高效液相色谱法同时测定黄连解毒胶囊中5组分的含量

目的:建立以高效液相色谱法同时测定黄连解毒胶囊中盐酸小檗碱、盐酸巴马亭、盐酸药根碱、黄芩苷、栀子苷含量的方法。方法:采用3种紫外检测波长同时进行测定,色谱柱为DiamonsilC18,流动相为水-甲醇-0.05%磷酸(梯度洗脱),柱温为35℃,流速为1.0ml/min,检测波长为345、280、238nm,进样量为10μl。结果:盐酸小檗碱、盐酸巴马亭、盐酸药根碱、黄芩苷、栀子苷进样量分别在0.105μg～1.680μg(r=0.9999)、0.045μg～0.720μg(r=0.9998)、0.065μg～1.040μg(r=0.9997)、0.190μg～3.040μg(r=0.9999)、0.145μg～2.320μg(r=0.9999)范围内呈良好的线性关系;平均加样回收率分别为99.11%、98.19%、97.21%、98.52%、99.22%。结论:本方法快速、重现性好、灵敏度高,可为黄连解毒胶囊提供更合理、可靠的质量控制方法。

Simultaneous Determination of 5 Compositions in Coptis Chinensis Detoxication Capsule by HPLC

OBEJETIVE:To determinate simultaneously the contents of berberine hydrochloride,palmatine hydrochloride,jatrorrhizine hydrochloride,baicalin and jasminoidin in coptis chinensis detoxication capsule by HPLC.METHODS:3different UV wavelengths were adopted simultaneous in the determination in which Diamonsil C 18 was taken as the chromatographic column and water-methanol-0.05%H 3 PO 4 (gradient elution)was taken as mobile phase,the column temperature was set at35℃and the flow rate was1.0ml/min,the detection wavelength were345nm,280nm and238nm respectively and the sample size was10μl.RESULTS:They took good linear relationships when the respective sample size of berberine hydrochloride,pal-matine hydrochloride,jatrorrhizine hydrochloride,baicalin and jasminoidin were at0.105μg～1.680μg(r=0.9999),0.045μg～ 0.720μg(r=0.9998),0.065μg～1.040μg(r=0.9997),0.190μg～3.040μg(r=0.9999)and0.145μg～2.320μg(r=0.9999);Their respective average recovery rates were99.11%,98.19%,97.21%,98.52%and99.22%.CONCLUSION:This method is fast,reproducible,sensitive,and which can provide a more reasonable and reliable quality control for coptis chinensis detoxi-cation capsule.
