Effects of Ginger Phenylpropanoids and Quercetin on Nrf2-ARE Pathway in Human BJ Fibroblasts and HaCaT Keratinocytes

Figure 1

UHPLC-MS analyses of ginger methanol extract. (a), (b), and (c) are HPLC-PDA chromatograms of ginger methanol extract at 370, 280, and 230 nm, respectively. (d) is a Sum HPLC-PDA chromatogram in interval (230–370 nm) detected wavelength. All of the compounds were detected in negative ion mode ionization. Peaks with the identified phenylpropanoids are listed in Table 1. AU denotes absorbance units.
