Abstract

Aristolochic acid (AA) included in the plants Aristolochiaceae have been well known to be nephrotoxic and carcinogenic inducer and to cause renal disease such as Chinese Herb Nephropathy (CHN). In this study, we used a high performance liquid chromatopaphy-mass spectrometry (HPLC-MS) under the positive ion detection mode for the quantitative change of aristolochic acid-I and-II (AA-I and AA-II) in Aristolochiaceae (Aristolochia contorta Bunge, Aristolochia debilis Sieb. et Zucc., Aristolochia fangchi Wu), some related plants (Cocculus trilobus De candolle, Inula helenium Linne, Saussurea lappa Clarke), and its prescriptions (防己茯笭湯, 定喘散) with or without processing. Here, the processing methods and prescriptions in oriental medicine were generally used to alleviate toxicity or alter property of herbal medicines. However, the concentrations of AA-I and AA-II were highly determined in processed material extracts rather than unprocessed those, not measured in some related plants. Also, the concentrations of AA-I and AA-II even at the prescriptions mixed the plants of Aristolochiaceae were detected to range from 0.73 to 2.53 ppm. Thus, the present results suggest that the content of AA-I and AA-II contained to plants of Aristolochiaceae was not reduced by the processing methods or prescriptions which can induce the physico-chemical change and pharmacological transformation in traditional herbal medicines.
