In this study, cosmetic materials were developed using a new method of making juice through the fermentation of raw natural materials with microorganisms in order to supplement the advantages and disadvantages of an organic solvent extraction method and a microbial fermentation method. The natural products were selected from two colors (red, green) of paprika known to be rich in various colors and vitamins. The microorganisms used for fermentation were fermented by inoculating paprika with lactic acid bacteria (Lactobacillus plantarum) having sugar-hydrolyzed ability. First, we investigated the changes of physiologically active substances of two kinds of paprika juice and two kinds of fermented paprika juice. Total phenols content and total flavonoids content were higher in the fermented paprika juice than in the paprika juice, and especially in the fermented red paprika juice. Free radical scavenging effect and lipid peroxidation inhibitory effect were also showed an excellent antioxidative effect on paprika fermented juice, among which the effect of red paprika fermentation juice was the highest. The expression of MMP-1 in fermented red paprika juice with high antioxidant activity was inhibited by concentration-dependent expression of MMP-1 mRNA and MMP-1 protein. In the glycation experiments with aging, the anti-glycation effect of fermented paprika juice was highly inhibited by the production of advanced glycation end-products (AGEs), which was closely related to the antioxidant effect. In addition, the activity of senescence-associated ${\beta}$-galactosidase (SA-${\beta}$-gal), an indicator of cell senescence, was measured using human dermal fibroblast (HDF). The results showed that the cell senescence was inhibited when the cells were treated with fermented paprika juice. In conclusion, fermented paprika juice using lactic acid bacteria showed better antioxidative and anti-aging effects than paprika juice. Among them, fermented red paprika juice has the best antioxidant and anti-aging effect and can be applied as natural new material of antioxidant and anti-aging.

To develop the health/functional food materials, we investigated the cultural condition of mycelial growth on the solid state fermentation using the brown rise, Acanthopanax sp. and Artemisia sp., and also evaluated inhibitory activity of angiotensin converting enzyme (ACE) of hot water extracts from cultured media of Pleurotus eryngii. As the amount of Acanthopanax nnd Artemisia In the cultural media increased, the mycelial growth rate decreased. Especially, addition of Aeantopanax showed marked effect than Artemisia. Moisture contents in three kinds of cultured media were in the range of $10.9{\sim}12.0%$. Crude protein fat and crude fiber content were the highest value in cultured brown rice medium, whereas the mineral contents (Ca, K and P) were higher in the Acanthopanax supplemented (5%) medium than the other media, The extraction yield of the Artemisia supplemented (5%) medium was the highest value of 4.80%, and the pH of hot water extract from cultured brown rice medium showed the lowest value of 6.1. Lightness (L) values in three kinds of extracts from cultured media were in the range of $85.8{\sim}87.1$. Redness (a) value was the highest In the brown rice and Acanthopanax supplemented media, however cultured Artemisia supplemented medium showed the highest value in yellowness (b). In comparison of sugar components analyzed by the thin layer chromatography with three kinds of samples, two spots were detected to be glucose and maltose, respectively. The ACE inhibitory activity of hot water extract from the cultured Acanthopanax supplemented medium showed the highest value at the concentration of $0.2{\sim}1.0\;mg/ml$. These results suggest that the Pleurotus eryngii grew in natural media using brown rice and Acanthopanax can be supplemented to the brown rice medium to enhance its ACE inhibitory activity as health/functional food materials.

This study was conducted to examine the antioxidant activities and physiological activities of mixture extracts (Liriope platyphylla, Schizandra chinensis and Panax ginseng C.A. Meyer) with different extraction mixing ratios (MEC, 2:1:1; ME1, 1:2:1; ME2, 1:1:2; ME3, 1.34:1.33:1.33). The yield of extracts ranged from 25.33 to 33.87%. The total polyphenol and total flavonoid contents of ME1 extracts were 1.01 g/100 g, 0.07 g/100 g, respectively. The total sugar contents of MEC extract was 22.83 g/100 g, respectively. The DPPH and ABTS radical scavenging activities of ME1 extracts at $1,000{\mu}g/mL$ were 26.79% and 21.08%. The superoxide radical scavenging and ferric-reducing antioxidant power of ME1 extracts at $1,000{\mu}g/mL$ were 67.83% and $295.47{\mu}M$, respectively. The functionalities of extracts were investigated with L-132 and RAW264.7 cell lines. The extracts on different mixing ratios did not show the toxicity on L-132 and RAW264.7 cell line in $100-2,500{\mu}g/mL$. The ME1 extract of $1,000{\mu}g/mL$ performed better than other extracts protective effects against oxidative stess in L-132 cells (81.22%) and the ME2 extract at $1,000{\mu}g/mL$ decreased nitric oxide production by $7.48{\mu}M$ which was more potent than other extracts. There results suggest that the ME1 extracts may be a useful functional food material in the food industry.
