  • The enhancement effects of sea mustard extract (SME), starfish collagen peptide (SCP) and a mixture of the two (MIX) on skin activity were evaluated to investigate the possibility of using marine-derived extracts as cosmetic additives. The anti-inflammatory activity, whitening activity and skin elasticity activity of the extracts were analyzed to evaluate their skin-activating effects. Inhibiting the generation of nitric oxide (NO) and the tyrosinase and elastase inhibitory activities were assessed as the bio-markers for evaluating skin activity. SME, SCP and MIX did not show cytotoxicity within the concentration range of 1.0-50 ㎍/mL. In addition, SME, SCP and MIX all increased NO production and the tyrosinase and elastase inhibitory activities in a concentration-dependent manner. The activity of MIX was significantly increased compared to that with using SME or SCP alone. Taken together, when natural extracts are applied as cosmetic additives, the results demonstrate that using a mixture of SME and SCP may have a greater synergistic effect than that when using only a single extract. Therefore, this study contributes to the knowledge about the kinds and composition of several natural extracts when they are used as cosmetic additives.

  • The contents of total phenolics and flavonoids, antimicrobial and tyrosinase inhibition activities of five growth stages with four greenhouse-grown cucumber extracts were investigated. Total phenolic content was high in Jangjukcheongjang, Janghyeongnakhap and five growth stage(24~27 cm). The content of total flavonoid did not differ between cultivar or growth stages. Among the four cucumber cultivars, the extract of Janghyeongnakhap showed a relatively strong antimicrobial effect against Staphylococcus aureus. The inhibition zone against Staphylococcus epidermidis of the samples tested in this experiment was 8~12 mm. And the antimicrobial effects against Malassezia furfur was high in Jangjukcheongjang, and showed the highest by the inhibition zone of 14mm in three(17~20 cm) growth stage. The tyrosinase inhibition activity of cucumber extracts showed relatively high activity in Jangjukcheongjang and Sinjoeunbaekdadagi, followed by Janghyeongnakhap. From these results, we confirmed that the extract of cucumber has high antimicrobial and whitening efficacy, and that in the future, the cucumber will be increase the availability in the field of high-value cosmetic materials.

  • 매실나무겨우살이 막걸리의 생리적 효능을 검정하여 의약 화장품의 소재화 가능성을 검토할 목적으로 발효기간과 겨우살이 함량에 따른 총 폴리페놀, 플라보노이드 함량, DPPH free radical 소거능을 측정하였고, tyrosinase 저해활성은 5분 간격으로 65분간 측정하였다. 막걸리는 백미와 기장을 7:3의 비율로, 겨우살이의 함량을 0%, 5%, 10%로 달리하여 10일 간격으로 최대 30일까지 Shaking incubator($30{\sim}35^{\circ}C$, 100 rpm)에서 발효하였고, 발효가 끝난 막걸리는 80 mesh 망으로 여과하였다. 총 폴리페놀 함량은 10일에 최대치를 나타내었고, 0%는 $633.53{\mu}g/ml$, 5%는 $759.67{\mu}g/ml$, 10%는 $752.2{\mu}g/ml$을 나타내었다. 기간이 경과함에 따라 감소하는 경향이었으며 30일에 0%는 $507.57{\mu}g/ml$, 5%는 $570.13{\mu}g/ml$, 10%는 $551{\mu}g/ml$를 함유하고 있는 것으로 나타났다. 총 플라보노이드 함량 또한 10일에 최대치를 나타내었고, 0%는 $16.18{\mu}g/ml$, 5%는 $63.87{\mu}g/ml$, 10%는 $62.99{\mu}g/ml$였고, 기간이 경과함에 따라 감소하는 경향성을 나타내어 30일에 0%는 $0.59{\mu}g/ml$, 5%는 $10.98{\mu}g/ml$, 10%는 $1.18{\mu}g/ml$를 함유하였다. DPPH free radical 소거능은 0%의 경우 10일에 72.34%로 최대치가 나타났고, 30일에 58.61%로 가장 낮은 소거능을 보여주어 기간이 경과함에 따라 감소하는 경향성을 보여주었다. 하지만, 겨우살이 첨가군인 5%(10일:91.13%, 20일:91.09%)와 10%(10일:91%, 20일:90.8%)는 비교적 차이가 없었고, 발효기간이 30일이 경과한 후 5%는 93.46%, 10%는 92.3%로 최대값을 보여주었다. Tyrosinase 저해활성은 DPPH free radical 소거능이 가장 좋은 30일 발효 막걸리를 측정하였다. 모든 겨우살이 첨가군에서 5분이 경과하였을 때, 0%는 82.68%, 5%는 69.29%, 10%는 79.53%의 저해활성을 나타내었으며, 시간에 유의적으로 저해활성이 감소하였다. 본 연구 결과에 따르면, 겨우살이 막걸리의 총 폴리페놀과 플라보노이드 함량은 기간이 경과함에 따라 감소함에도 불구하고, DPPH free radical 소거능은 증가함을 알 수 있었다. Tyrosinase 저해활성은 5% 첨가 막걸리에서 가장 낮았으며, 겨우살이를 첨가하지 않은 0%에서 가장 저해활성이 높고 오랜시간 유지되는 것을 확인할 수 있었다.

  • Hwangryunhaedoktang (HHT) has been traditionally used as a preventive and therapeutic medicine to treat enervation and diverse chronic diseases. This study was designed to compare the antioxidant, anti-wrinkle and whitening effects of HHT extract and its fermented extract by Leuconostoc mesenteroides (FHHT). FHHT was prepared by inoculation of L. mesenteroides after the extraction procedure with 70% ethanol. HHT and FHHT was investigated via high-performance liquid chromatography (HPLC). Simultaneous qualitative analysis of two bioacitive components, berberine and palmatine. was achieved by comparing their retention times ($t_R$) and UV spectra with those of the standard components. Cell viability test results indicated that both HHT and FHHT were non-toxic. In DPPH radical scavenging ability, $SC_{50}$ values of the FHHT was $68.85{\mu}g/mL$, which is more effective than HHT. Moreover, FHHT showed higher expression in production of procollagen type I than HHT. In nontoxic concentration range, FHHT showed strong melanin production inhibitory effect in ${\alpha}-melanocyte$ stimulating hormone (${\alpha}-MSH$)-stimulated B16F10 cell ($IC_{50}=9.82{\mu}g/mL$). These results suggested that fermented extracts of hwangryunhaedoktang had considerable potential as a cosmetics ingredient with an antioxidant and anti-wrinkle and whitening effects.

  • In order to search for new whitening cosmetic ingredients from Chinese herbal extracts including Chinese herbs and complex prescriptions from TCM (Traditional Chinese Medicine), we screened about 47 TCM extracts collected from China. We tested their inhibitory effects on melanogenesis by using in vitro tyrosinase inhibition assay and B16 melanoma cells. We selected Siphonostegia chinensis and Salvianic miltiorrhiza Bunge. We isolated Danshensu ($\alpha$,3,4-trihydroxybenzenepropanoic acid sodium salt) from Salvianic miltiorrhiza Bunge extract and tested its inhibitory effect on melanin formation in B16-F10 melanoma cells. Danshensu suppressed melanin synthesis up to about 50% at a concentration of $100\;{\mu}g/mL$. Siphonostegia chinensis suppressed melanin synthesis up to about 60% at a concentration of $300\;{\mu}g/mL$. The results showed that these extracts could be used as new natural active ingredients for whitening cosmetics.

  • To investigate the potential use of makgeolli by-products as cosmetic materials, their phenolic and kojic acid contents, antioxidant activity, whitening effect, and anti-wrinkle activity were evaluated. Extracts were obtained with five different solvents (containing 0, 25, 50, 75, and 100% ethanol) from nuruk lees (NL), rice lees (RL), raw makgeolli (RM), and commercial makgeolli (CM) at 20 and $50^{\circ}C$. NL and CM extracts prepared with 75% ethanol had the highest phenolic contents (13.26 and 16.66 mg gallic acid equivalents/g, respectively) at 20 and $50^{\circ}C$, respectively. The highest kojic acid content was found in NL extracts with 0% ethanol at $20^{\circ}C$, while kojic acid was not detected in extracts prepared at $50^{\circ}C$. NL and RL extracts at $20^{\circ}C$ showed significant antioxidant activity. Whitening effects, determined by tyrosinase inhibitory activity, were highest for the NL extract prepared with 75% ethanol at $50^{\circ}C$. Noticeable anti-wrinkling effects, estimated by elastase inhibition activity, were also found in NL and RL extracts. These results suggest that makgeolli by-products could be valuable cosmetic materials with antioxidant, whitening, and anti-wrinkle activities.

  • Sedum kamtschaticum Fisch., a native plant of Korea, has been used in Korean traditional medicine in the form of water extract for its capacity to improve blood circulation and for its antioxidant and anti-inflammatory effects. Since previous research suggests that S. kamtschaticum Fisch. has excellent antioxidant and mushroom tyrosinase inhibition activities, in this study, the root and stem parts of S. kamtschaticum Fisch. are extracted in 70% ethanol (SKS, SKR), fractionated with and in order of n-hexane (SSH), ethyl acetate (SSE, SRE), chloroform (SSC, SRC) and water (SSW, SRW) according to the polarity of each solvent, and tested for its applicability as a cosmetic material. According to the total polyphenol, flavonoid contents and DPPH radical scavenging activity of each fraction, the contents and scavenging activity of the root extractions (SKR) were higher than those of the stem extractions (SKS), ethyl acetate fractions (SSE, SRE) being the most effective. In addition, ethyl acetate fractions had the highest tyrosinase inhibition activity and melanin synthesis inhibition activity used on B16F10 melanoma cells, at the concentration of 10 ㎍/mL. HPLC analysis detected a variety of polyphenols including gallic acid and quercetin. This study suggests the potential role of S. kamtschaticum Fisch. as a natural cosmeceutical material.

  • The coffee silver skin is a part of coffee beans. We report that the coffee sliver skin extracts exhibited cosmetic properties of antioxidant, anti-winkle and whitening effects. The ethanol extracts of silver skin showed free radical scavenging activity up to 92.26% in $50{\mu}g/mL$, especially against DPPH radical and ABTS radical cation. The silver skin extracts showed inhibitory effects for tyrosinase activity and DOPA oxidation in a dose-dependent manner, suggesting the extracts retain for the whitening property in cosmetics. The coffee silver skin extracts effectively inhibited the elastase and collagenase. Cytotoxicity of the coffee silver skin extracts was measured by the colorimetric MTS assay. The viability of the human keratinocytes (HaCaT) treated with the coffee silver skin extracts was same as that of untreated cells, indicating the extracts are safe to human cells. Here, we suggest that the silver skin extracts of coffee bean could be a potential natural substance for anti-winkle, whitening, antioxidant properties for cosmetics.
