摘　　要：以四种银耳属真菌为研究对象，采用水提法和酸提法，从中获得多个粗提取物，并对其进行抗氧化活性研究。经过超氧自由基实验、羟自由基实验和DPPH实验后，发现来自血耳的两种提取物TSPA和TSPW展现出较高的羟自由基和超氧自由基清除活性，其活性甚至大于VC，TSPA也表现出DPPH清除能力，可以作为潜在的抗氧化剂开发。Several products were extracted from four fungi of TremeUa by boiling-water extraction and acid isolation. On the basis of superoxide radical assay, hydroxyl radical assay and DPPH assay,their antioxidant activity were investigated. Two extracts TSPA and TSPW from TremeUa samguinea Peng exhibit the higher scavenging activity of hydroxyl radical and superoxide radical than Vc,TSPA has a scavenging activity of DPPH,and they can be explored as potential antioxidants.
