摘　　要：Podophyllotoxin,picropodophyllotoxin and their eight esters were studied using EI MS.The 2-epimers of podophyllotoxin and its esters can be identified by calculating the rate of relative abundance of m/z 168,396 to molecular ion peak in EI MS.Podophyllotoxin,picropodophyllotoxin and their eight esters were studied using EI MS.The 2-epimers of podophyllotoxin and its esters can be identified by calculating the rate of relative abundance of m/z 168,396 to molecular ion peak in EI MS.
