| titleOfInvention | Preparation method for extracting vanillin from gastrodia elata |
| abstract | the invention relates to the technical field of medicines, in particular to a preparation method of vanillin, which comprises the following processing steps: (1) pulverizing vanillin, and reflux-extracting with ethanol; (2) purifying by macroporous resin; (3) separating by a high-speed counter-current chromatograph; (4) concentrating and drying to obtain vanillin. The method adopts ethanol reflux extraction, macroporous resin purification and high-speed countercurrent chromatography separation to extract the vanillin, has simple process, short extraction time, high extraction rate and low production cost, and can be used for industrial production. |
