Separation of Flavonoids in Natural Products Using High-speed Countercurrent Chromatography: Separation of Flavonoids from Soybean, Ampelopsis Grossedentata and Salix Alba
Flavonoids possess several bioactivities such as anticancer, preventing angiocardiopathy and antibiosis. The present paper mainly aims to the preparative separation of the flavoniods in extract of soybean, leaves extract of Ampelopsis grossedentata and bark extract of Salix alba.
Four isoflavone components were purified from soybean extract by high-speed counter-current chromatography (HSCCC). Two types of multilayer coil separation columns were used: a small column made of standard 2.6-mm I.D. PT...
