ZAI Xue ming WU Guo rong GONG Zhu nan LU Chang-mei LIU Hua CHENG Jing yao (The College of Life Science, Nanjing Normal University ,Nan jing 210097)  
Anti-oxidant ingredients and total anti-oxidant capacity from Taraxacum mongolicum Hand -Mazz collected in drought and wet environments were studied and their isozymogram from PAGE were compared Results showed that activities of anti-oxidant enzymes ( eg SOD,POD,CAT etc ) and content of Vc from leaves were the highest, with content of soluble sugar, flavonoid and chlorogenic acid from anthotaxies were the highes; activities of SOD,POD and CAT from organs of Taraxacum mongolicum Hand -Mazz in wet environment were higher than from corresponding organs in drought environment,especially from root, the contents of soluble sugar, flavonoid and chlorogenic acid in drought environment were higher than those in wet environment,especially from anthotaxies; No new SOD isozyme band could be induced by drought and wet invironment; total anti-oxidant capacity from Taraxacum mongolicum Hand -Mazz in drought environment was close to those from correspording organs in wet environment
