ChanSu (toad venom) is a traditional Chinese medicine for the treatment of serious liver and gastric cancers. The major cytotoxic compounds in ChanSu are bufadienolides. In this paper, a strategy combining qualitative LC/MS analysis and quantitative HPLC determination of major bufadienolides was used for global quality control of ChanSu crude drug. Majority of the bufadienolides in methanol extract of ChanSu were unambiguously characterized by high-performance liquid chromatography coupled with atmospheric pressure chemical ionization tandem mass spectrometry (HPLC/APCI-MS/MS), and by comparing with pure compounds. In addition, eight major bufadienolides were simultaneously determined in one single HPLC run within 30 min with photodiode array detection (DAD). All compounds showed good linearity in a wide concentration range, and their limits of detection (LOD) were around 1 ng. Thus, > 95% of the bufadienolides in ChanSu could be characterized, and > 90% of them were quantitated. The established method is rapid, simple and sensitive, and could be used for the routine analysis of ChanSu crude drug and its preparations. This research sets a good example for the comprehensive quality control of traditional medicine.
