  • In this study, graviola leaf extracts (GLE) was investigated for the effect of antioxidant, antibacterial, whitening, anti-wrinkle. The antioxidant effect of GLE was measured by an electron donating ability assay. As a result, GLE increased the electron donating ability in a concentration-dependent manner. The antibacterial effect of GLE was found to show the higher antibacterial effect in Methicillin-resistant Staphylococcus aureus CCARM3115 compared with that of ampicillin by a paper disc method. The whitening effect of GLE was also measured by tyrosinase inhibition assay, and it was found that the tyrosinase activity of GLE decreased as the concentration increased. The inhibition activity of tyrosinase involved in hydroxylation reaction which is related to converting L-tyrosine to (DOPA) was higher than that of arbutin's at the concentration ranging from 125 to $250{\mu}g/mL$. In addition, GLE reduced melanin contents of B16-F10 melanoma cells in a dose-dependant manner and decreased to about 76.7% at a concentration of $100{\mu}g/mL$ Regarding wrinkling formation of GLE, an elastase inhibition assay was performed. As a result, GLE and ursolic acid were 10.5% and 56.5%, respectively under the identical concentration. These results suggest that GLE has significant antioxidant and whitening activities, and also may be potentially used as a therapeutic agent for hyperpigmentation treatment as an ingredient of whitening cosmetics.

  • Oxidative stress derived from reactive oxygen species (ROS) is one of the major damaging factors in plants exposed to environmental stress. In order to develop the platform technology to solve the global food and environmental problems in the 21st century, we focus on the understanding of the antioxidative mechanism in plant cells, the development of oxidative stress-inducible antioxidant genes, and the development of transgenic plants with enhanced tolerance to stress. In this report, we describe our recent results on industrial transgenic plants by the gene manipulation of antioxidant enzymes. Transgenic tobacco plants expressing both superoxide dismutase (SOD) and ascorbate peroxidase (APX) in chloroplasts were developed and were evaluated their protection effects against stresses, suggesting that simultaneous overexpression of both SOD and APX in chloroplasts has synergistic effects to overcome the oxidative stress under unfavorable environments. Transgenic tobacco plants expressing a human dehydroascorbate reductase gene in chloroplasts were showed the protection against the oxidative stress in plants. Transgenic cucumber plants expressing high level of SOD in fruits were successfully generated to use the functional cosmetic purpose as a plant bioreactor. In addition, we developed a strong oxidative stress-inducible peroxidase promoter, SWPA2 from sweetpotato (Ipomoea batatas). We anticipate that SWPA2 promoter will be biotechnologically useful for the development of transgenic plants with enhanced tolerance to environmental stress and particularly transgenic cell lines engineered to produce key pharmaceutical proteins.

  • Extrinsic skin aging is characterized by the loss of skin tone and resilience, irregular pigmentation, and deep wrinkles. The aim of this study was to investigate the effects of Ehwa Makgeolli containing oriental herbs (Glycyrrhiza uralensis Fisch., Lycium chinense MILL., Morus alba L., and Saururus chinensis Baill) on skin whitening and wrinkling in human skin cells. We prepared Makgeolli extracts (HEE) with 70% ethanol. HEE significantly inhibited in vitro mushroom tyrosinase activity and reduced the cellular and secreted melanin content of mouse melanoma melanocytes (B16F1 cells). HEE down-regulated the protein expression of tyrosinase related protein (TRP)-1/-2, a key player in melanogenesis. Treatment with HEE in human keratinoctyes (HaCaT cells) inhibited the proteolytic activities of matrix metalloproteinase (MMP)-2/-9 in a dose-dependent manner and dramatically reduced the expression of MMP-2/-9. In addition, HEE attenuated lipopolysaccharide (LPS)-induced nitric oxide production in murine macrophages (RAW264.7 cells). These results indicate that HEE may be a great cosmeceutical ingredient for its whitening, anti-wrinkle, and anti-inflammatory effects.

  • Melanin is one of the most important factors affecting skin color. Melanogenesis is the bioprocess of melanin production by melanocytes in the skin and hair follicles and is mediated by several enzymes, such as tyrosinase, tyrosinase related protein (TRP)-1, and TRP-2. Convenient enzymatic transformation of the simple phenol pyrogallol with polyphenol oxidase originating from pear to an oxidative product, purpurogallin, was efficient. The structure of the pyrogallol oxidation product was identified on the basis of spectroscopic methods. The biotransformation product purpurogallin showed significant inhibitory effects against both melanin synthesis and tyrosinase activity in a dose-dependent manner in B16 melanoma cells. In addition, purpurogallin significantly attenuated melanin production by inhibiting TRP-1, and TRP-2 expression through modulation of their corresponding transcription factors, and microphthalamia- associated transcription factor in B16 cells. Consequently, purpurogallin derived from convenient enzymatic transformation of pyrogallol might be a beneficial material for reducing skin hyperpigmentation.

  • Hair graying is processed by loss of melanin production caused by the decrease of activity and number of melanocyte and the accumulation of hydrogen peroxide ($H_2O_2$) in the hair follicle with increase of age. The purpose of this study was to investigate the effect the Black oryzasativa ethanolic extract (BLEE) on the melanin production. In this study BLEE at $8{\mu}g/ml$ or more showed a significant 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity and reduction power. BLEE at $16{\mu}g/ml$ or more showed promoted tyrosinase activity and melanin production. In addition BLEE scavenged intracellular $H_2O_2$ in 2',7'-dichlorodihydrofluorescein (DCF) fluorescence assay in B16F1 cells. However, Western blot analyses displayed that BLEE decreased the expression level of catalase, but no effect on the expression level of tyrosinase, tyrosinase associated protein-1 (TRP-1), tyrosinase associated protein-2 (TRP-2) and microphthalmia-associated transcription factor (MITF) transcription factor involved in melanogenesis. Thus, the promotive effect of BLEE on melanin production is attributed to the increase of tyrosinase activity and the reduction of intracellular $H_2O_2$ level. In conclusion, BLEE played a key role in in promoting melanin production, which suggests that the BLEE could be applied as a potential functional material in the development of hair care cosmetics related to the promotion of melanin production for the growth of black hair.

  • The Portulaca oleracea (P. oleracea) is a popular herbal medicine in East Asia that was known to possess detoxification, antifebrile and antifungal effects. In the present study, we examined the biological activities of ethanol extracts of P. oleracea under various conditions with NIH3T3, B16F10, and MCF-7 cell line model systems. Extracts of P. oleracea (0.5 mg/ml) showed inhibition of expression of tyrosinase, but does not suppress either of TYRP-1 or DCT expression on B16F10 cells. Extracts of P. oleracea (2 mg/ml) showed anti-inflammatory effects on TNF-$\alpha$-stimulated NIH3T3/$NF{\kappa}B$-Luc cells and increase of the synthesis of collagen on NIH3T3 (wild type) cells. These results suggest that extracts of P. oleracea could be used as a functional biomaterial in developing a skin whitening agent and having the anti-inflammatory, anti-wrinkle, and anti-aging activities.

  • 피부 노화는 피부와 피부 지지층 등의 광범위한 퇴행 과정을 말한다. 피부 노화의 원인은 흡연, 공해, 스트레스 등이 있지만, 그 중에서도 자외선(ultra violet, UV) 조사가 가장 큰 요인으로 꼽힌다. 반복적인 자외선 조사에 의해 진행되는 피부노화를 광노화라고 하며 그 가장 큰 특징으로는 콜라겐 섬유와 엘라스틴의 감소로 야기되는 주름을 들 수 있다. 본 연구에서는 제주에서 채집한 바위수국의 추출물 및 분획물의 항산화 및 자외선으로 인한 피부노화 예방(anti-photoaging) 효능을 확인하고, 활성물질을 분리하여 광노화 예방 효능과 그 메커니즘을 확인하였다. 실험에 사용된 바위수국은 범의귀과의 덩굴성 식물로 바위면이나 나무줄기 등에 붙어서 자라며, 한국(제주, 울릉도)과 일본에 분포한다. 바위수국 추출물과 분획물에서 총 페놀 함량. 총 플라보이드 함량, DPPH 및 ABTS 라디칼소거 활성의 항산화 실험 결과, 부탄올과 에틸아세테이트 분획층에서 강력한 항산화 활성이 관찰되었다. 또한 UVA를 조사한 인간 진피 섬유아세포 (human dermal fibroblast, HDF)데 대한 콜라겐 분해효소인 matrix metalloproteinase-1(MMP-1) 생성 억제 활성을 확인한 결과, 부탄올 분획층이 세포 생장 저해 없이 가장 우수한 효능이 확인되었다. 따라서 부탄올 분획층에서 주요 성분 분리 실험을 수행하여 총 4개의 화합물을 분리하였다; Chlorogenic acid (1), Quercetin-3-O-glucosyl-(1-2)-rhamnoside (2), Quercetin-3-O-xylosyl-(1-2)-rhamnoside (3), Quercitrin (4). 분리한 4개의 물질의 MMP-1 생성 억제 활성을 비교한 결과 화합물 2가 세포독성 없이 MMP-1 생성 억제 효능이 우수하였고, 이후 화합물 2의 광노화 예방 효능과 그 메커니즘을 확인하였다. 화합물 2는 MMP-1의 생성을 억제할 뿐만 아니라 procollagen type I의 생성을 증가시켰으며, MMP-1 생성에 관여하는 mitogen-activated protein kinase (MAPK)/activator protein-1 (AP-1) 신호전달경로를 하향 조절하며, 콜라겐 생성과 관련된 Transforming growth factor-β (TGF-β)/Smad 신호전달경로를 상향 조절하여 UVA에 의한 광노화 예방에 효능을 나타내었다. 이러한 결과들을 바탕으로, 바위수국은 항노화(anti-aging) 기능성 화장품 및 이너뷰티 기능성 식품 소재로 개발이 가능할 것으로 기대된다.

  • Objectives: The objective of this study was to evaluate the effects of cytotoxicity, skin regeneration, anti-wrinkle, whitening and skin moisturizing of Oncheongeum (OCE).Methods: The cytotoxicity of OCE lyophilized aqueous extracts (yield=13.82%) was observed against human normal fibroblast cells and B16/F10 murine melanoma cells by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium Bromide (MTT) assay, and skin regeneration and anti-wrinkle effects were also evaluated through the assay of collagen type I synthesis compared to the transformation of the growth factor (TGF)-β1, hyaluronidase, collagenase and matrix metalloproteinase (MMP)-1 inhibitory assays compared to oleanolic acid (OA), and elastase inhibitory effects compared to phosphoramidon disodium salt (PP). In addition, OCE’s whitening effects were measured by a tyrosinase inhibitory assay and melanin formation test in B16/F10 murine melanoma cells compared to arbutin, and skin moisturizing effects were observed through a mouse skin water content test, respectively. Results: No OCE treatment-related cytotoxic effects appeared on human normal fibroblasts and B16/F10 murine melanoma cells. OCE concentration-dependently increased the collagen Type I synthesis on human normal fibroblast cells, and also effectively inhibited hyaluronidase, elastase, collagenase and MMP-1 activities. In addition, OCE inhibited melanin production of B16/F10 murine melanoma cells and activity of tyrosinase. And significant and dose-dependent increases of skin water content were detected in OCE-treated mouse skin compared to vehicle control skins. Conclusions: OCE showed favorable and sufficient effects in skin regeneration, anti-wrinkle, whitening and skin moisturizing in this experiment. But more detail mechanisms and studies on the skin protective efficiency of in vivo are needed with the screening of active biological compounds in individual OCE herbs.

  • This study was carried out to investigate the antioxidant effects of extracts from 9 species of forest plants in Korea. DPPH, ABTS, $NaNO_2$, hydrogen peroxide radical scavenging activity and reducing power activity were evaluated to measure the antioxidant activities of plant extracts. As a result, Geranium thunbergii has been identified as the most effective antioxidant resource. Also, total phenolic content was highest in Geranium thunbergii ($303.94{\pm}0.63mg\;GAE/g$) among 9 species extracts. Total flavonoid content was highest in Rosa multiflora ($24.32{\pm}0.22mg\;QE/g$) and proanthocyanidin content was highest in Vitis ficifolia ($279.00{\pm}4.58mg\;CE/g$) among 9 species extracts. In addition, the protective effect of plant extracts in $H_2O_2-induced$ human dermal fibroblast (HDF) cell systems were also assessed. Significant protective effects in $H_2O_2-induced$ human dermal fibroblast (HDF) cell systems were found in all plant extracts, especially in Geranium thunbergii. These results suggest that Geranium thunbergii could be a potential natural resource for antioxidant activity.
