For the purpose of developing natural antioxidant, the antioxidative and antimicrobial activities of phenolics isolated from spices were determined. The total phenolics contents of spices were more than 20 mg/g in water and 60% ethanol extracts of all spice, oregano and sage. Electron donating ability assay showed high inhibition rate in water extracts of all spice, nutmeg, white pepper, oregano and sage and 60% ethanol extracts of oregano and nutmeg. Antioxidant protection factor (PF) was higher than 1.2 in 60% ethanol extracts of sage, all spice and oregano and water extracts of sage. The 2,2'-azinobis-3-ethylbenzothiazoline-6-sulfonic acid radical decolorization (ABTS) was inhibited by more than 90% by water and 60% ethanol extracts of all spice and oregano. TBARS (thiobarbituric acid reactive substances) were $0.7{\mu}M$ in the control and $0.2{\mu}M$ in water and 60% ethanol extracts the each spices. The water extracts of each spices did not have antimicrobial activity against H. pylori; however, the 60% ethanol extracts from oregano revealed the high antimicrobial activity as clear zone of 10 mm and inhibition rate of 77.2% with $200{\mu}g/mL$ of phenolics content. The result suggests that spices extract may be useful as potential sources of anti-Helicobacter pylori, antioxidant.

Physiological activities in mulberry leaf and fruit were examined. Electron-donating ability (EDA), tyrosinase activity, SOD-like action (SOD), angiotensin I-converting enzyme-(ACE) inhibitory activity,and nitrite-scavenging ability of mulberry leaf and fruitextracted with water, with 50% (v/v) or with 100% ethanol, were measured. The EDA of mulberry leaf and fruit extracted with water or 50% (v/v) ethanol were greater (by 65.72-81.30%) than that with the 100% ethanol extract, whereas the activities of both former extracts were lower than those with 1.0% and 0.1% (both w/v) L-ascorbate solutions. The SOD-like activities of water, 50% (v/v) and 100% ethanol extracts of all samples were 24.13.26.80% lower than those of 1.0% and 0.1% (both w/v) L-ascorbate solutions. Nitrite-scavenging activity at pH 1.2 was observed in all extracts. The results further our understanding of the physiological activities of mulberry leaf and fruit extracts.

Myrrh, Angelicae Radix, and Schisandrae Fructus have been used to treat diverse diseases including neurological disorder in the traditional Korean medicine. In the present study, we investigated the ameliorating effects of HPM-1, a combined extract of Myrrh, Angelicae Radix and Schisandrae Fructus, on scopolamine-induced memory impairments in mice. First, we assessed HPM-1, HPM-2 and HPM-3, in which Myrrh was extracted with water, 30% ethanol, and 30% ethanol/3% vinegar, respectively. The oral administration of HPM-1, HPM-2, or HPM-3 significantly reversed scopolamine-induced reduction of spontaneous alternation in the Y-maze task. In the passive avoidance task, HPM-1 or HPM-3 restored the decreased latency time of the retention trial by scopolamine treatment, but in terms of efficacy, HPM-1 showed more beneficial effects than HPM-3. In addition, HPM-1 administration reversed scopolamine-induced reduction of spontaneous alternation in the Y-maze task and scopolamine-decreased latency time in the passive avoidance in a dose-dependent manner. These results suggest that HPM-1 has the therapeutic potential in memory impairments.

The anti-metastatic activity of water extract of Samguikoeuitang (WSGKE) consisting of Ginseng Radix, Angelicae Radix, Sophora flavescens and Coicis Semenwas examined. Ethanol extract of Samguikoeuitang (ESGKE) showed significant cytotoxicity against colon 26-M3.1 carcinoma cells, while WSGEK did not. However, WSGKE significantly increased the production of IL-6 and IL-12 in thioglycollate-induced macrophages from Balb/c mice, whereas ESGKE did not. WSGKE significantly increased natural killer (NK) cell cytotoxicity against effecter YAC-1 cells in an Effecter cells/Target ratio dependent manner. Also, WSGKE significantly suppressed lung metastasis after i.v. injection of colon26-M3.1 carcinoma cells. Inhibitory effect of WSGKE on lung metastasis totally abolished in NK cells-deficient mice by treatment with anti-asialo GM1 serum. In addition, the combination treatment of cisplatin and WSGKE (100 ${\mu}g$/mouse) prolonged the lifespan of mice inoculated by colon26-M3.1 cell. These findings suggest that WSGKE can inhibit lung metastasis and prolong life span via immunological enhancement as a Biological Response Modifier.

The bioactive compounds and antioxidant activity of aronia leaves at different stages of maturity were identified and evaluated. Young and old leaves were approximately 2 months of age and 4 months of age, respectively. The young leaves contained more polyphenols and flavonoids than the old leaves. Three phenolic compounds (i.e., chlorogenic acid, p-coumaric acid, and rutin) were detected by HPLC. Antioxidant activity was measured using 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical, 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radical, and superoxide anion radical scavenging assays. The reducing power of aronia leaf extracts increased in a concentration-dependent manner ($0{\sim}100{\mu}g/mL$). The antioxidant activity of the 80% ethanol extract was greater than that of distilled water extract. The high phenolic compound content indicated that these compounds contribute to antioxidant activity. The overall results indicate that aronia leaves contain bioactive compounds, and that younger aronia leaves may be more favorable for extracting antioxidative ingredients because they contain more polyphenols.

In this study, we analyze the antioxidant and anti-inflammatory activities of various extracts of Cryptoporus volvatus. Three extracts were prepared using hot-water, 70% ethanol, and 70% methanol. Compared to the hot-water and 70% methanol extracts, the 70% C. volvatus ethanol extracts showed significantly higher DPPH radical scavenging activities (76.1%), nitrite scavenging activities (29.5%), and total polyphenol content (9.17 mg GAE/g). The DPPH radical and nitrite scavenging activities of C. volvatus both correlated significantly with the total polyphenol content. The Pearson's correlation coefficient of DPPH radical and nitrite scavenging activities with total polyphenol content were r = 0.744 (p<0.05) and r = 0.921 (p<0.01), respectively. To test their anti-inflammatory effects, nitric oxide production and cell viability were measured by performing nitric oxide (NO) and MTT assays on lipopolysaccharide-treated RAW 264.7 cells. The NO production levels of the 70% ethanol extract-treated cells were slightly lower than those of the others. In our MTT assay, the hot-water extracts showed higher cell viabilities (81.4%) than those of 70% ethanol and 70% methanol extracts. The ${\beta}$-glucan content of C. volvatus was 37.8%. From the results of this study, it is suggested that C. volvatus, an easily accessible wild mushroom, has potential to be used in the development of medicines, cosmetics, and functional health foods.

This study was carried out to determine the antioxidative, antimutagenic, and anticancer effects of Rhodiola sachalinensis root using 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical donating method, Ames test and cytotoxicity, respectively. Rhodiola sachalinenis root were extracted with ethanol and then further fractionated to n-hexane, chloroform, ethyl acetate (EtOAc), butanol and water, stepwise. Among five fractions, the Etohc fractions showed the highest electron donating activities (14.3 $\mu$g/mL). The inhibition rate of ethanol extract (200$\mu$g/plate) of Rhodiola sachalinensis root in the S. typhimurium TA100 strain showed 89.1% inhibition against the mutagenesis induced by MNNG. In addition, the suppression of EtOAc fractions with same concentration of Rhodiola sachalinensis root in the S. typhimurium TA98 and TAI00 strains showed 89.7% and 91.5% inhibition against 4NQO, respectively. The suppressions under the same condition against B($\alpha$)P and Trp-P-1 in the TA98 and TA100 strains were 94.2% and 95.7%, and 92.3% and 93.8%, respectively. The cytotoxic effects of Rhodiola sachalinensis root against the cell lines with human lung carcinoma (A549), human hepatocellular carcinoma (HepG2), human gastric carcinoma (AGS) and human breast adenocarcinoma (MCF-7) were inhibited with the increase of the extract concentration. The treatment of 1.0 mg/mL Rhodiola sachalinensis root of EtOAc fraction showed strong cytotoxicities of 90.5%, 81.5%, 92.2% and 82.6% against A549, HepG2, AGS and MCF-7, respectively.
