Radical species released from soybean roots were trapped by spin trapping reagents such as DEPMPO and DBPMPO. The trapped radicals were carbon-centered radicals from their hyperfine coupling constants (aH = 2.15, aN = 1.48, aP =4.60 mT). Based on the decline rate of the signal intensity, three radical species with different half-lives were observed. The radical species were separated by HPLC and identified.

用DEPMPO和DBPMPO等自旋捕集剂捕集大豆根系释放的自由基。从它们的超精细耦合常数（aH = 2.15，aN = 1.48，aP =4.60 mT）来看，被捕获的自由基是碳中心自由基。基于信号强度的下降速率，观察到具有不同半衰期的三种自由基物种。自由基物种通过HPLC分离并鉴定。
