| 中文摘要 | it is difficult to simultaneously isolate and purify flavonoids and polyhydroxystilbenes due to their similar polarities. in this study, we isolated and purified these compounds 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 two-phase solvent system, desoxy-rhaponticin and rhapontigenin were purified, and orientin, vitexin, isovitexin, and rhaponticin were eluted together. in the second step, ethyl acetate:water (1:1, v/v) was used as the two-phase solvent system, and orientin, vitexin, rhaponticin, and isovitexin were isolated and purified. purities of the isolated compounds were determined using hplc, while uv spectra, h- 1 -nmr, and c- 13 -nmr aided in structure identification. |
