摘 要:目的:优选莲松异搏停片中延胡索、苦参的提取工艺.方法:以延胡索乙素、苦参碱和氧化苦参碱提取量为指标,通过正交试验和单因素试验考察乙醇体积分数、溶剂用量、提取次数和时间对醇提工艺的影响.采用HPLC测定指标成分含量,流动相乙腈(A)-磷酸二氢铵溶液(B)梯度洗脱(0~10 min,10%A;10~25 min,10%~37%A;25 ~ 45 min,37%A),检测波长220 nm.结果:最佳提取工艺为加6倍量70%乙醇提取3次,每次2h;延胡索乙素提取量332.04 mg,苦参碱和氧化苦参碱总量3 192.08 mg.结论:优选的提取工艺稳定可行,建立的色谱条件可较好地分离3个指标成分.Objective - Radix in Liansong Yiboting To optimize extraction technology of Corydalis Rhizoma and Sophorae Flaveseentis tablets. Method: With extracting amounts of matrine, oxymatrine and tetrahydropalmatine as indexes, orthogonal test and single factor test was adopted to optimize extraction process by taking ethanol concentration, solid-liquid ratio, extracting times and time as factor. HPLC was employed to determine contents of index components with mobile phase of acetonitrile (A) -ammonium dihydrogen phosphate solution (B) for gradient elution (0-10 min, 10% A; 10-25 min, 10%-37% A; 25-45 rain, 37% A) and detection wavelength at 220 nm. Result: Optimum extraction technology was as following: extracted 3 times with 6 times the amount of 70% ethanol for 2 h each time. Extracting amount of tetrahydropalmatine was 332.04 mg, total extracting amount of matrine and oxymatrine was 3 192.08 mg. Conclusion: This optimized extraction technology was stable and feasible, these established chromatographic conditions had a good separation for three components.
