Abstract:
Objective To investigate the thermostability of aristolochic acid Ⅰand the effect of the compatibility on aristolochic acid Ⅰ in Caulis Aristolochiae Manshuriensis decoction and to explore the detoxification mechanism of compatibility for aristolochic acid Ⅰ.Methods Analyzing the contents of aristolochic acid Ⅰ by HPLC in the single decoction of Caulis Aristolochiae Manshuriensis,the concoction of Caulis Aristolochiae Manshuriensis with Cortex Moutan,the residues of decocted Caulis Aristolochiae Manshuriensis and the residues of concocted Caulis Aristolochiae Manshuriensis with Cortex Moutan,respectively.Results Aristolochic acid Ⅰ decreased after heating in pure water,a new peak was found in HPLC spectra and supposed to be the derivate of aristolochic acid Ⅰ,which was also found in the decoction of Caulis Aristolochiae Manshuriensis.The content of aristolochic acid Ⅰ in the concoction of Cortex Moutan with Caulis Aristolochiae Manshuriensis is lower than that in the single Caulis Aristolochiae Manshuriensis decoction.Furthermore,the quantity of aristolochic acid Ⅰ in the residues of Caulis Aristolochiae Manshuriensis after concoction is lower than that in the residues of single Caulis Aristolochiae Manshuriensis decoction.Conclusion Aristolochic acid Ⅰ is unstable in decoction and a part of it was changed into another compound.The stripping of aristolochic acid Ⅰfrom Caulis Aristolochiae Manshuriensis is not inhibited when Cortex Moutan concocted with Caulis Aristolochiae Manshuriensis.It is the chemical reaction of aristolochic acid Ⅰ,which could decrease the toxicity in the decoction or concoction of Caulis Aristolochiae Manshuriensis.
