采用反相高效液相色谱外标法,对复方头孢氨苄胶囊溶出度进行考察。方法:采用转蓝法,以4%乙酸溶液为溶剂,转速为100 r/min,时间为45 min。色谱条件:C18反相色谱柱为固定相,V(水)∶V(甲醇)∶V(3.86%乙酸钠溶液)∶V(4%乙酸溶液)=742:240:15:3为流动相,流速为1.2 mL/min,紫外检测波长为254 nm,在此条件下头孢氨苄和甲氧苄啶两组分能很好地分离。本法的线性范围分别是头孢氨苄为:27.6~276 μg/mL,甲氧苄啶为:5.56~55.6 μg/mL,平均回收率为头孢氨苄:99.32%,RSD=0.78%;甲氧苄啶:100.1%, RSD=0.57%。
採用反相高效液相色譜外標法,對複方頭孢氨芐膠囊溶齣度進行攷察。方法:採用轉藍法,以4%乙痠溶液為溶劑,轉速為100 r/min,時間為45 min。色譜條件:C18反相色譜柱為固定相,V(水)∶V(甲醇)∶V(3.86%乙痠鈉溶液)∶V(4%乙痠溶液)=742:240:15:3為流動相,流速為1.2 mL/min,紫外檢測波長為254 nm,在此條件下頭孢氨芐和甲氧芐啶兩組分能很好地分離。本法的線性範圍分彆是頭孢氨芐為:27.6~276 μg/mL,甲氧芐啶為:5.56~55.6 μg/mL,平均迴收率為頭孢氨芐:99.32%,RSD=0.78%;甲氧芐啶:100.1%, RSD=0.57%。

A reversed-phase HPLC (RP-HPLC) method for the determination of the dissolution of compound cephalexin capsule was developed. A basket stirring technique was applied, with 4% acetic acid solution as dissolvent, at speed of 100 r/min for 45 min . A C18 reversed-phase column was used as fixed phase and water-methanol-3.86% sodium acetate-40% acetic acid (742∶240∶15∶3) as mobile phase. The flow rate was 1.2 ml/min and UV detection was performed at 254 nm. Cephalexin and Trimethoprim (TMP) could be separated in this condition. The linear ranges were 27.6~276 μg/mL for Cephalexin and 5.56~55.6 μg/mL for TMP. The recovery and RSD were 99.32% and 0.78% for Cephalaxin and 100.1% and 0.57% for TMP respectively.
