To establish a method using vortex-assisted cloud point extraction for four pennogenin Ingredients of Paris polyphylla Sm., taking nonionic surfactant primary alcobol ethoxylate (AEO -9)as the extractant,using a mixture of acetonitrile-water (38 ∶62,by volume)as the mobile phase,the enrichment Pennogenin Ingredients was rapid performed by high performance liquid chromatography (HPLC).Under the optimized conditions,the volume of AEO -9 was 110 μL,the volume of n-Valerate was 150 μL,pH was 9.0,the equilibration time and temperature were 40 ℃ and 15 min,respectively.The result shows that the contents of four Pennogenin Ingredients of Paris polyphylla Sm.VI,VII,Pa and H were 0.992 3%,1.360 3%,3.344 4% and 1.666 3%,respectively.The detection of limits (LOD)was 3.2—4.0 μg/L;the relative standard deviations (RSD)was below 0.5% (n =9 );the limit of quantification (LOQ)was 6.6—8.3 μg/L;the linear range was 10—500 μg/L;the enrichment factor was 23 and the relative recoveries was ranged from 98.68% to 102.46%.
