| titleOfInvention | Method for preparing albiflorin and paeoniflorin |
| abstract | The present invention discloses a method for preparing high purity paeoniflorin and albiflorin simultaneously comprising: extraction of the raw material Paeonia Lactiflora by percolation or heating under reflux to obtain the Paeonia Lactiflora extract solution, then purification by macroporous absorption resin, alumina column and silica gel column in turn to obtain high purity paeoniflorin and albiflorin. The preparation method of the invention can provide high purity paeoniflorin and albiflorin with low price and energy-consumption by the identical procedure. The process is simple. The purification efficacy is high and the purification time is short. |
