一测多评法比较不同黄连炮制品中4种生物碱的含量
摘要
目的:比较黄连及其不同炮制品中表小檗碱、黄连碱、巴马汀、小檗碱的含量。方法:应用一测多评法同时测定黄连不同炮制品中4种生物碱的含量。Agilent TC-C18色谱柱(2)(4.6 mm×250 mm
berberine and palmatine in different processed of Coptis chinensis.Method:Quantitative analysis multi-components by single marker was used to determine the the contents of four alkaloids in different processed C.chinensis.Chromatographic conditions were:Agilent TC-C18 column(2)(4.6 mm×250 mm
5 μm)
mobile phase of acetonitrile-0.05 mol · L-1 potassium dihydrogen phosphate(50 ∶ 50
plus 0.4 g sodium dodecyl sulfate per 100 mL
phosphate-regulating pH 4.0)
detection wavelength 345 nm
column temperature 25 ℃
flow rate 1 mL · min-1
number of theoretical plates calculated to berberine hydrochloride should be greater than 2 000.Result:The contents of epiberberine
coptisine
berberine and palmatine in different processed of C.chinensis had different degrees of reduction.Conclusion:Established determination method in this test was rapid and economical
it could be used as quality testing method for different processed of C.chinensis.
