This study was conducted to investigate the antioxidant activities of extracts from various parts of the pine tree, which is known as a good source of functional food material. While ethanol extraction yields of pine bud and cone were higher than water extraction yields of pine bud and cone, water extraction yield of pine needle was higher than ethanol extraction yield of the pine needle. The content of polyphenols in the pine cone ethanol extract was 5 times higher than that in the pine bud and needle. Further, the content of flavonoids in the pine cone ethanol extract was 8 times higher than that in the pine bud and needle. DPPH radical scavenging effect of the pine cone ethanol extract was 3~5 times higher that of the pine bud and needle extract. Regardless of the extraction solvents, trolox equivalent antioxidant capacity (TEAC) and ferric reducing antioxidant power (FRAP) of the pine cone were stronger than those of the other parts of the pine tree. Taken together, it can be expected that the pine cone can be practically used as an antioxidant substance in food and beauty industries.

Ultraviolet (UV) radiation is associated with the development of extrinsic skin aging. We performed in vivo assays in order to investigate the protective effect of a combination of grapefruit and rosemary extracts (cG&Re) on UVB-induced skin aging. The results indicated that cG&Re displayed elastase inhibitory activity in a dose-dependent manner. Topical application of cG&Re mitigated photo-aging related lesions such as skin erythema and thickening in photo-aged BALB/c mice dorsal skin, by preventing UVB-induced collagen degradation. Immunohistochemical analyses revealed that cG&Re stimulated SIRT-1 expression, and suppressed MMP-1 and $IL-1{\beta}$ expression. It was observed that expression of MMP-1 and -13 mRNA was downregulated in the cG&Re-treated group. Furthermore, cG&Re treatment drastically suppressed protein expression of MMP-1 and regulated the phosphorylation of p-38 kinase. As expected, oral administration of cG&Re resulted in the same SIRT-1, MMP-1, and $IL-1{\beta}$ expression patterns observed upon topical application of cG&Re in the UV-induced mice model. Overall, the current results demonstrated that cG&Re attenuated both the downregulation of MMP-1 expression and up-regulation of SIRT-1 expression, as well as decreased phosphorylation of MAPK in UVB-induced skin ageing mice model, suggesting that cG&Re might be used as an internal food ingredient for beauty-purposes as well as a functional food material.

The newly bred Picnic apple was extracted using water and ethanol for extracting solvent. Each water and ethanol extract showed relatively high phenolic compound of 3.69 and 5.55 mg/g. Each water and ethanol extract of Picnic apple showed 1,1-diphenyl-2-picrylhydrazyl of 88.10 and 88.07%, 2,2'-Azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) of 98.79 and 97.25%, antioxidant protection factor of 2.07 and 2.00 PF and thiobarbituric acid reactive substances showed anti-oxidation effect of 9.69 and 19.83% all at $100{\mu}g/mL$ phenolics concentration. Therefore extract of Picnic apple can be considered as anti-oxidant for anti-aging. The anti-inflammatory effect (hyaluronidase inhibition) of extract of Picnic apple were 4.62% with water extract and 4.39% with ethanol extract both at $200{\mu}g/mL$ phenolics concentration. Both water and ethanol extract showed low ${\alpha}$-amylase inhibition effect but each showed 67.37 and 79.16% of ${\alpha}$-glucosidase inhibition effect at $200{\mu}g/mL$ phenolics concentration. In anti-wrinkle effect, water extract showed each 23.70 and 66.29% in elastase inhibition and collagenase inhibition and ethanol extract showed 64.83 and 65.70% each. These result show high potential for functional food and cosmetic source. Picnic apple was identified to have various functions of anti-oxidation, anti-inflammation, anti-wrinkle effect, and anti-diabetic effect. Therefore, Picnic apple is qualified as a source for new functional cosmetics and functional foods.

Development of synthetic vinegar has been focused on the acidic taste typically caused by acetic acid. Recently, consumer interest in fermented vinegars which contain a variety of valuable nutrients increased growth of the beverage industry. Vinegar beverages made of a variety of foreign fruits such as pineapple, grapefruit, and aloe are being commercialized to meet market needs from female consumers interested in beauty. However, commercialization of traditional fermented vinegars using regional products such as rice has not been successful yet compared to fruit vinegar beverages. Systematic research for development and commercialization of functional value-added traditional vinegars made of regional agricultural products should be performed. In this study, type and manufacturing methods of traditional vinegar were reviewed based on classic literatures.

The objective of this study was to identify beauty food activity of Polygala japonica Houtt., which were widely used as a folk medicinal plant to treat inflammatory diseases. Both hot water and 50% ethanol extract of P. japonica Houtt. were evaluated for their anti-oxidant, whitening, anti-wrinkle and anti-inflammatory effect based on their phenolic concentration. To measure anti-oxidant activity, four experiments were carried out. 1,1-diphenyl-3-picrylhydrazyl, 2,2-azinobis (3-ethylbenzothia-zoline-6-sulfonic acid) and thiobarbituric acid reactive substances all showed more than 80% efficacy in both hot water and 50% ethanol extract of P. japonica Houtt. and likewise antioxidant protection factor value more than 2. To investigate the whitening effect of P. japonica Houtt., the inhibition effect of tyrosinase on hot water and 50% ethanol extract was inhibited by 12.46 and 22.10%, respectively. To examine the anti-wrinkle effect, the inhibition effect of elastase and collagenase on hot water and 50% ethanol extract were inhibited by 28.28, 58.36% and 59.73, 78.90% respectively. To investigate the anti-inflammatory effect and moisturizing effect by hyaluronidase inhibitory effect, hot water and 50% ethanol extract were 35.65 and 86.80%, respectively. The result of all the above experiments show values at a concentration of $200{\mu}g/mL$, and based on these experimental results, P. japonica Houtt. can be expected as a functional material in beauty foods.

The immature fruit of Rubus coreanus Miquel (bokbunja in Korean) is mainly consumed as a fruit wine due to its sour taste and low sugar content. The lees (LBW) remaining after the production of bokbunja wine are discarded as they have no specific usage. The aim of this study was to develop high-value-added biomaterials for functional foods and beauty/health products by investigating the anti-microbial, anti-oxidant, and anti-thrombosis activities of LBW using ethanol and hot water extracts and their subsequent organic solvent fractions. The ethyl acetate (EA) fraction of LBW extracts has a high polyphenol content (413–459 mg/g), and showed strong anti-microbial activity against gram-positive bacteria. The EA fraction also showed excellent radical-scavenging activity against DPPH anion, ABTS cation, and nitrite, with strong reducing power. The polyphenol-enriched EA fraction strongly inhibited thrombin, prothrombin, and blood coagulation factors. The butanol fraction showed a specific inhibition of coagulation factors, as measured in activated partial thromboplastin time assay, which is linked to intrinsic blood coagulation. The butanol fraction also showed strong inhibition of platelet aggregation, at levels comparable to aspirin. The residue of the hot-water extract, which is produced by sequential solvent fractionation of the LBW extract, showed superior inhibition against platelet aggregation when compared to aspirin. Our results suggest that the LBW, which are currently discarded, are a promising source of novel functional foods and beauty/health products.
