目的:建立测定小儿清肺止咳片中栀子苷含量的方法。方法采用反相高效液相色谱法,Diamonsil-C18柱,乙腈-水(12∶88)为流动相,流速为1.0mL? min -1,检测波长为240nm,柱温为30℃。结果栀子苷浓度在5.0~50.0μg? mL -1间具有良好的线性关系(r=0.9998),栀子苷平均回收率为100.4%,方法精密度(RSD)为0.44%(n=6)。结论该法可用于小儿清肺止咳片中栀子苷的含量测定。
目的:建立測定小兒清肺止咳片中梔子苷含量的方法。方法採用反相高效液相色譜法,Diamonsil-C18柱,乙腈-水(12∶88)為流動相,流速為1.0mL? min -1,檢測波長為240nm,柱溫為30℃。結果梔子苷濃度在5.0~50.0μg? mL -1間具有良好的線性關繫(r=0.9998),梔子苷平均迴收率為100.4%,方法精密度(RSD)為0.44%(n=6)。結論該法可用于小兒清肺止咳片中梔子苷的含量測定。
