Abstract

The invention discloses a standard apple extract as well as preparation and an analysis method of the standard apple extract. The preparation method comprises the following steps: removing kernels of Fuji apples, crushing into pieces, weighing for two parts accurately with 10Kg each part, soaking for one day respectively by absolute ethyl alcohol and water, filtering a filtrate and extracting residues twice, mixing the extract solutions twice, and carrying out vacuum concentration to be an extract. The standard apple extract can be used for preparing nutritional functional health products which have a weight losing effect, and have the functions of tonifying spleen, benefiting lung, improving the immunity and the like.

Description

technical field [0001] The present invention relates to chemically active components extracted from apples and its preparation and analysis methods, in particular to a standardized apple extract and its preparation and analysis methods. Functional health products such as lungs and immunity. Background technique [0002] Apple, a deciduous tree, the leaves are oval and serrated, and the flowers are white with a blush. The fruit is round and sweet or slightly sour. It is a common fruit, rich in nutrients, and has the functions of dietotherapy and auxiliary treatment. It is one of the four major fruits in the world. Apples are usually red, but also yellow and green, and are the fruit of a plant.
