A quantitative metbd for the determination oh the pueraria content in Xinanning Pian was established. The sampe was extracted with alcohol by reflux in a water bath. The resolution of pueraria and the adjacent peak was 1.5 as determined by RP-HPLC. The number of theoretical plates calculated by pueraria peak was 1510.The standard curve was linear in the range of 0.264~2.640 μg and the correlation coefficient was 0.9999.The average recovery was 100.7%. The method is simple and accurate and thus is satisfactory for the determianation of the pueraria content in Xinanning Pian
