Quantitative Determination and Toxicity Evaluation of Aristolochic Acid Analogues in Asarum heterotropoides F. Schmidt (Xixin) and Traditional Chinese Patent Medicines
Asarum (Xixin), which contains analogues of aristolochic acid (AA), is the only species of the genus Aristolochia included in the Chinese Pharmacopoeia 2020. However, the contents and nephrotoxic effects of AA analogs in Asarum (Xixin) and its formulations have not been clarified. An automatic, effe...

An automatic, effective solid phase extraction process and UPLC-MS/MS method were established for the pretreatment and quantitative detection of AA analogues in commercially available traditional Chinese patent medicines.

The levels of AA analogues were in the nanogram-per-gram level in the main traditional Chinese patent medicines.

Asarum (Xixin), which contains analogues of aristolochic acid (AA), is the only species of the genus Aristolochia included in the Chinese Pharmacopoeia 2020.
