| titleOfInvention | The preparation method of phenols component in a kind of red winter Balaenoptera borealis Lesson |
| abstract | The invention discloses a kind of preparation methods of phenols component in red winter Balaenoptera borealis Lesson, and steps are as follows：Red winter Balaenoptera borealis Lesson herb is crushed, is placed in conical flask, adds petroleum ether, oscillation shakes up, closed and repeatedly shake, 25-35 DEG C of placement 8-10d, filtering volatilize petroleum ether, and addition volume fraction is 85-95% ethyl alcohol, heating and refluxing extraction 2-3h, filtering, filtrate, extracting solution are concentrated under reduced pressure to give medicinal extract；Medicinal extract is separated through silica gel column chromatography, successively uses volume ratio 50:1,30:1,25:1,14:1,5:1 chloroform-methanol elution, collects 14:1 elution fraction, is concentrated to obtain the final product.The preparation method can be effectively obtained phenols component in red winter Balaenoptera borealis Lesson, have anti-asthma, antineoplastic action, furthermore preparation method simple possible, easy to operate, can be mass-produced. |
