Abstract: Objective:To establish a two-dimensional liquid chromatography method for the determination of six active substances including uracil, uridine, adenosine, adenine, guanosine and ergosterol in fermentative cordycepic fungal powder(Cs-4). Methods:The samples were extracted with acetonitrile solution and filtered. After injection, 5 nucleosides and bases were separated and determined in the first dimensional liquid phase system, and ergosterol was determined in the second dimensional liquid phase system. Results: In the method the Linear range of uracil, uridine,adenosine,adenine,guanosine,and ergosterol is 0.3-30 μg·mL-1, 0.4-40 μg·mL-1, 0.8-80 μg·mL-1, 1.0-100 μg·mL-1, 2.5-250 μg·mL-11.5-150 μg·mL-1. The recovery and RSD of uracil, uridine, adenosine,adenine,guanosine and ergosterol are 96.7%-103.4% and 1.8%-3.1%,98.9%-101.4% and 1.7%-2.6%,95.9%-104.7% and 1.5%-3.5%, 97.0%-104.0% and 1.4%-4.0%, 98.2%-101.4% and 1.9%-3.1%, 96.0%-102.0% and 2.5%-3.7%. Conclusion: The method significantly improved the analysis efficiency and accuracy, and could meet the needs of drug evaluation and quality supervision.The method is of great significance for the development of separation method for complex components of fermentative cordycepic fungal powder(Cs-4) and guiding clinical use.
