Abstract
Adenophora stenanthina (Ledeb.) Kitag is a raw material for mongolian medicine and is cultured in different fields across China. To ensure the quality of the Adenophora stenanthina (Ledeb.) Kitag, we determined the concentration of heavy metals (copper, lead and cadmium), moisture, general ash and acid-insoluble ash content in Adenophora stenanthina (Ledeb.) Kitag in eight samples from different geographical regions in China, according to the WHO guidelines on the good agricutural practices (GAPS). Adenophora stenanthina (Ledeb.) Kitag was prepared by nitric acid: hydrochloric acid (4: 1) solution. The cadmium and lead content were determined by graphite furnace atomic absorption spectrometry; copper content was determined by flame atomic absorption method. Pb concentrations in the samples from Nai Man and Chen Ba Er Hu were higher than GAPS guidelines. Cd concentrations in the samples from Ku Lun, A Ba Ga and Chen Ba Er Hu were higher than GAPS guidelines; concentrations of acid-insoluble ash in samples from E Wen Ke and A Ba Ga were higher than GAPS guidelines; moisture, general ash content of the eight samples are all in the normal range. To sum, the results indicate that, for the safety of clinical usage of Adenophora stenanthina (Ledeb.) Kitag, it is not recommended to collect medicinal herbs from areas in Nai Man, Chen Ba Er Hu, Ku Lun, E Wen Ke and A Ba Ga.
