The objective of this study is to investigate the quality characteristics of Yanggaeng by using the functional properties of Glechoma hederacea (GH). Sample was dried at $50^{\circ}C$ dry oven. The results of the study were as follows : The Phenolic compounds of GH was $12.99{\pm}0.3mg/g$ in water extract (GHWE), $3.14{\pm}0.07mg/g$ in 70% ethanol extract (GHEE). The antioxidant activity of GH was determined in various phenolic concentrations at $50-200{\mu}g/mL$. DPPH activities of GHWE and GHEE were 77.16-78.24% and 73.04-77.00%, respectively. The ABTS were 84.35-99.75% and 83.74-99.55%. The anti-oxidant protection factor (PF) were 1.54-1.62 PF and 1.62-2.09 PF and TBARS were 42.93-94.09% and 91.05-95.19%, respectively. Tyrosinase inhibitory activity of GHEE increased concentration dependently. Hyaluronidase inhibition activity of GHEE and GHWE, showing that there were increasing pattern depending on the increases in the phenolics concentration of GH. In texture, Hardness and springiness were significantly different in the control and 2% groups, but cohesiveness and chewiness did not show any significant difference. In color, L value decreased in proportion to concentration, and a and b values did not change. Sensory characteristics showed that the 1% group had the highest score and the 2% group had the lowest score. Thus, when the GHP Yanggaeng was prepared, in consideration of its sensory characteristics, and at appropriate concentration on below 1%.
Pinus densiflora Sieb. et Zucc. (P. densiflora) contains several phenolic compounds that exhibit biological activities, such as antimicrobial, antioxidant, and antihypertensive effects. However, the anti-inflammatory effect of P. densiflora on skin has rarely been reported. Malassezia furfur (M. furfur) is a commensal microbe that induces skin inflammation and is associated with several chronic disorders, such as dandruff, seborrheic dermatitis, papillomatosis, and sepsis. The aim of our study was to identify the anti-inflammatory effects of P. densiflora needle extracts on skin health subjected to M. furfur-induced inflammation. The methanolic extract of the pine needles was partitioned into n-hexane, EtOAc, n-BuOH, and water layers. We measured the anti-inflammatory effects (in macrophages) as well as the antioxidant, antifungal, and tyrosinase inhibitory activity of each of these layers. The antioxidant activity of the individual layers was in the order EtOAc layer > n-BuOH layer > water layer. Only the n-BuOH, EtOAc, and n-hexane layers showed antifungal activity. Additionally, all the layers possessed tyrosinase inhibition activity similar to that of ascorbic acid, which is used as a commercial control. The EtOAc layer was not cytotoxic toward the RAW 264.7 cell line. Interleukin 1 beta and tumor necrosis factor (TNF)-α expression levels in M. furfur-stimulated RAW 264.7 cells treated with the EtOAc layer were decreased markedly compared to those in cells treated with the other layers. Taken together, we believe that the needle extracts of P. densiflora have potential application as alternative anti-inflammatory agents or cosmetic material for skin health improvement.
The purpose of this study was to investigate the biological activities of an aqueous extract of Angelica gigas (Ag) fermented by Saccharomyces cerevisiae (Sc). First, the soluble solids of the F/3 group, in which the Ag was fermented by Sc for 3 days, decreased from $1^{\circ}Bx$ to $0.9^{\circ}Bx$. On the other hand, the pH increased with the number of days of fermentation. The result of a TLC experiment confirmed that it gradually decomposed into a low-molecular weight sugar form upon fermentation. The total phenolic compounds and flavonoid contents were higher in the fermented group than in the non-fermented group. K and Ca contents were increased by fermentation in the following order: F/3, NF, and F/0 groups. Decursin and decursinol angelate contents were highest in the F/3 group. The DPPH (${\alpha}$, ${\alpha}{\prime}$-diphenyl-${\beta}$-picrylhydrazyl) radical scavenging activity of the NF, F/0, and F/3 groups were 41.89%, 39.51%, and 60.26%, respectively. The inhibition activities of tyrosinase and lipoxygenase were stronger in the F/3 group than in the NF group. This experiment showed that the fermentation of Ag Nakai can lead to an increase in its antioxidant ability, physiological activity, whitening and anti-inflammatory effects. Thus, this oriental herbal medicine can be developed into a functional material that can be utilized in the development of cosmetic products in future.

The purpose of this study was to confirm the skin whitening and UV absorption effects of bioconverted Beta vulagaris (BBE) using Lactiplantibacillus plantarum SM4, and the effects were evaluated by measuring total polyphenol content (TPC), total flavonoid content (TFC), radical elimination activity (RSA), and tyrosinase activity inhibition (TAI). TPC and TFC of BBE were 25.0 mg GAE/g DM and 8.05 mg QE/g DM, which were 1.3 and 1.1 times higher than hot-water extract (HWE) respectively. RSA, an indicator of antioxidant activity, and TAI, an indicator of skin-whitening effect, were 36.8%, and 68.6%, respectively, 1.1 and 1.2 times higher than that of HWE. UVA and UVB absorption of BBE were 21.4 and 87.6%, which was 1.4 and 1.7 times higher than that of HWE respectively. When main substances of BBE were analyzed using LC-MS/MS, kaempferol and isorhamnetin, a type of polyphenols known to have high antioxidant and skin-whitening effects, were identified. As a results, BBE is expected to be used as a functional cosmetic material as it has excellent antioxidant, skin whitening, and UV absorption properties.

Inhibition of the early N-glycosylation process in the endoplasmic reticulum prevents the activation of tyrosinase, a key enzyme for melanin biosynthesis. This work aims at evaluating the increased activity of N-glycosylation inhibitors in vitro b, employing a nano-sized pH-sensitive liposome as a delivery carrier. Melexsome, a pH-sensitive nano carrier loaded with glycosylation inhibitos, was prepared by the hydration method with phospholipids and cholresterol-based amphiphiles. Inhibitory effects of Melexsome on the N-glycosylation process were evaluated by EndoH & PNGaseF digestion and the western blotting. Melanin synthesis was also monitored after treatment with Melexsome Interestingly, Melexsome effectively increased the efficacy of N-glycosylation inhibitors. Melexsome was also much more efficiently translocated into the cytoplasm as observed in CLSM. These results demonstrated that the amphiphilic lipid-based pH-sensitive nano-carriers could be, used as an efficient delivery system for N-glycosylation inhibitor to enhance the effects of skin whitening cosmetics.

Saposhnikovia has been used as a traditional medicinal herb in Asia because of the reported anti-inflammatory, anti-allergic rhinitis, pro-whitening, anti-atopy, anti-allergy, and anti-dermatopathy effects of the phytochemical compounds it contains. In this study, we investigated the antioxidant effects of a Saposhnikovia extract after fermentation by Lactobacillus plantarum BHN-LAB 33. Saposhnikovia powder was inoculated with L. plantarum BHN-LAB 33 and fermented at $37^{\circ}C$ for 72 hr. After fermentation, the total polyphenol content of the Saposhnikovia extract increased by about 14%, and the total flavonoid content increased by about 9%. The superoxide dismutase-like activities, DPPH radical scavenging, ABTS radical scavenging, reducing power activity, and tyrosinase inhibition activity also increased after fermentation by approximately 70%, 80%, 45%, 39%, and 44%, respectively. The results confirmed that fermentation of a Saposhnikovia extract by L. plantarum BHN-LAB 33 is an effective way to increase the antioxidant effects of the extract. The bioconversion process investigated in this study may have the potential to produce phytochemical-enriched natural antioxidant agents with high added value from Saposhnikovia matrices. These results can also be applied to the development of improved foods and cosmetic materials.

The purpose of this study was to evaluate the functionality of ethanol extract of Aster scaber by analyzing anti-oxidant components and anti-oxidant activities, which was grown in wild and culture field. The yields of Aster scaber ethanol extracts were high after blanching treatment. The polyphenol content of dried Aster scaber grown in wild was 35.59 mg/g, which was higher than that of Aster scaber grown in culture field. The electron donating ability in all Aster scaber extracts were increased with increase in extract concentration, and the electron donating ability was the highest in extracts of the dried Aster scaber after blanching. The SOD-like activity of Aster scaber was the highest in its extract grown in wild field. In addition, the SOD-like activities of extracts of the dired Aster scaber after blanching were highest among the extracts of cultivated Aster scaber. The nitrite scavenging ability of extracts was increased at pH 1.2, and those was the highest in wild fresh Aster scaber. The inhibition effects on xanthine oxidase and tyrosinase were increased with increase in extract concentration, and the inhibition effects of extracts of Aster scaber in wild field were higher than those grown in culture field. Therefore, the consumption of Aster scaber would provide beneficiary effects due to its antioxidant activities and prevention of aging. The development of various processed food using Aster scaber will promote the consumption and its values.
This study was undertaken to investigate the effect of an ethanol extract of Elaeagnus umbellata leaves (EUL-EE) on skin-related biological activities. Previously, we have reported that gallic acid was the major phenolic compound in EUL-EE through quantitative analysis and that EUL-EE had an inhibitory effect against the proliferation of liver cancer HepG2 cells. In the present study, the inhibitory effects of EUL-EE on melanin production and tyrosinase activity in ${\alpha}$-melanocyte-stimulated hormone-stimulated B16-F0 cells were determined to assess the effects of EUL-EE on skin whitening. The anti-wrinkle effect using UVB-irradiated CCD-986sk cells was examined by the expression of type I procollagen and metalloproteinase (MMP)-1 release. The EUL-EE significantly decreased intracellular melanin production (33.0% inhibition at $100{\mu}g/ml$) when compared with untreated B16-F0 cells. Tyrosinase activities in the stimulated B16-F0 cells were also decreased by EUL-EE (47.8% inhibition at $100{\mu}g/ml$). The EUL-EE also dose-dependently increased the production of type I procollagen (up to 1.74-fold at $250{\mu}g/ml$) in CCD-986sk cells when compared with UVB-irradiated controls. EUL-EE showed no cytotoxicity at concentrations up to $500{\mu}g/ml$. In addition, EUL-EE at $10-500{\mu}g/ml$ inhibited the release of MMP-1 to the medium from UVB-irradiated CCD-986sk cells. Taken together, these observations indicate that EUL-EE has high potential for use as inner beauty and cosmetic materials due to its whitening and anti-wrinkle effects.
This study was conducted in order to analyze the polyphenol contents and antioxidant activities of hot-water extracts of Aster scaber in the wild field and cultivated field, and through the drying methods for the comparison on the quality characteristics of Aster scaber, according to cultivation and drying methods, and the development of functional materials. The extraction yield was higher in the Aster scaber cultivated field than those of the Aster scaber in the wild field, and high from the dried Aster scaber. The total polyphenol and flavonoid contents of Aster scaber hot-water extracts from the wild field were higher than those in the cultivated field. The total polyphenol contents were high in the extract of blanched and dried Aster scaber, and the flavonoid content was high in the non-treated Aster scaber. The electron donating ability (EDA) values of Aster scaber hot-water extracts were increased along with the increase of extract concentration, while the EDA of the blanched and dried Aster scaber extracts was higher than the other extracts. Furthermore, the SOD-like activity was increased by the extract concentration, and was high in the extract of the non-treated Aster scaber. The nitrite scavenging ability in pH 1.2 was high in the non-treated, blanched, dried, and natural dried Aster scaber. The xanthine oxidase inhibitory activities were increased through the increase of extract concentrations, and higher in the hot-water extract from Aster scaber in the wild field (WRA) than those in the other extracts. The inhibition of tyrosinase and reduction of power were increased by the increased extract concentration, and high in the extracts of blanched and dried Aster scaber. The reduced power was higher in the Aster scaber hot-water extracts of cultivated field, and was higher in the extracts of blanched and dried Aster scaber than those in the extracts dried through the use of other drying methods. Aster scaber has a high content of polyphenol and flavonoid, and antioxidant activities, which were developed as functional materials.
The objective of this study was to investigate the physiological activities of Aronia melanocarpa extracts on extraction solvents (through hot water extraction, 50% ethanol extraction, and 50% methanol extraction). The yield of 50% ethanol extract, 84.50%, was higher than that of the hot water extract (84.05%) and of the 50% methanol extract (76.20%). The total sugar content of the extraction solvent, 35.56~37.68 g/100 g, did not significantly differ. The total anthocyanin content of the 50% methanol extract, 395.10 mg/100 g, was higher than of 50% ethanol extract (318.61 mg/100 g) and of the hot water extract (252.82 mg/100 g). The anthocyanin composition of the cyanidin-3-galactoside, 364.65 mg/100 g, was higher than that of the cyanidin-3-arabinoside (163.06 mg/100 g) and of the cyanidin-3-glucoside (35.69 mg/100 g) in the 50% methanol extract. The DPPH radical scavenging activities of the 50% ethanol and the 50% methanol extracts at $100-1,000{\mu}g/mL$ were 7.96-70.01%, and 8.90-69.21%, respectively. The superoxide radical scavenging activities of all the extracts improved with an increase in the treatment concentration. The FRAP of the 50% ethanol extract and the 50% methanol extract at $100-1,000{\mu}g/mL$ were $57.14-817.87{\mu}M$ and $67.32-812.78{\mu}M$, respectively. The tyrosinase inhibitory activity of the 50% ethanol extract, 23.03-33.82% ($100-1,000{\mu}g/mL$), was higher than that of the other extracts. The cancer cell growth inhibition activity of the 50% ethanol extract (76.86% at $1,000{\mu}g/mL$) on HeLa cell line was significantly higher than of the hot water and of the 50% methanol extracts. There results suggest that the 50% ethanol extract from Aronia melanocarpa may be a useful for functional food material in the food industry.
