【Abstract】 A RP HPLC method for the determination of andrographolide and 14 deoxy 11,12 didehydroandrographolide in Houshuning tablets was established. A Diamonsil C 18 column was used, with the mobile phase of methanol water(70∶30). The flowing rate was 1.0ml/min, and the detection wavelength was 225nm. The average recoveries of andrographolide and 14 deoxy 11,12 didehydroandrographolide were 97.0%( RSD 1.2%) and 94.6% ( RSD 0.8%), respectively. 更多还原 【关键词】 喉舒宁片; 穿心莲内酯; 脱水穿心莲内酯; 反相高效液相色谱; 测定; 【Key words】 Houshuning tablets; andrographolide; 14 deoxy 11,12 didehydroandrographolide; RP HPLC; determination;
