| titleOfInvention | Method for preparing p-hydroxybenzaldehyde from brined radish |
| abstract | The invention discloses a method for preparing p-hydroxybenzaldehyde from a brined radish. The method comprises the following steps: step1, preparation of dried brined radish powder: slicing the brined radish, drying the sliced brined radish at 50 DEG C, pulverizing the sliced brined radish, sieving the obtained brined radish powder through a 20-mesh sieve to obtain the dried brined radish powder, putting the dried brined radish powder into a sealed bag, and storing the sealed bag in a dryer for later use; step2, preparation of crude brined radish extract; step 4, primary separation of the crude brined radish extract; step4, separation and purification of a component Y1; and step5, separation and purification of a component 1-2: dissolving the component 1-2 with methanol, performing separation through a reverse-phase silica gel column, eluting the obtained product with 50% of CH3OH, selecting a first flowing fraction, separating the first flowing fraction with positive-phase silica gel, eluting the first flowing fraction with petroleum ether, collecting 20th to 32nd flowing fractions, merging the flowing fractions; performing concentration, and drying solutions off to prepare p-hydroxybenzaldehyde. According to the invention, p-hydroxybenzaldehyde is separated from the brined radish for the first time, wherein p-hydroxybenzaldehyde is an effective antifungal component for the brined radish. The method is of great significance to secondary development of the brined radish. |
