Phenylethanoid glycoside extract froml., preparation method thereof and use as anti-liver injury medicament

Abstract

Provided are a phenylethanoid glycoside extract from the plantL., a preparation method thereof, and its use as an anti-liver injury medicament. The preparation method of the phenylethanoid glycoside extract comprises following steps: pulverizing dried whole plantL. and passing through 20-30 mesh sieve to obtainL. powder, adding 50%-95% ethanol solution whose mass is 8-20 times of the powder, soaking and extracting under reflux, filtering and collecting extract of the powder, and extracting a filter residue under reflux with 50%-95% ethanol solution whose mass is 8-10 times of the filter residue and collecting extract of the filter residue, combining, concentrating and subjecting to macroporous resin column chromatography, eluting successively by 10%, 30% and 50% ethanol solutions for four column volumes, respectively, collecting fraction eluted by the 50% ethanol solution and drying to obtain the phenylethanoid glycoside extract.
