Antioxidant activity and cell toxicity of pressurised liquid extracts from 20 selected plant species in Jeju, Korea
چکیده انگلیسی

Twenty plant species were selected from Jeju, Korea, and extracts made using a pressurised liquid extraction system. Integral antioxidative capacity (IAC), inhibitory activity of nitric oxide (NO) production, and cell toxicity were evaluated to identify new dietary antioxidants of natural origin with a low degree of cell toxicity. Geranium thunbergii and Pyrrosia lingua showed high IAC values of water-soluble substances (9.76 and 9.48 mmol ascorbic acid equivalents/g), with high IAC values of lipid-soluble substances of 5.20 and 1.97 mmol trolox equivalents/g, respectively. Prunus padus and Rhus javanica did not show any cytotoxicity on RAW 264.7 macrophages or HS-68 normal skin fibroblast cells and showed inhibitory activity of NO production (IC50 = 327 and 337 μg/ml) with LPS-induced RAW 264.7 macrophages. Malus sieboldii did not exhibit cytotoxicity with either cell type and showed high inhibitory activity of NO production (IC50 = 219 μg/ml) and high IAC values of water-soluble substances (4.93 mmol ascorbic acid equivalents/g).
