To improve the quality standard for Compound Luotuopengzi Ointments(Semen Pegani,Se-men Hyoscyami,Colchicum autumnale).METHODS:Semen Pegani and Semen Hyoscyami were identified by TLC.The HPLC-quantitative analysis was carried out on a column of Phenomenex Luna C18(5 μm,250 mm ×4.6 mm ID),atropine and scopolamine were determined using methol-water(20 ∶ 80,the water solution contained 0.02 mmoL/L of sodium acetate,0.2 mL/L of triethylamine,4 mL/L of tetrahydrofuran and adjusted to pH 6.0 with acetic acid) as the mobile phase with UV detection at 210 nm.Colchicine was determined using methanol-0.05 moL/L potassium dihydrogen phosphate(45 ∶ 55) as the mobile phase with UV detection at 350 nm.RESULTS:The linear ranges of atropine,scopolamine and colcihcine were in the ranges of 0.131 6-1.316 μg(r =0.999 8),0.063 6-0.636 μg(r =0.999 8),and 0.081 76-0.817 6 μg(r =0.999 6),respectively.The average recove-ries of atropine,scopolamine and colchicine were 97.6%,97.7% and 96.3%,respectively.CONCLUSION:The identification and assay methods are simple,accurate,exclusive and with good reproducibility.The improved quality standards can be used to control the quality of this product effectively.
