Liquid crystalline phases were formed from acylglutamate; polyglyceryl-10 myristate and glycerine mixture and they were used as a base material for preparing an O/W emulsion. When an oil phase is added into the liquid crystalline phases, it was inserted into the dispersed liquid crystal droplets rather than stayed outside the liquid crystals, which can be known by the fact that the size of liquid crystal droplets increases with the increasing oil phase content. Along with the increase in the droplet size, the complex modulus increases from 100 to 350 pascals and the loss angle decreases from 60 to 24 degrees, from which it can be known that the increase in the internal phase volume results in the increase in the elastic property of oil in liquid crystalline-phases (O/LC). When the water phase was lastly added into the O/LC phase, the emulsification occurred to form a O/W emulsion and the averaged particle size of the O/W emulsion changes from 22.5nm to 538nm with the addition of water phase. The results from the droplet size measurements and stability tests under accelerated conditions such as high temperature show that the obtained O/W emulsion is very consistent with time.

The lyophilization of the solution extracted from 60 percent of acetone applied to persimmon leaves, the compounding process in accordance with the solution's concentration, and the gel filteration through Sephadex G-50 of biologically activated substances obstructing enzyme activity, such as tyrosinase, xanthine oxidase, and angiotesin converting enzyme (ACE) led to the assumption that polyphenol was the compound serving as biologically activated substances obstructing enzyme activity. Xanthine oxidase involved in pruine metabolism oxidizes hypoxanthine to xanthine and xanthine to uric acid. In the continuous study for natural compound, nine flavan-3-ols have been isolated from the persimmon leaves.

Procyanidin B-7-3-O-gallate, (-)-epigallocatechin-(4α→8)-epigallocatechin-(4α→8)-catechin and procyanidin C-1-3'-3'-3'-O-trigallate showed 94%, 90.69%, 80.90% inhibition at 100 (μ)M and inhibited on the angiotensin converting enzyme respectively. Procyanidin B-7-3-O-gallate and procyanidin C-1-3'-3'-3'-O-trigallate showed 66%, 63% inhibition at 100 (μ)M and inhibited on the xanthine oxidase competitively. Procyanidin C-1-3'-3'-3'-O-trigallate showed 70% inhibition at 100 (μ)M and inhibited on the tyrosinase competitively.

In this study, beauty food activities were determined for extracts of Saurus chinensis as functional beauty food. Tyrosinase inhibitory effect was increased as more 4 folds by ultra-fine grind technology than normal grind technology in ethanol extracts from Saurus chinensis. A ultra-fine ground technology was used to increase the extraction yield for bioactive compounds from medicinal plants. Tyrosinase inhibitory activity, which is related to skin-whitening, was confirmed to be 100% for ethanol extracts at 1,000 ppm of phenolics. Anti-wrinkle activity was determined showing 30% of inhibition effect at above 1,000 ppm phenolic concentration. The elastase inhibitory activity of water and ethanol extracts from ultra-fine ground Saurus chinensis showed higher inhibition activity than compared to extracts from normal ground Saurus chinensis. Astringent activity in ethanol extracts was determined showing over 70% at 250 ppm of phenolics. Based on these results, Saurus chinensis extracts can be used as a functional beauty food and cosmetic with whitening, anti-wrinkle and pore contraction effects.

The purpose of this paper is to investigate potential anti-inflammatory and anti-oxidant effects of Tenebrio molitor. Macrophage cell response by outside stimulation leads expression of pro-inflammatory cytokines, such as tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-1β (IL-1β), and trigger expression of genes which are affected by inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), resulting in formation of inflammatory factors like nitric oxide (NO) and Prostaglandin E2 (PGE2). Cell viability was determined by MTT assay. In order to investigate anti-inflammatory agents, the inhibitory effects on the production of lipopolysaccharide (LPS)-induced NO in RAW 264.7 cells were examined. T. Molitor significantly decreased the production of NO in a dose-dependent manner, and also reduced the expression of iNOS, a COX-2 protein. As a result, the levels of protein such as PGE2, iNOS, COX-2 and MARKs were significantly reduced compared to non-treated group in T. Molitor water extract (TDW) treated group. Also, antioxidant effect of T. Molitor were investigated using DPPH, ABTS+ and superoxide anion radical scavenging activity tests in cell-free system. Antioxidant activity of T. molitor was found low in the DPPH radical scavenging test while high in the ABTS+ and superoxide anion radical scavenging activity tests. These results show that TDW could be an effective anti-pro-inflammatory and anti-oxidant agent.
