Yuanhu Zhitong prescription (YZP) is a famous traditional Chinese medicine formula, which is officially recorded in Chinese Pharmacopoeia for the treatment of stomach pain, hypochondriac pain, headache and dysmenorrhea caused by qi-stagnancy and blood stasis. It is the first report for the simultaneous determination of 12 active components in YZP.
A newly, simple, accurate and reliable method for the separation and determination of 12 active components (protopine, α-allocryptopine, coptisine, xanthotol, palmatine, dehydrocorydaline, glaucine, tetrahydropalmatine, tetrahydroberberine, imperatorin, corydaline, isoimperatorin) in YZP was developed and validated using HPLC-PAD.
The analytes were performed on a Phenomenex Luna-C18 (2) column (250×4.6 mm, 5.0 μm) with a gradient elution program using a mixture of acetonitrile and 0.1% phosphoric acid water solution (adjusted with triethylamine to pH 5.6) as mobile phase. Analytes were performed at 30°C with a flow rate of 1.0 mL/min.
The validated method was applied to analyze four major dosage forms of YZP coming from different manufacturers with good linearity (r(2), 0.99810.9999), precision (RSD, 0.242.89%), repeatability (RSD, 0.153.34%), stability (RSD, 0.143.35%), recovery (91.13~110.81%) of the 12 components.
The proposed method enables the separation and determination of 12 active components in a single run for the quality control of YZP.
元胡止痛方是著名的中药方剂,已正式载入《中国药典》,用于治疗气滞血瘀所致的胃痛、胁痛、头痛及痛经。这是首次同时测定元胡止痛方中12种活性成分的报道。
建立一种新的、简便、准确、可靠的方法,采用高效液相色谱-二极管阵列检测法(HPLC-PAD)分离并测定元胡止痛方中12种活性成分(原阿片碱、α-别隐品碱、黄连碱、黄藤素、巴马汀、去氢紫堇碱、青藤碱、延胡索乙素、四氢小檗碱、欧前胡素、紫堇碱、异欧前胡素),并进行方法学验证。
采用Phenomenex Luna-C18(2)色谱柱(250×4.6 mm,5.0μm),以乙腈和0.1%磷酸水溶液(用三乙胺调至pH 5.6)的混合溶液为流动相,采用梯度洗脱程序。柱温30℃,流速1.0 mL/min。
该验证方法用于分析不同厂家生产的元胡止痛方的4种主要剂型,12种成分线性关系良好(r²,0.9981~0.9999),精密度(RSD,0.24~2.89%)、重复性(RSD,0.15~3.34%)、稳定性(RSD,0.14~3.35%)、回收率(%,91.13~110.81%)均良好。
所建立的方法可一次进样分离并测定元胡止痛方中的12种活性成分,用于该制剂的质量控制。
