To check the possibility of using natural extracts for cosmetic substances, we tested the bioactive effects of 11 crude extracts originating from native plants grown in the Republic of Korea on anti-oxidant and anti-wrinkle activities. When DPPH scavenging activities were measured, the crude extracts of Vitex rotundifolia, Scirpus triangulatus, S. wichurae, S. tabernaemontani, and Aeschynomene indica assays had more than 70% of DPPH scavenging activities at 100 μg/ml concentration. The data from the hydrogen peroxide scavenging assay revealed that the crude extracts from the 10 species, except for Eleocharis mamillata var. cyclocarpa, could scavenge more than 90% at 1,000 μg/ml concentration. The crude extract of V. rotundifolia had the highest xanthine oxidase scavenging activity at a 1,000 μg/ml concentration. Based on the four anti-oxidant assays, the crude extracts of V. rotundifolia, S. triangulatus, S. wichurae, S. tabernaemontani, and A. indica were shown to have excellent anti-oxidant capacities overall. In addition to the anti-oxidant capacities, the crude extract from S. wichurae exhibited high collagenase inhibitory activity, therefore, it could be a promising candidate for a cosmetic ingredient with anti-oxidant and anti-wrinkle qualities. The results of this study indicate that many wild plants native to the Korea Peninsula can be used as excellent natural substances for cosmetics based on their bioactive effects.

Objectives : To investigate the effects of Ohbaesangami (OBSGM) on mucosa and skin diseases, anti-microbial and anti-inflammatory tests were performed using several in vitro test models. Results : In anti-microbial test, OBSGM showed the slight inhibitory effect against Propionibacterium acnes (P. acnes) and Staphylococcus aureus (S. aureus). In anti-oxidant test, OBSGM showed the potent radical scavenging activity. In anti-inflammatory test, OBSGM weakly inhibited the lipopolysaccharide (LPS)-induced nitric oxide(NO) release from the RAW 264.7 macrophage cells. OBSGM also inhibited the LPS-induced $interleukin-1{\beta}(IL-1{\beta})$ and cyclooxygenase-2 (COX-2) expressions. The inhibitory effects of OBSGM on macrophage activation was via the inhibition of $NF-{\kappa}B$, evidenced by transient transfection assay. Furthermore, OBSGM markedly inhibited the activation of Jun-N-terminal kinase (JNK) and p38 MAP kinase in RAW 264.7 cells. In skin wrinkle formation assay, OBSGM strongly inhibited collagnease and elastase, whose activities are tightly related with the wrinkle formation. In addition, OBSGM inhibited the activities of MMP-1, MMP-2 on the mRNA levels in RAW 264.7 cells. However, OBSGM did not show an inhibitory potential on tyrosinase activity and melanin synthesis, indicating that it could not be applicable for skin whitening. Conclusion : These results suggest that the anti-inflammatory effect of OBSGM may be due to its inhibitory potentials on the macrophage activation. And, the anti-wrinkle effects of OBSGM may be due to its inhibitory potential on the collagnease and elastase activities. Therefore, OBSGM could be applicable for the treatment of mucosa and skin diseases.

The purpose of this study was to investigate the effects of Cuscuta chinensis Lamark ethanol extract (CL) on wrinkle improvement. Cuscuta chinensis Lamark is known to contain dried saccharide, alkaloids, flavonoids, lignans and rein glycoside as major components of dried mature seeds of Cuscuta japonica Choisy. In this study, we evaluated the anti-wrinkle effects of CL and investigated bio-markers (e.g ; MMP-1, MMP-3, MMP-9, TIMP-1, type I procollagen) associated with skin wrinkle improvement. We tested the anti-wrinkle effect of CL using human fibroblast called CCD-986Sk cell. We observed an increase in MMPs, TIMP-1, and type 1 pro-collagen CL in CCD-986Sk cells irradiated with UVB at an intensity of $2mJ/cm^2$ for 60 seconds. As a result, CL decreased UVB-induced MMPs levels and mRNA expressions in CCD-986Sk cell. The levels and mRNA expressions of type I procollagen and TIMP-1 were increased by CL. These results suggest that CL has activities on improvement of skin wrinkle, which is induced by UVB radiation. Taken together, this study proposed the possibility of developing herbal medicine and functional herbal cosmetic materials with wrinkle-improving effects of Cuscuta chinensis Lamark.

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.

To identify new active anti-wrinkle ingredients, this study investigated the anti-wrinkle effects of Schizandra chinensis Baillon fermented with Lactobacillus plantarum (SCF) by assessment of cytotoxicity of human dermal fibroblast, collagen biosynthesis, matrix metalloproteinase-I (MMP-1) inhibition and elastase inhibition. S. chinensis was fermented with L. rhamnosus for 1 day at $37^{\circ}C$. The cytotoxicity of SCF was evaluated by a cytopathic effect reduction method. Effects on collagen biosynthesis and matrix metalloproteinase-I (MMP-1) of SCF were evaluated by previous reported method using procollagen type-IC peptide EIA kit and Matrix Metalloproteinase-1 Biotrack activity Assay Kit, respectively. Elastase inhibition assay was conducted by reaction of enzyme and substrate using N-Suc-$(Ala)_3$-nitroanilide as the substrate. As the results, SCF didn't show cytotoxicity against human dermal fibroblast at concentration of $100{\mu}g/mL$. Also, SCF was increased collagen synthesis and showed inhibitory effect of MMP-1 (p < 0.05). In the elastase inhibition assay, the $IC_{50}$ of SCF was $36.4{\mu}g/mL$. Therefore, our results indicated that SCF possesses anti-wrinkle effects and can be used practically for anti-wrinkle care of skin.
