Abstract:
Objective To establish a UPLC method for the simultaneous determination of uracil, adenosine, guanosine, and uridine in Aconiti Lateralis Radix Praeparata (ALRP) and Aconiti Radix (AR), and to compare the content difference of four nucleosides in the samples based on multivariate statistical analysis. Methods Nucleosides in ALRP and AR were extracted with purified water by ultrasonic extraction. The UPLC method was performed on a BEH C18 (100 mm × 2.1 mm, 1.7 μm) through a gradient elution of acetonitrile and water at a flow rate of 0.2 mL/min with column temperature at 30 ℃. The injection volume was set at 4.0 μL, and the detection wavelength was set at 260 nm. Difference significance analysis, hierarchical cluster heatmap analysis, principal component analysis, and TOPSIS analysis were used for data processing to comprehensively evaluate the quality of ALRP and AR. Results The method was in accordance with the regulations, the quantitative evaluation of uracil, adenosine, guanosine, and uridine was in good linear range (r2 > 0.999 3), and the average recovery was 99.86%, 99.14%, 99.74%, and 98.71% respectively, and the RSDs were all less than 2.0%. Taking the four nucleosides as indexes, the samples No. 18 of ALRP and the samples No. 23 of AR were the best in quality. Conclusion The established method is simple, accurate, and reliable with good precision, repeatability, and stability, which can be used for the simultaneous determination of four nucleosides in ALRP and AR, and it might provide the scientific basis for the study of water-soluble constituents in ALRP and AR.
