罗布麻叶黄酮类成分的UPLC-Q-TOF-MS分析
Zhong yao cai = Zhongyaocai = Journal of Chinese medicinal materials(2014)
Abstract
目的:建立超高效液相色谱-四极杆飞行时间质谱(UPLC-Q-TOF-MS)对罗布麻叶中黄酮类成分分析的方法.方法:采用Alltima C18色谱柱(250 mm×4.6 mm,5μm),以乙腈-1%醋酸为流动相,梯度洗脱,流速为0.8mL/min,检测波长为254 nm,柱温为30℃.在电喷雾负离子模式下监测采集数据.结果:初步鉴定出11个黄酮类化合物,并同时测定其中6个黄酮的含量.6个黄酮的浓度与峰面积的线性关系良好(r>0.9996),加样回收率为94.3% ~ 103.3%.结论:该方法准确可靠,重现性好,可作为罗布麻叶内在质量评价的依据.
