| titleOfInvention | Method for extracting 17(21)-hopene-12beta-diol out of aschersonia |
| abstract | The invention discloses a method for extracting 17(21)-hopene-12beta-diol out of aschersonia. The method comprises the following steps of: extracting, separating and purifying metabolite, namely, extracting in a quenching mode, concentrating so as to obtain a crude extract, passing the crude extract through a silica gel column of 160-200 meshes, carrying out gradient elution by using n-hexane and ethyl acetate, further passing through a silica gel column of 200-300 meshes, carrying out gradient elution by using petroleum ether and ethyl acetate, and finally recrystallizing so as to obtain the 17(21)-hopene-12beta-diol in the aschersonia. The method is simple in process, easy to operate, low in cost and high in purity; and materials are conveniently obtained. |
