Embodiment 1

[0014] Embodiment 1: The method for extracting extract by alcohol from grape pomace is carried out according to the following steps: the grape pomace is packed in a reaction tank, and adding concentration is 90% or more than 90% or less than 90% to the grape skin The edible alcohol, the weight of alcohol is 3 times, 4 times or 5 times of the weight of grape skin; secondly, heat for alcohol extraction, and carry out thin film evaporation and concentration of the extract to recover alcohol, and obtain grape skin pomace extract, the grape skin pomace extract The paste density is 1.0 to 1.4.

Embodiment 2

[0015] Embodiment 2: The method for extracting extract by alcohol from grape pomace is carried out according to the following steps: the grape pomace is packed in the reaction tank, and adding concentration is 90% or more than 90% or less than 90% to the grape skin The edible alcohol, the weight of alcohol is 3 times, 4 times or 5 times of the weight of grape skin; secondly, heat for alcohol extraction, and carry out thin film evaporation and concentration of the extract to recover alcohol, and obtain grape skin pomace extract, the grape skin pomace extract The density of the paste is 1.0 to 1.4; before the alcohol extraction, it is best to naturally ferment the grape pomace at a temperature of 36 or 38 degrees Celsius for 24 hours or 36 hours or 48 hours, or more than 48 hours.

Abstract

The grape skin dregs are placed into reactor tank, and edible alcohol is added into grape skin, heated to make alcohol extraction, the obtained extract is undergone the processes of film evaporation and concentration to recover alcohol and obtain the grape skin dregs extract. Said invention grape liver-tonifying capsule contains (wt%) 8-56% of lactose, 2-14% of mannitol and the rest grape skin dregs extract. Said grape liver-tonifying capsule possesses auxiliary protection action against chemical hepatic injury.
