Methods The EtOH extract of radixes of Daphne genkwa was initially separated with silica gel chromatography eluted by petrol/ acetone gradient. 方法芫花根醇提物以硅胶柱层析,石油醚/丙酮梯度洗脱。
Study on extract technology of total extractions and hydroxygenkwanin in the leaves of Daphne genkwa Chemical components of non-polar fractions from ethanol extract of radixes of Daphne genkwa and their inhibition to acute inflammation 芫花叶中总提物和羟基芫花素的提取工艺芫花根醇提物弱极性组分化学成分及抗炎活性研究
The Studies on Pharmacology of the Total Flavones and Chemical Constituents from Radixes of Daphne Genkwa 芫花根总黄酮的药理作用和芫花根的化学成分研究
Aim to elucidate the chemical components of non-polar fractions from EtOH extract of radixes of Daphne genkwa and their inhibition to acute inflammation. 目的阐明芫花根醇提物弱极性组分化学成分及其对急性炎症的抑制活性。
If the first row interval numbers take zero as a Lower bound, then the character equation has pairs of conjugated imaginary radixes, and the system is in critical stability. 如果第一列区间数以零为下界,则特征方程有成对虚根,系统临界稳定。
Moreover, it is not necessary to change the circuit structure in order to realize multi-valued flip-flops of different radixes. 而且无需改变电路结构就可实现不同基的多值触发器。
