| titleOfInvention | The preparation method of flavones ingredient in a kind of turnip |
| abstract | The invention discloses a kind of preparation methods of flavones ingredient in turnip, and steps are as follows：Turnip root volume fraction 70-80% ethyl alcohol cold soaking is extracted 2-4 times, each 3-5d, combined extract, extracting solution is concentrated under reduced pressure to give medicinal extract；Gained medicinal extract is diluted with water, petroleum ether, ethyl acetate and water saturated extracting n-butyl alcohol are successively used, is concentrated under reduced pressure, obtains acetic acid ethyl ester extract；By acetic acid ethyl ester extract large pore resin absorption column chromatographic isolation, 8-10 column volume first is rinsed with 10% ethyl alcohol and removes big polar component, then with 11-13 column volume of 75% ethanol elution, collects 75% eluent, then separate through silica gel column chromatography, successively uses volume ratio 45:1,25:1,12:1,5:1 chloroform-methanol elution, collects 12:1 elution fraction, is concentrated to obtain the final product.Preparation method is simple for this, and flavone extract has significant anti-oxidant, anticancer activity in obtained turnip. |
