- Abstract: OBJECTIVE: To establish a quantitative method for determining the contents of uracil, cytidine, hypoxanthine, xanthine, uridine, inosine, and guanosine in Holotrichia diomphalia Larvae by HPLC. METHODS: The HPLC analysis was performed on Waters HSS T3 column(4.6 mm×250 mm, 5 μm). The mobile phase was composed of acetonitrile(A) and water(B), and gradient elution was carried out. The flow rate was 1.0 mL•min-1. The column temperature was maintained at 30 ℃. The detection wavelength was 260 nm. RESULTS: The correlation coefficients of the seven components ranged from 0.999 1 to 1.000 0. The average recovery rates(n=6) were between 91.2% and 97.4%, and the RSDs were between 1.5% and 2.3%. CONCLUSION: The proposed method is simple, accurate and reliable, thus providing basis for comprehensive quality control of Holotrichia diomphalia Larvae.
