槟榔花茶清除 DPPH 自由基能力研究
Study on Scavenging Ability of Areca Inflorescence Tea on DPPH Radical
摘要
Abstract
The active substances from areca inflorescence tea were extracted respectively by using accelerated solvent extraction (ASE) technique and heating reflux (HR) method with different solvents , and the scavenging abilities of these extracts on DPPH radical were studied .The results showed that the scavenging abilities of different extracts on DPPH free radical had the following se -quence:vitamin c ( Vc) >BHT>ASE-EtOAC>ASE-MeOH>HR-EtOAC>HR-MeOH>ASE-H2 O>ASE-MSO>HR-H2 O>HR-MSO, and their IC50 values were 10.1365, 44.4007, 113.2, 159.7, 184.0, 207.7, 246.4, 258.5, 317.7 and 950.6 μg/mL respectively.The results indicated that the extracts from areca inflorescence tea had a certain ability to scavenge DP -PH free radical.The scavenging capacity was the best when acetic ether was used as the extraction solvent .In comparison with HR method, ASE method was more helpful to extracting the active substances from areca inflorescence tea .关键词
