Technique for preparing liverwort extract and application of it in preparing medicine for treating liver cancer and hepatitis B

The invention discloses two liverwort extracts: liverwort total flavonoids extract and liverwort terpene extract; the invention proves the liver cancer resistance and hepatitis B resistance effects of the two extract parts, and also discloses the application in preparations of the medicines used for treating hepatitis B and liver cancer. The extract method is shown as follows: liverwort raw material is pulverized and 10-20 folds dissolvent is added; the extraction is performed 2-3 times at 50-100 DEG C, 0.5-1.5 hours per time; the extract solution is filtered and concentrated to dry to obtain liverwort crude extract. The crude extract is extracted respectively by ligroin, acetidin and n-butanol. n -butanol extract is vacuum distilled, recovering solvent, condensed to dry; after dissolved by methanol, the crude extract passes through a chromatographic column (filled with silica gel or diatomite) which is firstly washed with chloroform and then with methanol, or passes through macroporous adsorptive resin column which is firstly washed with water, and then eluted with ethanol; methanol or ethanol is decompressed concentration at 40-50 DEG C; the concentrated solution is dried through vacuum drying, spray drying or freeze drying to get extract with total flavonoids content of 70-90%. Acetidin extract solution is decompressed and distilled, then the solvent is recovered and concentrated to dry; after being dissolved by methanol, the liquid passes through a silica gel chromatographic column which is eluted by dichloromethane; the dichloromethane eluent is decompressed and concentrated at 30-40 DEG C; the concentrated solution is dried through vacuum drying, spray drying or freeze drying to get extract with total terpenes content of 70-90%.
