ concentration. The ABTS radical-cation decolorization was above 80% at the $100{\mu}g/ml$ concentration in all the extracts of various medicinal plants. The antioxidant protection factor (PF) of the Melia azedarach L. extracts was found to be $1.65{\pm}0.40$ PF in the water extracts at the $100{\mu}g/ml$ concentration, and was higher than those of the other medicinal-plant extracts. The TBAR inhibition rates of all the medicinal-plant extracts, except Asparagus cochinchinensis Merr., were above 85% at the $100{\mu}g/ml$ concentration. These results confirmed that the various oriental medicinal plants (Sanguisorba officinalis Linn., Citrus unshiu Markovich, Melia azedarach L., Asparagus cochinchinensis Merr., Citrus unshiu S., Polygonum aviculare L., and Leonurus sibiricus L.) that were included in this study are useful functional-food sources.

The objective of this study was to determine the radical scavenging activity, total phenolic content, antimicrobial activity, minimum inhibitory concentration (MIC) of ethanol extracts of 32 medical plant species that have been commonly used in medicinal plants. Total phenolic index of T. chebula exhibited the highest value (498.01㎎/g), followed by R. coreanus miquel (400.33㎎/g), Sanguisorba officinalis (368.25㎎/g), P. thumbergiana (259.74㎎/g) and Eugenia aromaticum (229.38㎎/g). Radical scavenging activity for the DPPH radical was highest in T. chebula (40.91%, p<0.01), followed by C. sappan (36.50%), S. officinalis (32.92%), R. coreanus miquel (26.54%) and P. thumbergiana (24.50%). The extracts from T. chebula, R. coreanus muquel, C. sappan, E. aromaticum, S. officinalis and C. japonica possessed outstanding antimicrobial activity against Escherichia coli, Salmonella Typhimurium, Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus subtilis and Lactobacillus plantarum. MIC was determined on those extracts that showed high efficacy against the test organisms. The most potent MIC values were seen for T. chebula extract against P. aeruginosa, S. aurusa, E. coli, B. subtilis, L. plantarum and S. Typhimurium at 7.8, 7.8, 15.6, 7.8, 125 and 31.2㎍/mL, respectivley. Furthermore, the total phenolic content and radical scavenging activity were very closely correlated for all samples (r=0.78). The coefficient correlations between total phenolic index and antimicrobial activity were 0.91 (E. coli), 0.91 (B. subtillis), 0.79 (P. aeruginosa), 0.79 (S. Typhimurium) and 0.70 (L. plantarum).

Colorectal cancer is a major health problem in industrialized countries. Ziyuglycoside II ($3{\beta}-3-{\alpha}$-1- arabinopyranosyloxy-19-hydroxyurs-12-en-28-oicacid), a triterpenoid saponin isolated from the roots of Sanguisorba officinalis L., possesses antioxidant, antiangiogenic, and anticancer properties. However, the therapeutic function of ziyuglycoside II in colitis-associated colorectal carcinogenesis is undefined. In the present study, the effect of ziyuglycoside II on colitis-associated colon cancer induced in mice using azoxymethane (AOM)/dextran sulfate sodium (DSS) was explored. The AOM model recapitulates many features of human colon cancer, but it lacks an inflammatory component. DSS induces colitis and promotes AOM-induced colon cancer in mice. BALB/c mice were injected with AOM and administered 2% DSS in drinking water. The mice were given ziyuglycoside II (1 or 5 mg/kg) orally three times per week, and colonic tissue was collected at 64 days. Administration of ziyuglycoside II markedly diminished the formation of colonic tumors. Western blot and immunohistological analyses showed that ziyuglycoside II noticeably decreased nuclear factor kappa-B-positive cells and levels of inflammation-related proteins, such as inducible nitric oxide synthase, cyclooxygenase-2, tumor necrosis factor-${\alpha}$, and interleukin-6 in colon tissue. It also prompted apoptosis. Ziyuglycoside II treatment augmented cleaved forms of caspase-3, caspase-7, and poly (ADP-ribose) polymerase in colonic tissues. In conclusion, ziyuglycoside II could defend against colitis-associated tumorigenesis in mice by inhibiting inflammation and inducing apoptosis. This shows a promising chemopreventive potential for its use in colitis-associated colon cancer.

It is thought that highly reactive oxygen radicals generated at the ischemia-reperfusion in case of strokes play an important role in damaging the brain. We examined the neuroprotective effects from the several medicinal herbs in the transient ischemic rat model and compared their effects with the free radical scavenging activities. Transient ischemia was induced by intraluminal occusion of the right middle cerebral artety for 120 min and reperfusion was continued for 22 h in rats. The free radical scavenging properties of medicinal herbs were examined in vitro by determination of the interaction with the 1,l-diphenyl-2-picrylhydrazyl (DPPH) stable free radical. Aqueous extracts of 11 medicinal herbs (200 mg/kg) were orally administered, promptly prior to reperfusion and 2 h after reperfusion. Total infarction volume in the ipsilateral hemisphere of ischemia reperfusion rats was significantly lowered by the treatment of 7 medicinal herbs (Sophora flavescens, Lycopus lucidus, Sanguisorba officinalis, Caesalpinia sappan, Albizia julibrissin, Rubia akane, Psoralea corylifolia, Prunella vulgaris). However, all of these medicinal herbs did not show antioxidative activities. These results suggest that neuroprotective effects of several drugs are not always correlated with their antioxidative properties.

Three different oriental natural plants (Angelicae Dahuricae Radix, Sanguisorba Officinalis L, Euonymus alatus) were extracted with 70% methanol under refluxing for 4 hr in order to investigate their inhibitory effect on Matrix Metalloproteinase-9 (MMP-9) by a modified gelatin zymography, where only euonymus alatus showed the inhibitory effect on the activity of Matrix MMP-9. The fraction was collected by using the mixture of ethyl acetate and hexane on silica gel column. Seven portions were obtained and three fractions of them (first, third and forth) showed inhibitory effect on the zymography. To verify the effect of these substances on cells, human hepatoma, Hep3B cells as a cancer model, and Chang liver cells as a normal model were selected. In order to examine the cell viability, $1{\mu}g/mL$ of each extract was treated on cells. Most of the methanol soluble fractions showed negligible toxicity on human liver cell line.
