Determination of syringin and rutin in 11 species of Saussurea by high performance liquid chromatography

Zorbax ODS column and gradient elution of acetonitrile acetic acid solution as mobile phase were employed to determine the content of syringin and rutin in 11 species of Saussurea by RP_HPLC. The detection wavelength was 260 nm. The results showed that standard curves of syringin and rutin were linear in the range of 0.052?5 μg 1.05 μg and 0.065?8 μg 1.32 μg, respectively. The correlation coefficients were 0.998?8 and 0.999?9. The method provides new indices for quality control of Saussurea .
