  • Smilax china root has been used as traditional medicinal remedy in China and Korea and reported to have various biological activities such as anti-inflammatory, antimutagenic and antimicrobial activities. In this study, the possibility of development as natural antioxidants of Smilax china root extracts was investigated. For the evaluation of antioxidant activity, aqueous- and 25% EtOH extract from Smilax china root were prepared and six different evaluation assay methods, i.e., measurement of total phenolics, radical scavenging effects on 1,1-diphenyl-2-picrylhydrazyl (DPPH), nitric oxide (NO) and nitrite $(NO_2)$, reducing power, and inhibitory effect on tyrosinase activity, were used. The total phenolics content of two extracts was high as the level of 36 mg of gallic acid equivalent per 1 g of dried sample tested. The radical scavenging activities of ethanol extract toward DPPH and NO were better than those of aqueous extract (p<0.05). The $NO_2$ scavenging activity of both extracts showed the highest value at pH 1.2 (98%). Especially, the $NO_2$ scavenging activities of EtOH extract were significantly stronger than those of aqueous one at pH 4.2 (51%) and pH 6.0 (32%), respectively. In the reducing power test, both extracts revealed higher ferric ion reducing activity than known antioxidant, vitamin C at the level of $0.05\sim0.1mg/mL$ (p<0.01). The 1 mL of aqueous and 25% EtOH extract showed effective inhibition activity on tyrosinase activity as 45% and 53%, respectively. Therefore, these results suggest that two extracts from Smilax china root may serve as useful natural antioxidants.

  • The physiological properties of extracts from Hizikia fusiforme with different extraction methods (hot water extraction, autoclave extraction and high pressure extraction) were investigated. The amounts of substances related to polyphenol and flavonoids contents were the highest in autoclave extract (30.51 mg/g and 4.78 mg/g, respectively). The DPPH radical scavenging activity was the highest in the autoclave extract (81.80%) at the 5 mg/mL. Autoclave extract exhibited the strongest ABTS radical scavenging activity and reducing power among the three extraction methods. However, ferrous ion chelating, TBA reactive substances and xanthine oxidase inhibition activity of high pressure extract were higher than those of the other extracts. Additionally, the tyrosinase and elastase inhibition activities of high pressure extract with a concentration of 1 mg/mL were higher than those of the other extracts. These results suggest that extracts of Hizikia fusiforme have a potential to act as functional materials, and autoclave and high pressure extractions are superior to hot water extraction for enhancement of the biological activity.

  • This study was designed to determine the biological activities of Chionanthus retusus flower extracts. Water and 90% ethanol extracts of C. retusus flower were prepared. The inhibitory activities of water and ethanol extracts with a phenolic content of $200{\mu}g/mL$ against xanthine oxidase were 25.60% and 15.92%, respectively. Further, the water extract did not show any inhibitory activity against ${\alpha}$-glucosidase whereas the ethanol extract showed 100.00% inhibition of ${\alpha}$-glucosidase. The inhibitory activities of the extracts against tyrosinase were 17.27% (water extract) and 36.13% (ethanol extract), which suggest that the extracts may have a whitening effect. The water extract did not inhibit elastase activity but showed a collagenase-inhibitory activity of 20.21%. On the contrary, the ethanol extract showed 96.26% and 35.93% inhibition of collagenase and elastase, respectively. These findings suggest that the extracts may have an anti-wrinkle effect. Lastly, the extracts showed a hyaluronidase inhibitory activity of 36.96% (water extract) and 88.70% (ethanol extract), suggesting that they may have an anti-inflammatory effect. The results indicate that C. retusus flower extracts containing phenolic compounds can be used as functional resources because they have anti-gout, carbohydrate degradation-inhibitory, whitening, anti-wrinkle, and anti-inflammatory effects.

  • In this study, Camellia sinensis Leaf cultivated in Boseong was extracted by vacuum distillation and hydrothermal extraction methods, and we performed in vitro experiments such as antioxidant, anti-wrinkle, whitening, and antibacterial activity test and HPLC analysis. Wrinkle improvement (elastase inhibition assay) and whitening effect (mushroom tyrosinase inhibition assay) of Boseong vacuum distilled extract have excellent results and IC50 values of vacuum distillation extract was measured at a lower concentration than that of the hydrothermal extract. The antioxidant activity of the Boseong hydrothermal extract was excellently measured in DPPH radical and ABTS+ radical scavenging activity, SOD-like activity, and total polyphenol content. In the antibacterial experiment, the Boseong hydrothermal extract formed a clear zone for the Staphylococcus aureus and Cutibacterium acnes strain. As a result of HPLC analysis, EGCG and caffeine in the hydrothermal extract were 40.29 mg/g, 9.94 mg/g respectively, and caffeine in the vacuum distilled extract was 3.40 mg/g. Therefore, we examined that Boseong Camellia sinensis vacuum distilled extract has excellent anti-wrinkle and whitening effect, and its hydrothermal extract has good antioxidant and antibacterial efficacy.

  • 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.

  • Saccharomyces lysate has the well-known function of soothing the skin in various ways: it is an anti-irritant and can treat skin care conditions, such as skin whitening and antioxidative activity. However, data on the safety for use of Saccharomyces lysate in cosmetics and skin care products are still limited. To design a new cosmetic material with antioxidant and skin-whitening effects, 80 yeast strains were isolated from berries grown in Sunchang. Among the isolates, the FT4-4 strain, which exhibited superior biological activities, was selected for further experiments. The FT4-4 strain was identified as Saccharomyces cerevisiae by 18S rRNA gene sequencing analysis. S. cerevisiae FT4-4 showed higher DPPH radical-scavenging (51.41%), superoxide dismutase (62.23%), and tyrosinase inhibition (64.75%) activities. The highest yield of biomass (3.16 g/l) and maximum growth rate of S. cerevisiae FT4-4 were observed within 16 h. Furthermore, the cytotoxicity potential of S. cerevisiae FT4-4 on B16F10 melanoma cells was measured by an MTT assay, and the results indicated that S. cerevisiae FT4-4 had a capacity to inhibit melanin up to 72.02% at an initial 10 mg/ml concentration. These results suggest that S. cerevisiae FT4-4 could be a promising candidate as a multi-functional material for application in the cosmetic industry, especially because of its antioxidant and skin-whitening effects.

  • We have previously found that mycelia culture broth of eight kinds of traditional herbal extracts fermented with Phellinus linteus (previously named as 8-HsPLCB) not only inhibited melanin and tyrosinase activity, but also reduced the contents of melanogenesis-related proteins, including tyrosinase and microphthalmia-associated transcription factor, in 3-isobutyl-1-methylxanthine-stimulated B16F0 melanoma cells. For a further study, the effect of 8-HsPLCB against skin pigmentation in brown guinea pigs with ultraviolet B (UVB)-induced hyperpigmentation was investigated. 8-HsPLCB (3%) and arbutin (2%) as positive controls were applied topically twice daily for 4 weeks to the hyperpigmented areas. 8-HsPLCB showed skin-lightening effect as effective as arbutin, one of the most widely used in whitening cosmetics. Melanin index values as the degree of pigmentation showed a significant reduction week by week post 8-HsPLCB treatment and then substantially reduced by 4 weeks. The degree of depigmentation after 4 weeks of topical application with 8-HsPLCB was 32.2% as compared with before treatment (0 week). Moreover, using Fontana-Masson staining and hematoxylin-eosin staining, 8-HsPLCB reduced melanin pigmentation in the basal layer of the epidermis and epidermal thickness changes exposed to the UV-B irradiation as compared with non-treatment and vehicle treatment. The intensity of the skin-lightening effect of 8-HsPLCB was similar to arbutin. These results suggest that the skin-lightening effect of 8-HsPLCB might be resulted from inhibition of melanin synthesis by tyrosinase in melanocytes. To conclude, 8-HsPLCB treatment showed reduction of the melanin pigment and histological changes induced by UV irradiation in brown guinea pigs.

  • We evaluated the efficacy of Geranium thunbergii (GT), which has so far been understudied as a cosmetic material, and conducted anti-inflammatory-related activity studies. We measured the electron donation ability and ABTS+ radical scavenging ability to confirm the antioxidant ability of GT and found values of 91% and 94% at a concentration of 50 ㎍/ml, respectively, confirming that GT had excellent antioxidant ability. Tyrosinase inhibitory activity was measured to evaluate whitening activity, and it was found that inhibitory activity was 24.8% at the highest concentration of 1,000 ㎍/ml. Elastase and collagenase inhibitory activity were measured to determine the wrinkle improvement activity of the GT; 30.6% and 90% inhibitory activity were shown at the highest concentration of 1,000 ㎍/ml, respectively. Excellent inhibitory activity was confirmed through the measurement of collagenase inhibitory activity. Before the cell experiments were conducted, the survival rate of the macrophages Raw 264.7 according to GT treatment was determined based on the MTT assay, and the cell survival rate was greater than 83.6% at a concentration of 100 ㎍/ml. Subsequent cell-related experiments were conducted at concentrations of 100 ㎍/ml or less. The NO production inhibitory activity according to the GT treatment by NO assay was measured, and a 74.9% inhibitory rate was confirmed at a concentration of 100 ㎍/ml. Western blotting was performed to determine protein expression inhibition, and both COX-2 and iNOS factors were concentration-dependently inhibited in GT. Based on these results, GT is considered to have potential as an anti-inflammatory functional cosmetic material.

  • Several hydroxycinnamic acid derivatives, p-coumaric acid, ferulic acid, N,N'-dicoumaroylputrescine (DCP), N-p-coumaroyl-N'-feruloyl-putrescine (CFP), and N,N'-diferuloylputrescine (DFP) were isolated and purified from corn bran. To develop the skin whitening agent, we investigated the effects of hydroxycinnamic acid derivatives from corn bran, on melanogenesis. CFP and DFP inhibited melanin synthesis in a dose dependent manner up to 44.7 ${\pm}$ 6.0 %, and 58.5 ${\pm}$ 3.1 % at a concentration of 50 ${\mu}g/mL$, respectively. The intracellular tyrosinase activity decreased about 42.5 ${\pm}$ 14.6 %, and 9.0 ${\pm}$ 4.4 % at a concentration of 50 ${\mu}g/mL$ of CFP and DFP, respectively. Our results suggest that inhibitory effects of hydroxycinnamic acid derivatives on melanogenesis are due to the inhibition of the intracellular tyrosinase activity. These results indicate that these hydroxycinnamic acid derivatives from corn bran may be potential natural skin whitening agents.
