Isolation and Purification of Six Bioactive Compounds from the Seeds of Trigonella foenum-graecum L. using High-Speed Counter-Current Chromatography

WANG Honglun and his teams isolated and purified flavonoids and polyhydroxystilbenes from Trigonella foenum-graecum L. seed extracts using high-speed counter-current chromatography (HSCCC) in two steps with two different kinds of solvent systems.
  In the first step, n-hexane:ethyl acetate:methanol:water (1:5:1:5, v/v) was used as the twophase solvent system, desoxy-rhaponticin and rhapontige...
