Attenuating properties of Agastache rugosa leaf extract against ultraviolet-B-induced photoaging via up-regulating glutathione and superoxide dismutase in a human keratinocyte cell line.

Agastache rugosa Kuntze, known as a Korean mint, is an herbal medicine that has been used for the treatment of diverse kinds of symptoms in traditional medicine. This work was undertaken to assess the protective properties of A. rugosa leaves against UV-B-induced photoaging in HaCaT keratinocytes.

Effect of inhibition on tyrosinase and melanogenesis of Agastache rugosa Kuntze by lactic acid bacteria fermentation.

Background: This work presents the first report that A. rugosa could have tyrosinase and melanogenesis inhibition and that its activities also be improved by fermentation with Lactobacillus rhamnosus and Lactobacillus paracasei. It was found that the tyrosinase and melanogenesis inhibition was correlated with antioxidant activity of acacetin, the major biologically active substances in A.

Enhancement of skin anti-inflammatory activities of Scutellaria baicalensis extract using a nanoencapsulation process.

In this study, we sought to increase the anti-inflammatory activity of Scutellaria baicalensis extracts using a nanoencapsulation process. The ethanol extract of Scutellaria baicalensis was encapsulated with lecithin and two other extracts as follows: aqueous extraction at 100 °C for 24 h (AE), 70% ethanol extracts at 80°C for 24 h (EE), which were also compared as controls. The ethanol extract of S.
