  • The freezed Mulberry (10 kg) was extracted with 80% EtOH, concentrated, and fractionated with a series of n-hexane, ethyl acetate, and water on a separatory funnel. A portion of ethyl acetate soluble (22 g) was chromatographed on a Sephadex LH-20 column using a series of aqueous methanol as eluents. The isolated compounds were identified by cellulose TLC, $^1H-$,$^{13}C$-NMR, FAB, and EI-MS. Quercetin-3-O-${\beta}$-D-glucopyranoside (Compound I), protocatechuic acid (Compound II), p-hydroxybenzoic acid (Compound III) were isolated from the ethyl acetate soluble fraction. In antioxidative activities of the fractionated extractives using DPPH radical scavenging test, EtOAc and water soluble fractions indicated better than BHT as contro and in in vitro tests using MTT assay, there was no cytotoxicity. Also, tyrosinase inhibition and anticancer activities were not so good, but there may be a potential as a cosmetic raw material because the cell extension effect was excellent.

  • The spent coffee grounds (SCG) are considered valuable by-products because they contain various bioactive compounds. The SCG extraction (SCGE) was irradiated at doses ranging between 30 and 50 kGy. The deep dark-brown color of SCGE was changed to a bright yellow color by gamma irradiation. The content of the bioactive compounds of gamma-irradiated SCGE was analyzed by high-performance liquid chromatography. Interestingly, the content of quinic acid was increased by gamma irradiation, whereas other compounds were decreased. Although the contents of bioactive compounds were changed by gamma irradiation, the biological activities (radical scavenging activity and whitening effects) of SCGE were unaffected. Our findings suggest that gamma irradiation can effectively improve the color values of SCGE without the loss of biological activities. Consequently, gamma irradiation can be a useful tool for improving the utilization of SCGE in the cosmetic industry.

  • In this study, various plant extracts were screened for the effective and safe skin care ingredient according to the antioxidant activity assay guidelines. We selected an optimized combination herbal extract, Charmzone extract (CZE), which composed of Nelumbo nucifera leaves, Saururus chinensis and Orostachys japonica. CZE exerted free radical scavenging activity. It reduced reactive oxygen species formation and increased total antioxidant capacities in human keratinocyte (HaCaT) and normal human dermal fibroblasts (NHDF). CZE also leaded procollagen type 1 secretion in NHDF and decreased cellular melanin contents in B16F10. The production of nitric oxide was decreased by CZE in lipopolysaccharide-stimulated RAW264.7 in a dose dependent manner. Therefore, it is concluded that CZE can be applied for naturally derived anti-aging functional skin care ingredient for anti-oxidation, wrinkle enhancement, whitening, anti-inflammation and wound healing of skin.

  • In this study, the antioxidative and inhibitory effects on tyrosinase and elastase of Hippophae rhamnoides (H. rhamnoides) leaf extracts were investigated. The ethyl acetate fraction of H. rhamnoides extracts showed more effective free radical (1,1-diphenyl-2-picrylhydrazyl, DPPH) scavenging activity ($FSC_{50}$ = 4.68 ${\mu}g$/mL). Reactive oxygen species (ROS) scavenging activity ($OSC_{50}$) of the aglycone fraction in the luminol-dependent $Fe^{3+}$-EDTA/$H_2O_2$ system was 0.19 ${\mu}g$/mL. The aglycone fraction exhibited more prominent cellular protective effects (${\tau}_{50}$, 133.3 min at 10 ${\mu}g$/mL) in the $^1O_2$-induced photohemolysis of human erythrocytes. The inhibitory effect ($IC_{50}$) of the aglycone fraction on tyrosinase was 54.86 ${\mu}g$/mL, and more effective than arbutin known as whitening agent. These results indicate that fractions of Hippophae rhamnoides extract can be used as antioxidants in biological system, particulaly skin exposed to UV radiation by quenching and/or scavenging $^1O_2$ and other ROS, and protecting cellular membranes against ROS.

  • 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.

  • This study was to improve cosmetical activity of thiamine di-lauryl sulfate (TDS) by encapsulation of nanoparticle with lecithin. Results showed that most of the nanoparticles containing the TDS were well formed in round shape with below 150 ~ 200 nm diameter as well as they were fairly stable in various pH ranges by measuring zeta potentials. The nanoparticles of TDS resulted in 85% cell viability of human normal fibroblast cells (CCD-986sk) when added at the highest concentration (1.0 mg/mL). The nanoparticles of Acer mono sap showed highest free radical scavengering effect as 88.1% in adding sample (1.0 mg/mL), compared to TDS solution of non-encapsulation (81.6%). The nanoparticles of TDS reduced the expression of MMP-1 on UV-irradiated CCD-986sk cells down to as 41.4%. The TDS solution and nanoparticles showed significant anti-microbial activities agaionst the salmonella typhimurium and listeria monocytogenes at 5 and 6 days as compared with control. Anti-microbial activities of TDS nanoparticles were similar to positive control. These results indicated that TDS nanoparticles may be a source for functional cosmetic agents capable of improving cosmetical activity such as antioxidant, whitening, and anti-wrinkling effects and can be further developed as natural preservative in cosmetics.

  • The objective of this study was to evaluate the effects of far-infrared (FIR) irradiation on the antioxidant and tyrosinase inhibitory activities of Schizonepeta (S.) tenuifolia. After FIR irradiation of S. tenuifolia for 30 min at 70, 90, or $110^{\circ}C$, water extracts (2 g/100 mL) were prepared at $60^{\circ}C$ for 1, 3, or 5 h. Total phenol content (TPC), 1,1-diphenyl-2-picryl-hydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) radical scavenging activities (RSAs), and tyrosinase inhibitory activity of the extracts were determined. TPC, antioxidant and tyrosinase inhibitory activities of the extracts increased significantly with increasing FIR irradiation temperature of S. tenuifolia. For example, irradiation at $110^{\circ}C$ for 5 h increased TPC, DPPH RSA, ABTS RSA, and tyrosinase inhibitory activity of the extract from 204.64 to $618.67{\mu}g$ gallic acid equivalents/mL, from 30.15 to 80.84%, from 24.43 to 55.33%, and from 7.05 to 33.65%, respectively, compared to the extract of untreated S. tenuifolia. These results indicate that FIR irradiation may be useful as a processing method for enhancing the quality of S. tenuifolia.

  • Forsythia fructus has been shown to have antioxidative, anti-inflammatory, antibacterial, anti-aging and whitening effects. This work was carried out to investigate the anti-aging effects of Forsythia viridissima-prescription extracts (Yeongyoseungma-tang, Gamiyeongyoseungma-tang, Hoechunyangkyeok-san) on skin. Skin anti-aging effect of Forsythia viridissima-prescription extracts (Yeongyoseungma-tang, Gamiyeongyoseungma-tang, Hoechunyangkyeok-san) was evaluated by using antioxidant assay, anti-glycation activity, inhibitory effect of tyrosinase activity, expression of type I procollagen and UVA-induced matrix metalloproteinase-1 on HS68 cells, and reduction of ${\alpha}$-MSH-induced melanin on B16F1 cells. Forsythia viridissima-prescription extracts showed anti-oxidative and anti-glycation activity. The pectinex hydrolysed extract from Yeongyoseungma-tang 75% EtOH extract and Gamiyeongyoseungma-tang 75% EtOH extract increased the type I procollagen synthesis, and decreased the UVA-induced MMP-1 expression on HS68 cells. The pectinex hydrolysed extracts of Hoechunyangkyeok-san 75% EtOH extract had the inhibitory effect of melanin synthesis on B16F1 cells. Based on these results, we suggest that Forsythia viridissima-prescription extracts may be useful as a potential source of functional anti-aging cosmetics.

  • Rosemary (Rosmarinus officinalis L.) is widely used as a food material. Although various physiological activities of rosemary have been reported, there have been no studies on the physiological activity of solvent extracts with different polarities. Rosemary extracts were obtained by extraction of dried powder using 0%, 25%, 50%, 70%, and 95% ethanol (EtOH) in distilled water, methanol, ethyl acetate, and hexane. As these ratios of EtOH are generally chosen by default and scarcely optimized, we investigated the impact of the composition of EtOH in distilled water on extract-related characteristics, such as DPPH free radical scavenging and ${\alpha}$-glucosidase inhibition, on the differentiation of 3T3-L1 adipocytes and inhibition of tyrosinase. Adipogenesis inhibition was highest at 70% EtOH. DPPH scavenging activity and inhibition of tyrosinase activity were reduced with 50% EtOH in water. However, inhibition of ${\alpha}$-glucosidase activity was higher in 50% EtOH in water. The best solvents in terms of DPPH scavenging activity, inhibition of tyrosinase and ${\alpha}$-glucosidase, and differentiation of adipocytes obtained with different concentrations of EtOH, although a lower similar activities were found with 50% ethanol. Considering the extraction solvents, a ratio of EtOH in water gives different content and constituents of compounds. These differences will give activities inhibition of adipogenesis, tyrosinase, ${\alpha}$-glucosidase activity, and DPPH scavenging activity.

  • Biorenovation is a biotransformation method that converts the structure of chemical compounds and natural product through biocatalytic metabolism of microorganism and could enhance biological effectiveness and mitigate cytotoxicity compared to its substrates. Althaea rosea L. has been used as oriental medicine and is known for physiological efficacies such as antiurolithiatic, anti-inflammatory, and anti-cancer activities. A. rosea L. callus, the plant tissue grown to protect its wound, has been reported to have antioxidant and whitening effects. However, mechanisms of its other activity such as inflammation have not yet been investigated. In this study, we extracted A. rosea L. callus (AR) and produced biorenovated AR (ARBR), and then analyzed anti-inflammatory effect in Lipopolysaccharide-induced RAW 264.7 macrophage at 50, 100, 200 ㎍/mL of ARBR. As a result of inhibition test of nitric oxide production, it was found that ARBR was superior to AR without apparent toxicity. Furthermore, ARBR significantly inhibited production of prostaglandin E2, inducible nitric oxide synthase, cyclooxygenase-2 and pro-inflammatory cytokines including Tumor necrosis factor-α, Interleukin-6, Interleukin-1β in a concentration-dependent manner. In conclusion, we suggest that ARBR could regulate the excessive inflammatory response to an appropriate level and be a promising material for functional cosmetics and pharmaceuticals.
