We tried to check the antioxidant activity and toxicity of trichosanthis cucumeroidis radix extracts in skin cells, and check the possibility of their use as a functional material that can be effectively used on the skin. Total polyphenol and total flavonoid content, which are indicators of antioxidant activity of trichosanthis cucumeroidis radix extracts, were confirmed, and cytotoxicity was confirmed using Neutral red assay in the skin. As a result of the study, the content of total polyphenols and total flavonoids increased concentration-dependent. High survival rates in fibroblast HDF cells were identified, and cell survival rates were significantly lowered from 5 ㎍/mL in melanocytes B16F10 melanoma cells and inflammation-related macrophages RAW 264.7 cells. He results of this study are believed to be available as basic data for antioxidant activity of trichosanthis cucumeroidis radix extracts and skin cells.

In this study, the physiological activity effect of trichosanthis cucumeroidis radix extract on antioxidant activity, whitening, and anti-inflammatory activity was checked, and the possibility of its use as a functional material was checked. The purpose of this study was to confirm the antioxidant activity through DPPH radical scavenging activity of trichosanthis cucumeroidis radix extract, whitening activity effect through melanin production inhibition ability for melanin cell B16F10 melanoma cell, and anti-inflammatory activity effect through NO production inhibition ability for macrophage RAW 264.7 cell. As a result of the study, the concentration-dependent DPPH radical scavenging activity of the trichosanthis cucumeroidis radix extract was confirmed, and DPPH radical scavenging activity similar to that of the positive control Ascorbic acid was confirmed. It was confirmed that the melanin production inhibitory activity induced by 100 nM 𝛼-MSH and the NO production inhibitory ability induced by LPS 1 ㎍/mL were significantly suppressed. Accordingly, it is considered that the trichosanthis cucumeroidis radix extract may be used as a functional material having antioxidant, whitening, and anti-inflammatory effects.
