切换波长HPLC同时测定左金丸乙醇提取物中7种生物碱的含量
摘要
目的:建立同时测定左金丸乙醇提取物中表小檗碱、盐酸药根碱、黄连碱、盐酸巴马汀、盐酸小檗碱、吴茱萸碱和吴茱萸次碱含量的液相色谱法。方法:采用Kromasil C18(4.6 mm×250 mm
Objective: To simultaneously determine epiberberine
jatrorrhizine
coptisine
palmatine
berberine
evodiamine and rutaecarpine in Zuojin pill ethanol extracts.Method: The chromatographic analysis was carried out on a Kromasil C18 column(4.6 mm×250 mm
5 μm).The mobile phase comprised acetonitrile(A) and water phase(B) [0.1% phosphoric acid and 0.05% triethylamine].Detection was performed at a wavelength of 265 nm(0-40 min) and 225 nm(40-55 min).Result: Epiberberine
jatrorrhizine
coptisine
palmatine
berberine
evodiamine and rutaecarpine had a good linearity in the range of 0.275 9-17.66
0.267 0-17.09
0.262 5-16.80
0.221 4-14.17
0.948 7-60.71
0.050 4-3.229 and 0.044 9-2.874 mg·L-1.The average recovery was 100.4% with RSD of 1.8%
99.8% with RSD of 1.2%
100.2% with RSD of 2.1%
100.0% with RSD of 2.1%
99.0% with RSD of 2.0%
98.9% with RSD of 2.0% and 97.4% with RSD of 2.2%.Conclusion: This is a simple
accurate method for determining the content of epiberberine
jatrorrhizine
coptisine
palmatine
berberine
evodiamine and rutaecarpine in Zuojin pill ethanol extracts.
