Trapa japonica, commonly known as “water nut” or “water chestnut”, is an annual aquatic plant. The fruit of T. japonica, known as Neungin (菱仁) or Neungsil (菱實), is edible and is used for detoxification of stomach cancer in private and oriental medicine. This study was conducted in order to examine the anti-wrinkle, whitening, and antioxidant activities of T. japonica floating part as a cosmeceuticals, viz. EF; 70% ethanol extract, WF; water extract, HWF; hot water extract. The highest content of total flavonoid compounds was 40.04 mg·QC/g at HWF. The polyphenol compound content was the highest by 166.78 mg·TA/g in WF. As a result of the analysis of anti- aging effect at 2,000 ug/mL, collagenase and tyrosinase inhibition activities showed the highest activity of 57.09% and 50.74% in HWF, respectively. The astringent effect and xanthine oxidase inhibition were highest at 38.27% and 38.00% in WF. The ABTS radical scavenging ability of 500 ug/mL, WF and HWF was more than 98%. More than 90% of DPPH radical scavenging ability at 2,000 ug/mL was observed for all extracts. The SOD-like activity showed the highest activity with EF of 46.25% at 500 ug/mL, however activity decreased as the concentration increased. In RAW264.7 macrophages, HWF decreased by approximately 30% at a concentration of 50 ug/mL or higher, and WF was also decreased by 20% at 100 ug/mL. Compared to the LPS-treated group, NO production was reduced by WF and HWF by approximately 23% at a concentration of over 25 ug/mL. According to these results, T. japonica floating parts differ depending on the extraction solvent and method, and because of its excellent anti-wrinkle, whitening, astringent effect, and antioxidant effect, extract from T. japonica floating parts is useful for extraction of water-soluble solvent. In addition, T. japonica floating parts is believed to be a natural resource that can be used as a cosmeceutical material.
