Objectives : Gardeniae Fructus extract is used as a component of various cosmetics. However, the effect of the extract on the motility of keratinocytes has not been studied. The aim of this study is to investigate the inhibitory effect of ethanol extract of Gardeniae Fructus (GFET) or ethyl acetate extract of Gardeniae Fructus (GFEA) on oxidation and motility of human keratinocyte HaCaT cells.
Methods : Antioxidant activity of Gardeniae Fructus extracts were determined by the 2,2'-azino-bis-3- ethylbenzothiazoline-6-sulphonic acid (ABTS) assay. To investigate the cytotoxicity of Gardeniae Fructus extracts, 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) assay was performed. The mRNA expression levels of tight junction related genes were analyzed using quantitative RT-PCR analysis. Cell migration assay was employed to determine the activity of Gardeniae Fructus extracts on motility of human keratinocyte HaCaT cells.
Results : GFET and GFEA showed strong antioxidant activity. GFEA showed stronger cytotoxicity in HaCaT cells than GFET until 2.0 ㎎/㎖ concentration. Cell migration assay demonstrated thatObjectives : Gardeniae Fructus extract is used as a component of various cosmetics.

GFEA showed stronger cytotoxicity in HaCaT cells than GFET until 2.0 ㎎/㎖ concentration. Cell migration assay demonstrated that GFET and GFEA decreased the motility of HaCaT cells. In addition, the mRNA expression level of claudin 8 among tight junction genes was significantly reduced by GFET or GFEA treatment.
Conclusions : We investigated the physiological activities of the extracts of Gardeniae Fructus extracts on human keratinocytes by two different extraction methods. In addition, the mRNA expression level of claudin 8 among tight junction genes was significantly reduced by either GFET or GFEA treatment. This study provides basic information on the application of Gardeniae Fructus extract to cosmetics component.
