| titleOfInvention | A kind of preparation method of waxgourd seed flavone extract |
| abstract | The invention discloses a kind of preparation methods of waxgourd seed flavone extract, and steps are as follows:With volume fraction it is that 85-95% alcohol refluxs extract 2-4 time, each 2-3h by Chinese Waxgourd Semen, merging extracting solution, extracting solution is concentrated under reduced pressure to give medicinal extract;By medicinal extract to use petroleum ether, ethyl acetate and water saturated extracting n-butyl alcohol after appropriate water dissolution successively, acetic acid ethyl ester extract is obtained after extract liquor reduced pressure;Acetic acid ethyl ester extract is detached through silica gel column chromatography, uses volume ratio 50 successively:1,25:1,14:1,5:1 chloroform-methanol elution, collects 14:1 elution fraction, concentrates to obtain the final product.This method can effectively extract flavones ingredient in waxgourd seed, have significant antibacterial, anti-oxidant, antitumor action, and preparation method is simple and easy to operate. |
