The aim of this study was to examine the possible antioxidant and antiproliferative activities of the ethanol and water extracts of four Hydrocotyle species from Taiwan. ABTS radical monocation scavenging, FRAP method, DPPH radical scavenging, reducing power method, total polyphenol content, total The results showed that the water extracts of all the samples had higher antioxidant and antiproliferative activities than the ethanol extracts.

本实验针对台湾产四种天胡荽属植物之水萃取物及乙醇萃取物进行抗氧化及抗增生活性研究，分析方法包括ABTS自由基的清除、FRAP方法、DPPH自由基的清除、还原力、总多酚类含量、总类黄酮类含量、总黄酮醇类含量以及癌细胞增生之抑制，结果显示所有样品的水萃取物之抗氧化及抗增生活性皆大於乙醇萃取物，但在抗氧化活性方面，所有受测样品活性皆小於正对照组。

Adopt poaching and alcohol sinking to get coarse polysaccharide, then take MCP, MCP-1 and MCP-2 for studing in antioxidation activities. They have strong ability for scavenging free radical only in DPPH system and oxidation system of linolic acid induced by alkane radical, but negatively in hydroxyl system and in super-oxygen anions system. And MCP-2 is better than MCP-1, so we choose enzymolysis method to remove protein.
