目的:建立同时测定小儿清咽颗粒中哈巴苷、哈巴俄苷、绿原酸、咖啡酸、连翘苷含量的方法。方法:采用高效液相色谱法。色谱柱为Zorbax SB-C18,流动相为乙腈-0.1%磷酸溶液(梯度洗脱),流速为1.0 mL/min,检测波长为210 nm(0~13 min,哈巴苷)、327 nm(13~25 min,绿原酸、咖啡酸)、277 nm(25~29 min,连翘苷)、210 nm(29~40 min,哈巴俄苷),柱温为30℃,进样量为10 μL。结果:哈巴苷、哈巴俄苷、绿原酸、咖啡酸、连翘苷检测进样量线性范围分别为8.400~168.0 ng(r=0.999 6)、11.30~226.0 ng(r=0.999 8)、128.8~257.6 ng(r=0.999 3)、8.110~162.2 ng(r=0.999 6)、29.69~593.8 ng(r=0.999 4);定量限分别为33.39、451.2、515.2、324.5、1 188 ng/mL,检测限分别为8.348、112.8、128.8、81.12、297.0 ng/mL;精密度、稳定性、重复性试验的RSD<2.0%;加样回收率分别为96.39%~98.64%(RSD=0.83%,n=6)、96.60%~98.89%(RSD=0.89%,n=6)、96.28%~99.22%(RSD=1.25%,n=6)、96.49%~99.54%(RSD=1.16%,n=6)、96.26%~99.70%(RSD=1.30%,n=6)。结论:该方法操作简单、结果准确,适用于小儿清咽颗粒中5种成分含量的同时测定。

ABSTRACTOBJECTIVE:To develop a method for simultaneous determination of harpagide,harpagoside,chlorogenic acid,caffeic acid and phillyrin in Xiaoer qingyan granules.METHODS:HPLC method was adopted.The determination was performed on Zorbax SB-C18column with mobile phase consisted of acetonitrile-0.1%phosphoric acid solution(gradient elution)at a flow rate of 1.0 mL/min.The detection wavelength was set at 210 nm(0-13 min,harpagide),327 nm(13-25 min,chlorogenic acid and caffeic acid),277 nm(25-29 min,phillyrin),210 nm(29-40 min,harpagosid);the column temperature was 30℃,and sample size was 10 μL.RESULTS:The linear ranges of harpagide,harpagosid,chlorogenic acid,caffeic acid and phillyrin were 8.400-168.0 ng(r=0.999 6),11.30-226.0 ng(r=0.999 8),128.8-257.6 ng(r=0.999 3),8.110-162.2 ng(r=0.999 6),29.69-593.8 ng(r=0.999 4),respectively.LOQs of the 5 components were 33.39,451.2,515.2,324.5,1 188 ng/mL;LODs were 8.348,112.8,128.8,81.12,297.0 ng/mL,respectively;RSDs of precision,stability and reproducibility tests were all lower than 2.0%. The recoveries were 96.39%-98.64%(RSD=0.83%,n=6),96.60%-98.89%(RSD=0.89%,n=6),96.28%-99.22%(RSD=1.25%,n=6),96.49%-99.54%(RSD=1.16%,n=6),96.26%-99.70%(RSD=1.30%,n=6),respectively.CONCLUSIONS:The method is simple,accurate and suitable for simultaneous determination of 5 components in Xiaoer qingyan granules
