  • L-ascorbic acid (vitamin C) is one of the well-known antiviral agents, especially to influenza virus. Since the in vivo antiviral effect is still controversial, we investigated whether vitamin C could regulate influenza virus infection in vivo by using Gulo (-/-) mice, which cannot synthesize vitamin C like humans. First, we found that vitamin C-insufficient Gulo (-/-) mice expired within 1 week after intranasal inoculation of influenza virus (H3N2/Hongkong). Viral titers in the lung of vitamin C-insufficient Gulo (-/-) mice were definitely increased but production of anti-viral cytokine, interferon (IFN)-${\alpha}/{\beta}$, was decreased. On the contrary, the infiltration of inflammatory cells into the lung and production of pro-inflammatory cytokines, tumor necrosis factor (TNF)-${\alpha}$ and interleukin (IL)-${\alpha}/{\beta}$, were increased in the lung. Taken together, vitamin C shows in vivo antiviral immune responses at the early time of infection, especially against influenza virus, through increased production of IFN-${\alpha}/{\beta}$.

  • To investigate the effect of ethanol extract of Saxifraga stolonifera MEERBURGH on skin care, we measured anti-oxidant and anti-aging activity. S. stolonifera ethanol extract itself had anti-oxidant activity in a dose-dependent manner in DPPH radical scavenging. Silica dose-dependently increased the intracellular ROS generation in RAW 264.7 cells. S. stolonifera ethanol extract inhibited silica-induced intracellular superoxide anion generation, $H_2O_2$ and hydroperoxide generation in RAW 264.7 cells. S. stolonifera ethanol extract significantly inhibited both hyaluronidase and elastase activity, also significantly inhibited MMP-1(collagenase) activity as well. In NIH 3T3 fibroblast cells, S. stolonifera ethanol extract significantly increased collagen-like polymer synthesis, which suggesting the S. stolonifera ethanol extract might be used as hydration and anti-wrinkle agents. From the above results, it is suggested that the main ingredients of S. stolonifera ethanol extract play an important role in anti-oxidant and anti-aging activity.

  • To investigate the effect of Plantago asiatica L. Root extract on skin care, we measured anti-oxidant activity and whitening action. As a result of measuring DPPH radical scavenging activity to examine independent anti-oxidation of PRE, there was slight scavenging activity. Fluorescent materials DHE, DCF-DA and DHR were each used to measure superoxide anion, hydrogen peroxide, and hydroperoxide created in RAW 264.7 cells, all concentrations were found to dependently prevent ROS production. Tyrosinase activation was found to be blocked dose-dependant. Melanin production was also prevented dose-dependant, but the effects were slight. Therefore, it is expected to be used effectively in development of functional cosmetic materials.

  • Objectives : The present study compared Aralia continentalis Root and Angelica pubescens Root used in Korea and China respectively concerning their anti-oxidant effect Methods : We tested the anti-oxidant effect through in vitro experiment and in vivo experiment that induced oxidative stress using ethanol. Results : 1. DPPH scavenging activity was stronger in Aralia continentalis Root than in Angelica pubescens Root 2. Superoxide anion radical scavenging activity was similar between Aralia continentalis Root and Angelica pubescens Root 3. The linoleic acid peroxidation inhibition effect was stronger in Aralia continentalis Root than in Angelica pubescens Root. 4. The phenolic component was higher in Aralia continentalis Root than in Angelica pubescens Root. 5. Both Aralia continentalis Root and Angelica pubescens Root increased the concentration of GSH and decreased SOD activity in mice, in which oxidative stress was induced, and the effect was stronger in Aralia continentalis Root. 6. Aralia continentalis Root increased GSH peroxidase activity but Angelica pubescens Root did not have such an effect. 7. Neither Aralia continentalis Root nor Angelica pubescens Root had a significant effect on catalase, ADH and ALDH in mice, in which oxidative stress was induced. Conclusions : Aralia continentalis Root has a stronger anti-oxidant effect than Angelica pubescens Root. Thus, although Aralia continentalis Root is not an original plant recorded in botanical literature, it may be usable based on the data about its effects.

  • 본 연구에서는 화장품 신소재 개발을 위하여 맨드라미(Celosia cristata L.) 식물의 에탄올 추출물을 이용하여 생리활성 효과 정도 및 화장품의 응용에 대한 연구를 하였다. 맨드라미는 자생력이 강하고 전국 어디서나 재배가 용이한 장점을 가지고 있으나 세포수준이나 in vivo에서 맨드라미의 항산화 및 항노화 효과에 대한 실험 결과는 보고된 바 없다. 맨드라미 추출물의 피부 자극성을 알아보기 위해 세포 독성을 관찰하였으며 맨드라미 에탄올 추출물 $100{\mu}g/m{\ell}$에서 89.5%의 비교적 낮은 세포 독성을 나타내어 사람 섬유아세포에서의 세포활성 효과가 우수하였다. DPPH를 이용한 항산화 작용측정에 있어서 맨드라미 에탄올 추출물은 농도 의존적으로 항산화 작용을 나타내었고, $100{\mu}g/m{\ell}$에서 25%의 항산화력을 보였으며, silica에 의한 RAW 264.7 세포내 superoxide anion 생성을 최고 농도인 $100{\mu}g/m{\ell}$에서 49.5%로 억제하여 강한 항산화력을 나타냈으며, DCF-DA를 이용한 세포내 $H_2O_2$ 생성을 측정한 실험에서에서도 맨드라미 에탄올 추출물은 농도 의존적으로 항산화 작용을 나타내어 $100{\mu}g/m{\ell}$에서 73%로 강력하게 항산화력을 보였다. 또한 hydroxyl radical 생성을 모두 농도 의존적으로 억제하여 $100{\mu}g/m{\ell}$에서 69.7%의 강력한 억제력을 나타내어 항산화 효능이 매우 우수하다고 보여진다. 항노화 효능에 있어서 hyaluronidase 억제 결과 농도 의존적으로 효과가 우수하여 최고 농도인 $100{\mu}g/m{\ell}$에서 40%의 높은 억제율을 보였으며, 그 외 elastase에서는 39.7%의 억제율을 나타냈다. 이는 맨드라미가 hyaluronidase나 elastase발현의 전사단계에 관련하거나 혹은 단백질 번역 후 변형 (post-translation modification) 단계에 관여하여 효소를 억제하는 효과를 나타내는 것으로 추정해 볼 수 있다. 결론적으로 자원의 재생산이 용이한 맨드라미의 식용 및 약용 자원으로서의 활용가능성을 시사하며, 맨드라미 추출물을 제조하여 화장품에 응용하면 우수한 보습제 및 항산화제, 노화 방지 화장품을 개발할 수 있다고 판단되어진다.

  • 본 연구의 목적은 8가지 한약재(가지, 금은화, 감초, 천궁, 당귀, 황련, 치자, 연교)로 구성된 가지청열소 독음의 항산화 효과와 항염증 효과를 검증하여 효과적인 화장품소재로서의 가능성을 확인하는 것이다. 한약재의 구성과 비율은 동의보감에 수록된 청열소독음(淸熱蘇毒飮) 처방을 변형시켜 사용하였고 추출은 열수와 70% 에탄올로 하여 동결건조 분말화하였다. 항산화 효능을 확인하기 위해 라디칼 소거능력(DPPH, $ABTS^+$, superoxide), superoxide dismutase (SOD)유사활성능력, 총 폴리페놀 화합물 함량을 조사하였고 항염증 효능을 확인하기 위해 LPS (lipopolysaccharide)로 염증반응을 유도시킨 RAW264.7 대식세포에서의 nitric oxide(NO)생성 저해력과 western blot 분석을 통한 염증 관련 단백질 inducible nitric oxide synthase (iNOS)와 cyclooxygenase (COX-2)의 발현 저해를 확인하였다. 그 결과, 가지청열소독음은 뛰어난 항산화 효과와 항염증 효과를 나타내었고 화장품을 위한 효과적인 성분으로 사용 가능할 것으로 사료된다.

  • 본 연구는 피부 관리에 사용되는 천연화장품 원료로서 동과자 추출물의 활용 가능성을 조사하기 위해 항산화, 항염 그리고 미백 효능을 평가하였다. DPPH 자유라디컬 소거 활성은 농도 의존적으로 감소하였으며, 총폴리페놀 함량은 메탄올추출물(22.42±0.002 mgGAE/g)이 열수추출물(9.77±0.002 mgGAE/g)보다 더 높게 나타났다. MTT assay 결과 동과자 추출물에 의한 RAW264.7 세포와 B16F10 세포에서의 세포독성은 없었다. 또한 LPS 처리에 의해 활성화된 RAW264.7 세포에서 NO 생성과 TNF-α 분비 억제능을 확인하였다. B16F10 melanoma 세포에서 동과자 추출물은 α-MSH에 의한 멜라닌 합성을 유의하게 저해하는 것으로 나타났다. 게다가, westernblot 분석결과 동과자 메탄올추출물은 MITF, TRP-1 및 TRP-2 단백질의 발현 수준을 현저하게 감소시켰다. 이상의 결과로 동과자 추출물은 항산화, 항염 그리고 미백 효능을 가진 기능성 화장품 소재로써의 가치가 높을 것으로 사료된다.

  • To investigate the effect of peanut sprout extract on skin care, we measured anti-oxidant activity and whitening action. As a result of measuring DPPH radical scavenging activity to examine independent anti-oxidation of peanut sprout extract, there was strongly scavenging activity. Fluorescent material DCF-DA was used to measure hydrogen peroxide created in RAW 264.7 cells, and all concentration dependently decreased ROS production. As a result of measuring nitric oxide to examine anti-inflammation of peanut sprout extract, there was strongly inhibited nitric oxide production in RAW 264.7 cells. Tyrosinase activation was found to inhibited dose-dependant. Melanin production was also prevented dose-dependant. Therefore, it is expected to be used effectively in development of functional cosmetic materials.
