HPLC测定连翘酯苷-β-CD包合物中连翘酯苷的含量 建立连翘酯苷-β-CD包合物中连翘酯苷的含量测定方法.采用高效液相色谱法,Thermo C18(250×4.6mm)以乙腈-水-冰醋酸为流动相,其比例为13:87:0.2.检测波长为332nm,流速为1.5mL/min,柱温25℃.连翘酯苷浓度在5.7-19.0μg·mL-1与峰面积积分值呈良好的线性关...
Within this work, representatives of the plagiochin and riccardin types, both containing one biaryl unit and one biaryl ether moiety, have been investigated for their stereochemical stabilities and electronic circular dichroism (ECD) by means of HPLC-UV and HPLC-CD in combination with quantum-...
Since (S)-UA is less abundant in nature than (R)-enantiomer, it is difficult to source, thus precluding a deeper investigation. Among the lichens producing UA, Cladonia foliacea is a valuable (S)-UA source. In the present work, we report on a rapid HPLC-UV/PAD-CD protocol suitable ...
HPLC法测定胆酸-HP—β—CD包合物中胆酸的含量
我们开发了一种基于CD9抗体固定化高效液相色谱-免疫亲和层析(CD9-HPLC-IAC)技术用于从微量血清中分离EV,从而进行下游蛋白质组分析。该方法可在30min内实现从40 μL的血清中分离出EV,EVs产量为8×109。
HPLC分析流程 一、梯度洗脱条件的设置 典型的梯度洗脱是用两种溶剂做流动相,弱溶剂 A 和强溶剂 B,在反相色谱分离中溶剂 A 大都是水,溶剂 B 是甲醇或者乙 jing 等强溶剂。所有的梯度洗脱中溶剂强度不断增加,即 B 的浓度不断增加。例如, 流动相中溶剂 B 的...
