【摘要】 目的 :建立儿童Ⅱ号口服液 (黄柏、龙胆草、知母等 )中龙胆苦苷 ,盐酸巴马汀及盐酸小檗碱高效液相色谱测定方法。方法 :以DiamonsilTM C18柱 ( 2 5 0mm× 4 .6mm ,5 μm)为色谱柱 ,以乙腈 磷酸 三乙胺 水为流动相 ,检测波长为 2 70nm ,流速为 1mL·min-1。结果 :龙胆苦苷 ,盐酸巴马汀及盐酸小檗碱的线性范围分别为 72 .8～ 72 8μg·mL-1(r =0 .9998) ,7.5 5～75 .5 μg·mL-1(r =0 .9998) ,12 .4 5～ 12 4 .5 μg·mL-1(r =0 .9999) ,平均加样回收率 (n =6 )分别为 98.17% ,98.78% ,98.6 0 % ;RSD分别为 1.6 0 % ,1.35 % ,1.2 5 %。结论 :该方法准确 ,重复性好 ,专属性好 ,适合于儿童Ⅱ号的质量控制。更多还原

【Abstract】 AIM: To establish the method for determination of gentiopicrin, palmatine hydrochloride and berberine hydrochloride in Ertong Ⅱ Oral Liquid (Cortex Phellodendri, Radix Gentianae, Rhizoma Anemarrhenae, etc.) by RP HPLC. METHODS: The column was a Diamonsil TM C 18 column (250mm×4.6mm, 5μm); the mobile phase was CH 3CN H 3PO 4 C 6H 15 N H 2O; The ultraviolet detection was set at 270nm; the flow rate was 1mL·min -1 . RESULTS: The linear ranges of gentiopicrin, palmatine hydrochloride and berberine hydrochloride were 72.8～728μg·mL -1 ( r=0.9998 ), 7.55～75.5μg·mL -1 ( r=0.9998 ), 12.45～124.5μg·mL -1 ( r = 0.9999 ), respectively. The average recoveries ( n =6) of gentiopicrin, palmatine hydrochloride and berberine hydrochloride were 98.17%, 98.78%, 98.60%; RSD were 1.60%, 1.35%, 1.25%, respectively. CONCLUSION: The method is accurate, reproducible and highly selective, thus suitable for quality control of Er Tong Ⅱ Oral Liqual.更多还原
