Abstract: Objective To choice the distilling condition of astragaloside in nasal sinusitis dripping pills(NSDP). Methods In-vestigating the influence of the four condition (including water volume, distilling times, concentration for ethanel precipitation and time of decoction) by adopting orthogonal design method, using the withdraw rate of astragaloside A as a main evaluation standard. The content of astragaloside A in NSDP was determined by HPLC. The mobile phase was acetonitrile:0.1% phosphoric acid(33:67)and detected on DELTA-PAK C18 column at the wavelength of 201nm. ResultsThe regression equation within the spotted range of 0.044-0.440mg/mL was A=69633.018V+1290.434 with good linearity, r=0.9998. The average recovery rate was 92.58% and RSD=1.50%(n = 5). Conclusion The experiment result prove that the way is intelligent, accurate, specific, reliable, stability, precise, which is suitable for the quality control of NSDP. And we obtain the best technical process of NSDP with orthogonal design.
