【摘要】 采用化学发光法 ,考察了人参 (PanaxginsengC .A .Mey)毛状根培养过程中对 3种重要活性氧ROS(O2÷、OH·、H2 O2 )清除能力的动态变化 ,发现在毛状根生长对数期时对 3种ROS都有很强的清除能力 ,而在生长停滞期较低 ,符合人参毛状根生长的S型曲线 ,印证了人参毛状根的生长和衰老过程。更多还原

【Abstract】 Dynamic changes of scavenging reactive oxygen species ROS (O\-\{2\}\+\{÷\}?OH·?H\-\{2\}O\-\{2\}) in hairy root of \%Panax ginseng \%C. A. Mey (HRPG) were studied during its culture process by luminescence. The results showed that HRPG has significant scavenging effect on ROS at the logarithmic multiplication phase but the effect decreased after the logarithmic multiplication phase. The results coincide with growth ’S’ curve of HRPG and show growth and aging process of HRPG.更多还原
