摘要:
目的:建立测定红车轴草中大豆苷元、染料木素、芒柄花素和鹰嘴豆芽素A含量的高效液相色谱方法.方法:Kro-masil C18色谱柱(250 mm×4.6 mm,5μm),流动相:乙腈-0.1%H3PO4(40:60),流速:1.0 mL·min-1,检测波长:254nm,柱温:25℃.结果:大豆苷元、染料木素、芒柄花素和鹰嘴豆芽素A的线性范围分别为0.0662～0.6620 μg,0.0978～0.9780μg,0.0866～0.8660μg和0.0992～0.9920μg.该方法回收率大豆苷元为98.9%(RSD=0.46%),染料木素为98.8%(RSD=1.21%),芒柄花素为98.8%(RSD=0.71%),鹰嘴豆芽素A为97.5%(RSD=1.33%).结论:该法简便、快速、准确.
