摘  要:
This paper described the method of assaying the contents of quinocetone in raw materials & its preparation by RP-HPLC. By using Symmetry C 18 as solid phase and methanol-water (60∶40) as mobile phase, and detecting at 314 nm, the standard curves for quinocetone were linear in the range of 0.05~0.25 mg/mL (r=0.999 3,n=5), and the average recovery was 98.89% with RSD=1.13%(n=5). The method is simple, fast and useful for the determination of quinocetone and its preparation.
