    Abstract:
    A high-performance liquid chromatographic method was applied to the determination of gamabufotalin, telocinobufagin, bufotalin, cinobufotalin, bufalin, cinobufagin and resibufogenin in three traditional Chinese medicinal preparations containing ChanSu. The compounds were separated on a YMC-C18 column (250 x 4.6 mm, 5 um) with a gradient of acetonitrile and 0.3% aqueous acetic acid (v/v) at a flow rate of 0.8 mL min(-1) and detected at 296 nm. Complete separation was obtained within 35 min for the seven bufadienolides. The calibration curves showed good linearity (r2 > 0.999) within the test range. The recovery was 95.5% - 105.9%. The assay could simultaneously determine seven major bufadienolides of the three Chinese medicinal preparations of ChanSu in 35 min. The results obtained suggested that the developed HPLC assay could be comprehensively utilized for the quality control of the three traditional Chinese medicinal preparations of ChanSu used in the clinic.
