目的：应用双波长比值光谱法对银黄口服液中绿原酸和黄芩苷含量测定进行研究。方法：依据绿原酸和黄芩苷的比值光谱特征，选择266和342nm作为测定波长。结果：绿原酸线性范围2～20μg/ml,回收率98.9,RSD为1.58%;黄芩苷线性范围2～16μg/ml,回收率100.4%,RSD为1.32%。结论：本法为一种灵敏、准确和简便的分析方法，可在其他中药制剂中推广应用。
目的：應用雙波長比值光譜法對銀黃口服液中綠原痠和黃芩苷含量測定進行研究。方法：依據綠原痠和黃芩苷的比值光譜特徵，選擇266和342nm作為測定波長。結果：綠原痠線性範圍2～20μg/ml,迴收率98.9,RSD為1.58%;黃芩苷線性範圍2～16μg/ml,迴收率100.4%,RSD為1.32%。結論：本法為一種靈敏、準確和簡便的分析方法，可在其他中藥製劑中推廣應用。
목적：응용쌍파장비치광보법대은황구복액중록원산화황금감함량측정진행연구。방법：의거록원산화황금감적비치광보특정，선택266화342nm작위측정파장。결과：록원산선성범위2～20μg/ml,회수솔98.9,RSD위1.58%;황금감선성범위2～16μg/ml,회수솔100.4%,RSD위1.32%。결론：본법위일충령민、준학화간편적분석방법，가재기타중약제제중추엄응용。
OBJECTIVE：To determine of chlorogenic acid and baicalin in Yinhuang oral solution by dual-wavelength ration spectrometry.METHODS:With the feature of ratio spectrometry for chlorogenic acid and baicalin,266 and 342nm were chosen as their determination wavelengthes.RESULTS:Linear range of chlorogenic acid and baicalin were 2～20μg/ml and 2～10μg/ml respectively.The recovery of chlorogenic acid and baicalin rate were 98.9%(RSD=1.58%) and 100.4%(RSD=1.32%) respectively.CONCLUSION:As a precise,accute and sample method,it could be spread to the assay of other traditional Chinese medicine products.
