Determination of Tanshenoside Ⅰ in Taidangshen (Codonopsis pilosula) and Cultivated Ludangshen (C. pilosula) of Different Years Old / 中草药

ABSTRACT

Amounts of tanshenoside Ⅰ in cultivated Ludangshen of different years of cultivation history was determined by TLC densitometry in comparison with that in wildly grown Ludangshen and cultivated Taidangshen. Results showed that tanshenoside Ⅰ in cultivated Ludangshen decreases with increased years of cultivation history while that in cultivated Taidangsihen is slightly lower than that of Ludangshen of the same years of cultivation. Tanshenosde Ⅰ in wild Taidangshen is also lower than that in cultivated Taidangshen
