| Abstract: | Objective: To determine the content of hypoxanthine in Pheretima aspergillum from different habitats. Method: A RP-HPLC method was established. The chromatographic column was Inertsil ODS-EP. The mobile phase was H2O-CH3OH-C4H8O(93: : 7: 0. 05 ). The flow rate was 1. 0 ml/min, and the detection wavelength was 254 nm. Results: The average recoveries for hypoxanthine was 98. 6% , precision of the method was 0. 50% ( RSD, n = 6). Conclusion: The method can be used to determine the content of hypoxanthine in Pheretima aspergillum from diffrent habitats. |
