| titleOfInvention | A kind of method that separation from chrysanthemum indicum prepares flavones ingredient |
| abstract | The invention discloses a kind of method that separation from chrysanthemum indicum prepares flavones ingredient.Processing step is：(1) chrysanthemum indicum raw material is crushed, and adds 5 10 times to measure industrial alcohol solution ultrasonic extraction 23 times, and extract solution is concentrated to give medicinal extract；(2) medicinal extract is dissipated with moisture, and respectively with organic solvent-normal hexane, ethyl acetate, extracting n-butyl alcohol, concentration acetic acid ethyl acetate extract obtains crude extract；(3) flavones ingredient (acacetin/robinin in crude extract is isolated and purified with high-speed counter-current chromatograph again, apiolin, cyanidenon, linarin), its two-phase solvent system is n-hexane chloroform methanol water, upper phase is fixing phase, lower phase is mobile phase, and UV-detector on-line monitoring collects each stream part vacuum concentration, crystallization, dries and both obtained.The present invention is simple to operate, and pollution is few. |
