OBJECTIVE
To develop a HPLC method to determine the content of jatrorrhizine, palmatine, berberine, and obacunone in Phellodendri Amurensis Cortex simultaneously. MEHTOD: The separations were carried out at 25 degrees C on a Phenomenex Gemini C18 column (4.6 mm x 250 mm, 5 microm) eluted with acetonitril and water containing 0.1% phosphoric acid in gradient mode. The flow rate was 1.0 mL x min(-1), detection wavelengthes were 345 nm for jatrorrhizine , palmatine, berberine and 210 nm for obacunone.
RESULT
The average recoveries of jatrorrhizine, palmatine, berberine, and obacunone were 98.94%, 101.17%, 96.22% and 98.90%, respectively.
CONCLUSION
The method is simple, accurate and repeatable, and can be used in content determination of jatrorrhizine, palmatine, berberine, and obacunone in Phellodendri Amurensis Cortex.
目的
建立同时测定黄柏中盐酸小檗碱、巴马汀、盐酸巴马汀和奥巴库酮含量的高效液相色谱法。方法：在25℃下，采用菲罗门Gemini C18柱（4.6mm×250mm，5μm），以乙腈和含0.1%磷酸的水为流动相进行梯度洗脱。流速为1.0mL·min-1，盐酸小檗碱、巴马汀、盐酸巴马汀的检测波长为345nm，奥巴库酮的检测波长为210nm。结果：盐酸小檗碱、巴马汀、盐酸巴马汀和奥巴库酮的平均回收率分别为98.94%、101.17%、96.22%和98.90%。结论：该方法简便、准确、重复性好，可用于黄柏中盐酸小檗碱、巴马汀、盐酸巴马汀和奥巴库酮的含量测定。
