Aloe gel layer is well known as raw materials of medicines and cosmetics due to their antioxidant and anti-inflammatory properties. In aloe gel extracting process, the outer part of the leaf was removed. It contains high quality of fiber and many nutrients. However, this part is thrown away and generally used as fertilizer. The purpose of this research was to examine the important nutrient of Aloe saponaria. Moreover, the feasibility of using aloe as a dietary supplement by feeding fermentation treatment of aloe was investigated. To do this, the aloe leaf was divided into several parts including leaf skin, bottom of the leaf, tip of the leaf, middle of the leaf, and leaf flesh. Then the saponin content were analyzed from each part. The extraction method was used to clarify the saponin content. The aloe then fermented to improve it benefit. The fermented Aloe then given as dietary food to group of pig. Finally, the appropriate feed level was determined and the pork meat quality was analyzed. The extraction of saponin shows that the highest concentration of saponin located on the skin of the leaf. The feeding experiment shows that there is no significant difference in pig growth without aloe dietary food and groups with aloe as dietary food. It was conclude that fermented aloe can replace the pigs normal feeder as an alternative feeding solution.

Anti-oxidative and anti-inflammatory activities of Cotoneaster horizontalis Decne ethanol extract (CHEE) were evaluated. CHEE possessed a potent scavenging activity against 1,1-diphenyl-2-picryl hydrazyl, which was similar to the activity of ascorbic acid which was used as a positive control. CHEE also effectively suppressed hydrogen peroxide-induced reactive oxygen species on RAW 264.7 cells. Furthermore, CHEE induced the expression of the anti-oxidative enzyme heme oxygenase 1, and its upstream transcription factor, nuclear factor-E2-related factor 2. CHEE inhibited LPS induced nitric oxide (NO) formation as a consequence of inducible NO synthase (iNOS) down regulation. Taken together, these results provide us with an important new insight; that C. horizontalis possesses anti-oxidative and anti-inflammatory activities. Therefore, C. horizontalis may be utilized as a promising material in the field of nutraceuticals.

In this study, to evaluate the anti-oxidative and anti-inflammatory effects of Carpinus pubescens Burkill ethanol extract (CPEE), we performed the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging, reactive oxygen species (ROS) inhibition, and nitric oxide (NO) scavenging assays and an analysis of the related protein expressions. CPEE showed high DPPH radical scavenging activity and effectively increased ROS inhibition activity dose-dependently. Furthermore, CPEE induced the expression of the anti-oxidative enzyme heme oxygenase 1 and its upstream transcription factor, nuclear factor-E2-related factor 2, in RAW 264.7 cells. CPEE was associated with a reduction in NO production, which was induced by lipopolysaccharide treatment in a dose-dependent manner. The expression of inducible nitric oxide synthase (iNOS), an upstream regulator of NO production, was also inhibited. Taken together, these results suggest that CPEE has anti-oxidative and anti-inflammatory activities and could be useful as a potential anti-oxidant and antiinflammatory agent.

This study was designed to evaluate the improvement in exercise endurance by Hovenia dulcis fruit hot water extract (HDWE) for the potential application as a functional food material. The effect was based on the evaluation of the forced-swimming capacity and changes in biochemical parameters in mice. Six-week-old mice were classified into four groups based on a randomized block design: the negative control group, the HDWE 50 mg/kg body weight group, the HDWE 200 mg/kg body weight group, and the 1-octacosanol 50 mg/kg body weight group (n=8 mice per group). The swimming exercise time in the HDWE-50 group was increased at 545±43 sec compared to the control group at 263±28 sec. The HDWE-200 fatigue indicators, lactate acid and ammonia content, decreased to 4.99±0.33 mg/mL and 0.63±0.05 mg/mL, respectively. In addition, the content of glycogen in the liver and muscle tended to increase in the group administered HDWE but was not significant. Likewise, the LDH and glucose contents were increased compared to the control group. The muscle damage indicators ALT (52.7±2.6 U/L) and AST (42.5±5.2 U/L) tended to decrease compared to the control group (76.4±10.2 U/L).

Paeoniae Radix Rubra is a preparation consisting of desiccated roots of Paeonia lactiflora PALL (belonging to Ranunculaceae). Paeoniae Radix Rubra is used as a medicinal herb in Asian countries to treat many diseases. Ethanol- or water-based extracts of Paeoniae Radix Rubra were prepared and tested on RAW 264.7 cells, a murine macrophage cell line. The expression of some pro-inflammatory proteins, including inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), extracellular signal-regulated kinase 1/2 (ERK1/2) and phosphorylated ERK1/2 was detected by Western blot analyses, while PGE2 expression was quantified by ELISA. Both the water and ethanol extracts of Paeoniae Radix Rubra suppressed LPS-induced nitric oxide (NO) production and exhibited cell toxicity in accordance with increased NO production. Also, both extracts reduced the expression of COX-2 and iNOS, and inhibited phosphorylation of ERK1/2 in LPS-stimulated RAW 264.7 cells. Extracts prepared from Paeoniae Radix Rubra contain anti-inflammatory agents that inhibit the iNOS and MAPK pathways.
