To establish a quantitative analysis method of the triterpenoid saponins in Cy-athula officinalis. Methods: An HPLC-ELSD method was used to determine the contents of two major triterpenoid saponins in C. officinalis. The separation was performed on a Shim-pack VP-ODS column (C18, 5μm, 4.6 mm×250 mm), with a mixture solution of acetonitrile-0.1% formic acid in water (37∶63) as mobile phase. The flow rate was 1.0 mL·min-1. The drift tube temperature of ELSD detector was 105℃, the gas flow was 2.8 L·min-1. Results: The contents of 3-O-{β-D-glucopy- ranosyl-(1→2)-[α-L-rhamnopyanosyl-(1→3)]-(β-D-glucuronopyranosyl)}-28-O-β-D-glucopyranosyl oleanolic acid (cyaonoside A) and 3-O-α-L-rhamnopyranosyl-(1→3)- β-D-glucuronopyranosyl-28-O-β-D-glucopyranosyl oleanolic acid (cyaonoside B) were 0.47%~1.37% and 0.46%~1.32%, respectively. The linear range of were 1.0~20.0μg and 0.8~16.0μg and the average recoveries were 99.72% and 97.72%, respectively. Conclusion: The HPLC-ELSD method is accurate and suitable for the quantitative analysis of these two saponins in C. officinalis.
