In this study, we evaluated the anti-oxidative, whitening and anti-wrinkle effect of Tetrapanax papyriferum extract. Tetrapanax papyriferum was extracted by two different solvents which were n-Hexane, ethyl acetate. The anti-oxidant activity was measured by free radical scavenging activity using DPPH (1,1-diphenyl-2-picrylhydrazyl radical). And the inhibitory activities of tyrosinase for whitening effect and collagenase, elastase for anti-wrinkle were investigated. For anti-oxidant activity, ethyl acetate fraction of Tetrapanax papyriferum extract showed more significant activity than n-Hexane fraction of Tetrapanax papyriferum extract. For whitening activity, n-Hexane fraction of Tetrapanax papyriferum extract exhibited strong inhibition effects compared with reference. Therefore, Tetrapanax papyriferum extract may be useful as a new antioxidant and whitening agent.

In the aged skin especially in the face and eyelid, deep and slight wrinkles are one of the remarkable phenomena of aging and the cause of wrinkle is various. Among the cause of wrinkles an oxidative stress plays an important roles in wrinkle formation process. It caused the lipid peroxidation of cell membrane, the increase of the MMPs(MatrixMetalloProteinase) gene expression and cellular DNA damage. These ROS induced materials may cause the degradation of collagen matrix system in the dermis and cause the formation of skin wrinkle. So, it is very important for protecting skin wrinkle formation to regulate ROS activity. In this study, we developed one active ingredient having multi functional activities such as activation of collagen synthesis, inhibition of MMPs activity, lipid peroxidation and free radical scavenging activity and inhibition of free radical induced DNA damage in vitro. Pericarpium castaneae extracts showed collagen synthesis increase in Normal Human Fibroblast and the inhibition of elastase activity (IC$\_$50/ of Elastase: 43.9$\mu\textrm{g}$/㎖). It showed also anti-oxidative activity (IC$\_$50/ : 48$\mu\textrm{g}$/㎖) and free radical scavenging activity(IC$\_$50/: 7.6$\mu\textrm{g}$/㎖). Conclusively, Pericarpium castaneae extracts may be used as an ingredient for new anti-wrinkle cosmetics.

In this study, the antioxidant, anti-xanthine oxidase, anti-melanogenic and anti-wrinkle effects of methanol (ME) and hot water (HE) extracts from the fruiting bodies of Phellinus vaninii were investigated. The 1,1-diphenyl-2-picryl-hydrazyl free radical scavenging activity of 2.0 mg/mL HE (95.38%) was comparable to that of butylated hydroxytoluene (96.97%), the reference standard. The hydroxyl radical scavenging activities of ME (98.19%) and HE (97.55%) were higher than that of butylated hydroxytoluene (92.66%) at 2.0 mg/mL. Neither ME nor HE was cytotoxic to murine melanoma B16-F10 cells at 25-750 ㎍/mL. Although the xanthine oxidase (XO) inhibitory effects of ME and HE were significantly lower than that of allopurinol, the values were higher than 84 percent. The in vitro tyrosinase inhibitory activities of ME and HE were comparable to kojic acid at 2.0 mg/mL. The cellular tyrosinase and melanin synthetic activities of ME and HE on B16-F10 melanoma cells at 500 ㎍/mL were higher than arbutin, indicating that the inhibitory effects of arbutin on the tyrosinase and melanin synthesis were higher than those of ME and HE. The collagenase inhibitory activity of HE was comparable to EGCG at 2.0 mg/mL, however, the elastase inhibitory activity of ME and HE was lower than EGCG at the concentration tested. The study results demonstrated that the fruiting bodies of Ph. vaninii possessed good antioxidant, anti-xanthine oxidase, cell-free anti-tyrosinase, cellular anti-tyrosinase, anti-collagenase, and moderate anti-elastase activities, which might be used for the development of novel anti-gout, skin-whitening, and skin anti-wrinkle agents.

Objectives : This study was aimed to report the anti-wrinkle effects of cultivated wild ginseng pharmacopuncture. Methods : Data were collected from 23 patients who had been treated with cultivated wild ginseng pharmacopuncture for skin wrinkles. Patients were treated twice a week, for a total of 5 times. To observe the effect of the treatment, we measured the width and depth of skin wrinkles with ECOSKIN(portable fluorescent dermal diagnostic equipment). We also conducted a survey with patients to measure total satisfaction and the anti-wrinkle effect using a semantic differential scale. The evaluation was done 2 times, once before the first treatment and once 1 week after the last treatment. The relationship was measured by Wilcoxon signed rank test. Results : Skin wrinkle mean width decreased significantly from $9.45{\pm}6.60$ to $5.54{\pm}4.78$. Depth decreased significantly from $0.68{\pm}0.34$ to $0.39{\pm}0.24$ total satisfaction increased significantly from $2.46{\pm}0.743$ to $4.13{\pm}0.51$. Anti-wrinkle effect increased significantly from $2.46{\pm}0.63$ to $3.93{\pm}0.593$. Conclusions : These results suggest that cultivated wild ginseng pharmacopuncture may be effective for decreasing wrinkles.

건강한 피부 기능의 악화 원인으로는 콜라겐 섬유 감소, 탄력섬유 변성, 활성산소종의 과다 생성 등이 있다. 이로 인하여 피부 탄력 저하나 주름이 생성된다. 피부 탄력 저하 및 주름 생성과 같은 피부 노화를 개선하기 위해 대표적으로 비타민 A, C 및 그 유도체들이 화장품에 적용되고 있지만 화학적 불안정성의 문제점이 있어 새로운 유도체들의 합성 개발에 노력을 기울이고 있다. 본 연구에서는 피부개선을 위한 화장품 원료로 최근 비타민 C로부터 새롭게 합성된 3-O-cetyl-L-ascorbic acid (VCCE)의 주름 개선과 관련된 효능 효과를 평가하였다. VCCE의 in vitro 실험 결과 procollagen type I의 합성을 0.002%에서 최대 149% 증가시켰다. 또한 인체적용시험에서 일차적으로 폐쇄 첩포 실험 결과 자극이 유발되지 않았으며, 모사판 분석 및 PRIMOS system을 이용한 주름측정결과에서도 주름개선효과를 확인하였다. 결과적으로, VCCE는 주름 개선을 위한 화장품 성분으로서 높은 응용 가치를 제시한다.

Pericarpium castaneae extracts have variously potent activities, such as anti-oxidative activity and free radical scavenging activity. in vivo and in vitro studies both indicate that pericarpium castaneae extracts acts as a free radical scavenger($IC_{50}:7.6{\mu}g/ml$) stronger than gallic acid($IC_{50}:12.5{\mu}g/ml$) and ellagic acid($IC_{50}:15{\mu}g/ml$) which could prevent cutaneous UV damages and skin aging. The extracts showed a good effect as a anti-oxidant($IC_{50}:50{\mu}g/ml$). It was shown that the appearance of wrinkle in human skin was reduced by topical application of pericarpium castaneae extracts. And the treatment of human skin with the extracts increased the elasticity and moisture of the skin. We investigated the effect of the pericarpium castaneae extracts on production of extracellular matrix using cultured A431 fibroblast cells. The results indicated that the extracts had no detectable effect on collagen synthesis. But synthesis of cell adhesion protein was increased by the extracts. The results suggest that increase of cell adhesion protein synthesis by pericarpium castaneae extracts has closely related to reduction of wrinkle in skin.

To examine the possibility of using Musa sapientum L. (Banana) leaf extract as a cosmetic raw material, banana leaves grown in Jeju Island were extracted with 70% ethanol. Polysaccharides present in banana leaf extract were discarded by precipitation with cold ethanol. Polysaccharide-discarded banana leaf extract promoted procollagen and COL1A1 gene expression, but inhibited matrix metalloproteinase (MMP)-1 and MMP-2 gene expression in human skin fibroblasts when examined by real-time reverse-transcription polymerase chain reaction (RT-PCR) and enzyme-linked immunosorbent assay (ELISA). The active compound in banana leaves was identified by fractionation with various solvents. The chloroform fraction showed the highest anti-wrinkle efficacy and the active compound of chloroform fraction was identified as corosolic acid by NMR, FT-IR, EA, and HPLC-MS. In addition, banana leaf extract showed anti-oxidative efficacy with an IC50 value of 67.91 ppm, as determined by DPPH free radical scavenging assay. Finally, the anti-wrinkle efficacy of banana leaf extract-containing cream was confirmed by clinical tests. Based on these results, banana leaves could have an application as a cosmetic raw material with anti-wrinkle efficacy.
