The results showed that there was a good linearity between the concentration of spinosin,6-feruloylspinolin in the flavones reference extract and the peak area value in ranges of 0.0087~0.4366(r=0.9996),0.0039~0.1952 mg·mL^-1(r=0.9996),respectively. The average recoveries of two components were 100.26%,100.90% with RSDs which were 2.45%,1.37%. The results of 12 batches of Zaoren Anshen granules were determined by utilizing the reference extract of Semen Zizipon seed as control,which were basically consistent with those obtained by single reference substance.
