Abstract
OBJECTIVE: To determine sarsasapogenin in Anemarrhena asphodeloides. METHOD: Chloromethane extract (1 microliter) with cholesterol as internal standard was analyzed on HP-1 column, operated at 270 degrees C with N2 as carrier gas and FID. RESULT: The method was linear within the range of 0.245-2.94 micrograms.microliter-1, with a correlation coefficient of 0.9996. The average recovery was 95.52% +/- 1.77%, CONCLUSION: The method is reproducible, rapid and sensitive.
