| titleOfInvention | A method of extraction prepares Balaenoptera borealis Lesson element from dioecious balanophora herb |
| abstract | Extraction prepares Balaenoptera borealis Lesson element from dioecious balanophora herb method that the invention discloses a kind of, this method extracts dioecious balanophora herb with methanol eddy, ethyl acetate extracts after extracting solution concentration, after acetic acid ethyl ester extract concentration and recovery, medicinal extract methanol dissolves petroleum ether extraction, takes methanol layer parlkaline alumina column to slough phenolic constituent, then through silica gel column chromatography, chloroform methanol affords Balaenoptera borealis Lesson element A, Balaenoptera borealis Lesson element B, and methanol water crystallization obtains high-purity monomer compound；The method of the present invention removes a large amount of impurity using solvent extraction, improve object content in loading sample, to save column chromatographic stuffing dosage and eluting solvent in subsequent column chromatography procedure, being not required to repeatedly column chromatography reduced column in the process to the dead adsorbance of object, time and solvent have been saved to greatest extent, has greatly improved preparation efficiency, have been reduced costs, and extraction time is short, recovery rate is high, realizes a large amount of, quick, inexpensive, efficient preparation. |
