| titleOfInvention | A kind of method extracting separation .beta.-bitter acid from Flos lupuli (Flos Humuli Lupuli) |
| abstract | The present invention relates to a kind of method extracted from Flos lupuli (Flos Humuli Lupuli) and separate .beta.-bitter acid, this detailed process is: loaded by Flos lupuli (Flos Humuli Lupuli) compressor in subcritical ultrasonic extractor, R134a mixed solvent is passed through in extractor, the effective ingredient being extracted in material is dissolved in the R134a mixed solvent of liquid or subcritical state, and filtrate pumps in separator；Regulation temperature and pressure makes R134a in R134a mixed solvent be converted into gaseous state by liquid, separates with extracting solution, and the concentrated vaporizer of extracting solution containing methanol is concentrated to give hop extract, enters crystallize workshop section；Take a certain amount of hop extract to be placed in reactor, add water, stirring, left at room temperature, sucking filtration, collect insoluble matter；Insoluble matter is added water, stirring, left at room temperature, sucking filtration；Stirring sucking filtration, collects insoluble matter, obtains .beta.-bitter acid crude product.The present invention utilizes subcritical ultrasound assisted extraction technique, uses R134a mixed solvent as Extraction solvent, and in production, solvent is not required to special handling and can recover high-purity state. |
