title: [Dynamic study on two lignans contents in different parts of Sinopodophyllum hexandrum].
abstract: The contents of two lignans, namely 4'-demethylpodophyllotoxin and podophyllotoxin in cultivated and wild Sinopodophyllum hexandrum plants were extracted by ultrasonicaction and determined by HPLC. According to the result showed, the order of parts of cultivated plants containing 4'-demethylpodophyllotoxin from high to low is as follows: stem > root, no 4'-demethypodophyllotoxin was detected in leaves of cultivated plants; The order of parts of wild plants 4'-demethylpodophyllotoxin from high to low is as follows: lateral root > petiole > rhizome > leaf, no 4'-demethypodophyllotoxin was detected in fruit. The order of parts of cultivated and wild S. hexandrum containing podophyllotoxin from high to low is as follows: root > petiole > leaf ( > fruit). Both of the lignan contents in different parts of cultivated plant varied in a " W" curve with the changes in seasons, with the highest content in July.
