“…Because of little report on chromones, in the early method development stage, we investigated different extraction ways according to the studies of the other TCM [19][20][21], such as liquid-liquid extrac- tion (LLE), protein precipitation (PPT), aqueous bath extraction. Aether, ethyl acetate, ethyl acetate-isopropanol (95:5, v/v), and n-hexane-dichloromethane-isopropanol (5:4:1, v/v/v) was also tested as the extraction solvent.…”

“…Разделение в градиентном режиме осуществлялось на колонке Polaris C18-A 100 × 2,0 мм, Методика основана на одиночной жидко-жидкостной экстракции вещества, с использованием вещества хамазулен (99%, АО «МНПХ «Фитохимия») в качестве внешнего аналитического стандарта. При разработке методики использовали рекомендации, изложенные в [7]. Разделение было достигнуто на обращенно-фазовой колонке типа C 18 (неподвижная фаза) с использованием смеси ацетонитрил/водный раствор фосфорной кислоты (4:6) в качестве подвижной фазы.…”
