In order to investigate the possibility of Sesamum indicum L. (S. indicum) extract as an active ingredient for wrinkle-care cosmetics, we prepared 70% ethanolic extract of S. indicum and measured its elastase inhibitory activity and collagenase inhibitory activity. We also evaluated the effect of S. indicum extract on protein and mRNA expression of MMPs in fibroblast cell (CCD-986sk). For anti-wrinkle effects, elastase inhibition activities and collagenase inhibition activities were 37.8% and 45% at a dose of $1,000{\mu}g/mL$ of S. indicum 70% ethanol extract. For a cell viability test, measured on fibroblast cell by ethanol extract of S. indicum, results showed 96% with cell viability at $100{\mu}g/mL$ concentration. According to the results of western blot of ethanol extract from S. indicum the expression of the matrix metalloproteinase-1 (MMP-1), matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-3 (MMP-3) protein was decreased by 63%, 43%, 49% at $100{\mu}g/mL$ concentration. Reverse transcription-polymerase chain reaction (PCR) of ethanol extract from S. indicum showed that the expression of MMP-1, MMP-2, MMP-3 mRNA was decreased by 82%, 79%, 82% at $100{\mu}g/mL$ concentration. The findings suggest that 70% ethanol extract from S. indicum has potential as a cosmeceutical ingredient with anti-wrinkle effects.

Objectives : Fine dust caused by environmental pollution cause oxidative damage and skin aging. In this study, The possibility of using the Codium fragile extract (CFE) as an anti-aging product for skin improvement was evaluated by confirming the protective effect of skin cells from PM10 (particulate matter 10) through inhibition of ROS and MMPs. Methods : In this study, elastase and collagenase inhibitory activities were evaluated. Cell viability was evaluated by treating keratinocytes (HaCaT cell line) with CFE at various concentrations. The cytoprotective effect from PM10 in keratinocyteswas evaluated using the 3-[4,5-dimethylthiazol]-2-yl]-2,5-diphenyl-tetrazoliumbromide (MTT) assay. ROS (reactive oxygen species) was measured in keratinocytes damaged by PM10 using DCF-DA (2′,7′-dichlorofluorescin diacetate) fluorescence staining. As an anti-aging effect of CFE, MMP-1 (matrix metalloproteinase-1) and MMP-1 (matrix metalloproteinase-9) inhibitory activities were evaluated. Results : As a result, CFE decreased the activity of elastase and collagenase. As a result of evaluating the toxicity of CFE, it is non-toxic at a concentration of 10 to 80 ㎍/㎖. Although cell viability of HaCaT cells treated with PM10 decreased, cell viability increased by 38% when treated with CFE 80 ㎍/㎖. Also, ROS decreased by 8.4%, and MMP-1 and MMP-9 decreased at CFE 80 ㎍/㎖. Conclusions : CFE showed excellent cell protection effect, and it is considered that it can be used in anti-aging products for skin improvement by effectively inhibiting ROS and MMPs from keratinocyte damage caused by fine dust.

Cnidium japonicum a biennial plant belonging to the family Umbelliferae, is a halophyte that grows in high-salinity areas of coastal sand dunes and sandy shores. This study was conducted to investigate the constituents, antioxidant activities, and physiological activities of C. japonicum. Mineral analyses revealed that potassium, sodium, calcium, and magnesium were the most prevalent minerals in C. japonicum. We used 80% ethanol, 80% methanol, and distilled water as solvents to prepare extracts from C. japonicum tissues, and the obtained extraction yields ranged between approximately 26% and 32%. Among the three extracts, the ethanol and methanol extracts had higher total polyphenol and flavonoid levels than the water extracts did. The antioxidant activities of methanol extracts were the highest among the various solvent extracts of C. japonicum as was the elastase/collagenase inhibitory activity. In contrast, the ethanol extract exhibited the highest tyrosinase inhibitory activity. Furthermore, the methanol extract possessed over 80% BACE1 (β-secretase) inhibitory activity at a final concentration of 20 ㎍/mL. Therefore, these results indicate that methanol and ethanol extracts of C. japonicum may be useful as antioxidant and functional substances in food and pharmaceutical material.
